Three compact batteries can provide substantial storage, but their combined capacity doesn’t tell us how well they’ll suit a specific system. In this HumsiENK 3-pack review, we’ll assess the 300Ah, 12.8V configuration, key protection features, installation considerations, and trade-offs. We’ll also examine charging and cold-weather limits, because those details can determine whether this setup fits your power needs.
Key Takeaways
- Three batteries provide 300Ah at 12.8V, totaling 3,840Wh of rated energy.
- Each 100Ah battery weighs 19.73 pounds and measures 8.4 × 6.6 × 10.2 inches.
- The 100A BMS protects against common electrical and temperature faults but limits continuous output.
- Up to four batteries can be configured for systems reaching 48V or 20kWh; verify charger compatibility.
- The batteries are rated for 5,000 cycles and carry a five-year warranty, but cold-weather cutoff may require extra protection.
Three-Battery 100Ah Set
HumsiENK’s three-battery set provides 300Ah of capacity at 12.8V, or 3,840Wh total. Each 100Ah battery stores 1,280Wh, weighs 19.73 pounds, and measures 8.4 × 6.6 × 10.2 inches. Together, the units weigh 59.2 pounds, which helps us assess handling and available space before installation.
You can connect up to four batteries in series, parallel, or a combined configuration, supporting systems up to 48V and 20kWh. These installation options let’s match voltage and capacity to the application. Supported charging strategies include solar, generator, and grid power; the manufacturer states a full charge takes about two hours.
Detailed features
Beyond capacity and charging, each battery includes a 100A BMS that protects against overcharge, over-discharge, overcurrent, short circuits, and high or low temperatures. This Battery management system disconnects discharge current above 300 ± 50A and shuts down below −4°F (−20°C). Temperature protection operates within the stated −4°F to 158°F range.
The impact-resistant case carries an IP67 waterproof rating, while A+ grade cells have undergone 999 laboratory tests, according to HumsiENK. The batteries support series or parallel connections, up to four units in either configuration, and can combine for systems reaching 48V and 20kWh. Each weighs 19.73 pounds and measures 8.4 × 6.6 × 10.2 inches.
Pros and Cons
We’ll weigh the three-pack’s 5,000-cycle rating, 100A BMS protections, and flexible system configurations against its charging, temperature, and installation limits.
We’ll distinguish manufacturer-stated specifications from practical considerations. This comparison will help you assess whether the batteries suit your application.
Pros
The three-pack’s main advantage is its combination of usable capacity and flexible installation: each 12.8V, 100Ah battery stores 1,280Wh, weighs 19.73 pounds, and fits a Group 24 footprint. We can connect units in series or parallel to build systems up to 48V and 20kWh, supporting RV, marine, solar, and backup applications.
Cycle longevity is strong, with up to 5,000 cycles at 100% depth of discharge and a stated lifespan of 10 years. The 100A BMS adds temperature protection, plus safeguards against overcharge, over-discharge, overcurrent, and short circuits. IP67 construction and a five-year warranty further support versatile installation and long-term use.
Cons
Despite its broad compatibility, this three-pack has practical limits: each battery’s 100A BMS restricts continuous output, and the low-temperature cutoff below −4°F prevents charging or discharging in colder conditions. These cold weather limits may require insulated installation or a separate heating solution for winter use.
We should also verify charging compatibility with our solar controller, generator, or grid charger; support for these sources doesn’t guarantee every charger’s voltage profile will suit LiFePO4 chemistry. The set weighs 59.2 pounds, so handling all three batteries takes effort. Finally, the manufacturer’s two-hour full-charge estimate depends on adequate charger output and isn’t assured in every setup.
Concluding thoughts
For RV, marine, and off-grid systems, the HumsiENK three-pack offers 3,840Wh of rated capacity, built-in 100A BMS protection, and flexible series or parallel configurations.
Its compact Group 24 format, IP67-rated construction, and protections against temperature extremes support varied installations, while the five-year warranty adds a defined coverage period.
We’d consider the set for ideal users who need modular 12V storage and may expand toward 48V or 20kWh. The stated 5,000-cycle lifespan could improve long term value versus lead-acid, though actual service life depends on operating conditions.
Before buying, we’d verify charging compatibility, load requirements, and cold-weather performance for your specific system.
Frequently Asked Questions
What Accessories Are Included With the Humsienk Three-Pack?
You’ll receive six insulating caps and mounting hardware: six M8 screws measuring 14 mm and six measuring 16 mm. Included cables aren’t listed in the package contents, so we can’t confirm any are supplied.
Which Certifications Does This Battery Carry?
We can’t call its certification list endless: the battery carries SDS, UN38.3, FCC, CE, and RoHS certifications. We don’t see UL certification listed, so don’t assume it has UL approval or CE compliance beyond its stated certification.
What Is the Manufacturer’s Warranty Period?
We get a five-year manufacturer’s warranty. For Warranty Coverage, check your purchase documentation for applicable terms; for the Claim Process, contact HumsiENK with proof of purchase and product details, since specific procedures aren’t provided here.
Can These Batteries Be Charged Using Solar Panels?
Yes, we can charge these batteries using solar panels. Solar Charging supports the manufacturer’s stated two-hour full-charge estimate. For Panel Compatibility, we should match the panels and charge controller to the batteries’ 12.8V requirements.
What Battery Group Size Is This Model Compatible With?
This model uses Group 24 sizing and supports BCI Group 24–31 standards. For Battery Fitment, we recommend checking your compartment dimensions and terminal clearance; the battery measures 8.4 × 6.6 × 10.2 inches.
Conclusion
We see the HumsiENK three-pack as a practical way to build 300Ah of 12.8V LiFePO4 storage, or 3,840Wh, for RV, marine, solar, and backup systems. Its IP67 cases, 100A BMS, and five-year warranty add useful protection, but we’d still verify continuous-output needs, charger compatibility, and cold-weather cutoff before buying. At 19.73 pounds per battery, installation also takes planning. Like a well-sized reservoir, this set can support dependable power when its limits match our system’s demands.
