12V 100AH Group 24 LiFePO4 Battery review

Looking for a compact, powerful, and weather-ready battery for our RV, camper, or off-grid system?

Product Overview

We tested the 12V 100AH Group 24 Self-Heating LiFePO4 Lithium Battery with Touchable Smart Display & APP Monitoring, Built-in 100A BMS,1280W Load Power, 5000+ Cycles, Perfect for RV/Camper, Solar, and Off-Grid to see how it performs in practical situations. We found that this battery aims to combine small size, low weight, modern monitoring, and temperature-smart behavior in a package intended as a direct upgrade over traditional 12V deep cycle options.

What this product promises

The manufacturer positions the battery as a Group 24-sized LiFePO4 pack that delivers 1280Wh of usable energy with a long cycle life and smart features. We appreciated that it targets users who want better energy density and longevity than lead acid while keeping installation and monitoring straightforward.

Key Specifications at a Glance

We summarized the core specs so we can see the fundamental numbers before getting into subjective impressions. The table below captures the headline figures we used during testing and comparison.

Design & Build Quality

We liked the compact Group 24 footprint because it makes retrofits into tight battery bays much easier than bulkier 12V LiFePO4 modules. The enclosure feels sturdy and the terminals and mounting points are sensibly placed for quick fastening in an RV, boat, or trailer.

Size and weight advantages

Being 25% smaller and roughly half the weight of equivalent lead acid units makes handling and installation far simpler for us. At 23.14 lbs, it’s much more manageable for a two-person install and reduces strain on mounting rails or trays.

Terminal layout and mechanical design

The terminal hardware is robust and well-located to avoid cable congestion, and the casing shows thoughtful ventilation and impact protection. We also appreciated the option to orient the battery in any position, which increases flexibility in constrained spaces.

Performance & Capacity

We put the battery through real-world discharge cycles to evaluate usable capacity, voltage stability under load, and efficiency when charging from a solar charge controller or AC charger. The 1280Wh rating aligns with a true 12.8V x 100Ah pack, and under normal loads we consistently saw usable energy near that figure.

Usable capacity in practice

At moderate discharge rates (C/10 to C/5), the battery delivered close to the full rated capacity and maintained voltage well into deeper discharges. For many RV setups where daily draw is steady but not extreme, we were able to rely on a large portion of the 100Ah without hitting steep voltage sag.

Load handling and current delivery

With a built-in 100A BMS, short-term currents up to the BMS limit are handled cleanly, and the battery maintained stable output when running accessories and an inverter simultaneously. We successfully supported inverters drawing substantial power up to near the 1280W continuous load power rating for reasonable periods.

Charging Behavior & Self-Heating Function

One standout feature is the automatic self-heating function that activates below 32°F when the battery is connected to a charger. We tested this in cooler conditions and found the process both safe and automatic, with the heating ceasing around 41°F and then enabling normal charging.

How the self-heating works for us

The self-heating is controlled by the onboard BMS: when the battery senses a charger and the internal temperature is below the activation threshold, it supplies internal heating to protect the cells during charging. In practice, this means we can leave the battery installed in colder climates without worrying that a charger will damage it by attempting to force charge at subzero temperatures.

Charging profiles and compatibility

The battery responds well to standard LiFePO4 charging profiles and is compatible with many modern DC-to-DC chargers, multi-stage AC chargers, and solar charge controllers configured for LiFePO4 chemistry. We recommend setting chargers to the appropriate float and bulk voltages for LiFePO4 and ensuring temperature compensation is disabled where the battery’s internal thermal system is managing low-temp charging.

BMS & Safety Features

We appreciate that the battery includes a built-in 100A BMS providing multiple layers of protection, including over-charge, over-discharge, over-current, overheating, and short-circuit protection. The presence of low-temperature cutoff also protects cells from damage during freezing conditions.

How protection behaved during testing

During simulated faults and heavy load events, the BMS acted promptly to cut output and safeguard the battery, and then restored normal operation once conditions returned to safe ranges. This kind of automatic intervention gives us confidence when the battery is used in mobile environments where loads can change quickly.

Thermal management and impact resistance

The LiFePO4 chemistry itself offers inherent thermal stability and safety, and the battery casing adds to that security with robust construction. While no battery is indestructible, our stress checks showed no thermal runaway tendencies or unexpected heating under rated conditions.

Touchable Smart Display & APP Monitoring

The included touchable smart display is a useful local interface that shows state of charge, voltage, current, temperature, and other key parameters. Paired with Bluetooth and a dedicated app, we can monitor the battery remotely and track its history and status from our phone.

Onboard display usability

The touch display is bright, responsive, and easy to read at a glance, which is great for quick checks when we’re onboard the RV or at the helm of a boat. The layout is intuitive and provides actionable information without having to power up additional equipment.

App experience and connectivity

The Bluetooth app adds convenience by letting us view detailed metrics, check alarm history, and make simple configuration choices from our phone. In our experience the connection was stable at typical distances and remained responsive while the battery was in use.

Expandability & System Integration

One of the benefits is the ability to expand capacity by connecting up to 10 batteries in parallel, or to build higher-voltage packs by series wiring up to 4 in series (Max 4P4S). This gives us flexibility to scale for larger systems without moving to entirely different modules.

Practical implications of expandability

For larger RVs, off-grid cabins, or solar installations, adding parallel modules allows stepwise capacity increases as budget or demand grows. Series connections enable higher-voltage systems (24V, 36V, 48V) for applications with higher DC bus needs, though we always emphasize matching BMS settings and installation best practices.

Installation tips for multi-battery setups

When we wired multiple units together, we followed manufacturer guidance on balancing, cabling, and common-mode grounding to prevent imbalances and to ensure consistent charging across the string. Using equal-length cables and secure bus bars helps maintain uniform performance.

Use Cases & Ideal Applications

We evaluated real-world uses such as RV house banks, campers, travel trailers, small marine installs, and solar off-grid systems to see where the battery shines. Its compact size, reduced weight, and smart features make it especially appealing in space-constrained installations and for users who want a low-maintenance alternative to lead acid.

RVs, campers, and travel trailers

For RVs and campers, the balance of capacity and size is ideal for small-to-medium systems where under-seat or under-bench mounting options are common. The lighter weight reduces overall vehicle mass and can improve fuel economy slightly, while the smart display and app make onboard monitoring easier.

Solar and off-grid use

In small off-grid solar installations, the battery pairs well with MPPT controllers and inverters for daily cycling; the long cycle life makes it a good investment for owners prioritizing longevity over low upfront cost. We found that for weekend cabins or tiny homes, this battery offers a great balance of price, performance, and durability.

Comparison with Lead Acid and Other LiFePO4 Options

We compared the TEMGO Group 24 LiFePO4 to typical flooded, AGM, and other LiFePO4 batteries to identify where it outperforms and where compromises exist. In short, it beats lead acid by a wide margin in weight, usable capacity, and cycle life, and it competes well against other LiFePO4 options thanks to its compact form factor and integrated features.

Why it outclasses lead acid

Compared to a same-capacity lead acid, our pack delivers roughly five times the cycle life and nearly half the weight while maintaining higher usable capacity without deep discharging concerns. For users who frequently cycle batteries or who want less maintenance, the LiFePO4 choice is compelling.

How it stacks up against larger LiFePO4 modules

Against larger or higher-capacity LiFePO4 modules, the main tradeoff is absolute energy per unit versus convenience of size and weight. The Group 24 format makes installation more flexible and attractive for retrofits, while larger modules might offer economies of scale for stationary installs where space and weight are less critical.

Real-World Testing and Experience

We ran a series of tests simulating daily RV usage, cold-weather charging, and load surges to evaluate reliability and behavior under stress. The battery consistently delivered expected capacity, handled loads cleanly, and the self-heating feature worked as advertised in sub-32°F conditions.

Typical day-to-day performance

During a typical day with fridge, lights, fans, and occasional microwave or inverter use, the battery provided stable voltage and predictable runtime estimates through the app. We could plan our energy usage more effectively with the accurate state-of-charge readouts, which reduced our need to conservatively ration power.

Cold-weather performance

In cold ambient conditions, we were impressed that the BMS initiated internal heating when a charger was present and that charging resumed properly once the battery warmed to its safe threshold. That removed a major logistical headache when keeping batteries in an unheated compartment during colder months.

Installation and Mounting

We found that mounting and wiring the battery was straightforward, especially because we could position it in any orientation and because it is physically smaller than many 12V deep-cycle batteries. Proper cable sizing and secure connections remain essential, as with any battery installation.

Mounting considerations

Because the battery can be installed in any orientation, we had flexibility in where to place it, which is especially helpful in cramped battery wells. We still recommend bolting it down securely and ensuring good ventilation around the battery to keep ambient temperatures within recommended ranges.

Wiring and fusing

We used appropriately sized cables and recommended inline fuses or breakers sized to the BMS rating to prevent damage from short circuits and to meet safety codes. When paralleling units, we kept cable lengths equal and used common busbars to maintain balanced distribution.

Maintenance and Care

One of the biggest advantages for us was the minimal maintenance requirement compared to lead acid batteries. No watering, no acid-sulfur smell, and no equalization charging simplify ownership considerably.

Routine checks we recommend

We advise periodic visual inspections of terminals and housing, ensuring connections remain tight and corrosion-free, and occasional app checks to monitor cell temperatures and state-of-charge trends. Keeping firmware (if applicable) and charger settings compatible with LiFePO4 chemistry is also prudent.

Long-term storage tips

For long-term storage, maintaining a partial state-of-charge (around 40–60%) and avoiding prolonged exposure to extreme temperatures will help maximize life. The battery’s internal management helps protect cells, but good storage practices extend the service life further.

Longevity and Warranty

The manufacturer states a five-year service life and 5000+ cycles, which aligns with LiFePO4 expectations when cells are treated properly. Based on our usage patterns and test cycles, we expect the battery to retain a significant portion of its capacity over many years.

Expected life in real conditions

For typical RV or off-grid applications with daily shallow-to-moderate cycling, we expect the battery to maintain usable capacity for multiple years with minimal degradation. The high cycle life is one of the main reasons we see this as a better long-term investment than lead acid alternatives.

Support and service

The company offers friendly 24/7 customer support and stands behind their product with a clear service-life commitment. When we communicated with support during setup questions, responses were helpful and timely.
