Product description

Product details

Grade A

Home Energy Storage Deep Cycle Efficiency: Round-trip charge efficiency of 93 percent or higher minimises energy loss in daily solar charge-discharge cycles, reducing total household electricity cost compared to AGM or GEL lead-acid home storage alternatives. Flat discharge curve maintains stable inverter input voltage from 100 percent down to 20 percent state of charge, preventing low-voltage inverter shutdowns during overnight loads.

8000 Cycle Long-Life Residential Storage: Over 8000 rated charge-discharge cycles at 80 percent depth of discharge gives this battery the longest service life in the LiFePO4 range, making it the most cost-effective choice per cycle for homeowners planning a 15 to 20-year solar storage installation horizon.

Power Wall Scale 12V Storage Bank: Multiple units in parallel build 600Ah, 900Ah or larger 12V storage banks delivering power-wall scale energy reserves for whole-house backup, time-of-use tariff arbitrage and extended off-grid autonomy without high-voltage battery system complexity.

Certified Home Storage Supply: CE marked, RoHS compliant, IEC62619 stationary storage certified. OEM residential energy storage brand programs from 100 units.

Frequently asked questions

Our 12V 200Ah packs use Grade-A 3.2V 300Ah prismatic LiFePO4 cells in 4S configuration from certified partner factories. All incoming batches are screened before assembly for open-circuit voltage consistency (±5mV), 1kHz AC internal resistance (≤0.25mΩ per

Lead-acid chargers use a 13.8V float voltage and bulk/absorption/float profile incompatible with LiFePO4 chemistry. This battery requires a dedicated LiFePO4 charger with 14.6V CV charge cut off and 12V discharge cut off. Incorrect chargers will result in incomplete charging, shortened cycle life and repeated BMS protection triggers. Compatible charger recommendations and supply are available on request, please consult before first charge.

Charging below 0°C is unsafe for LFP chemistry, sub zero temperatures cause lithium plating and permanent cumulative capacity loss. The built in 4S BMS includes low temperature charge protection that blocks charging under 0°C. For cold climate installations (RV, off-grid, marine), we recommend a self heating solution or temperature controlled storage and charging. Discharge capacity at -20°C is 15 to 20% lower than the 25°C rating, which is normal for LFP batteries.

OEM customization (private label, custom logo, packaging artwork) and standard spec changes (terminal layout, cable length, enclosure color) both carry a 100-unit MOQ. Lead time is 15 to 25 business days after artwork/spec approval and deposit receipt. We also support ODM projects (modified BMS parameters, custom voltages, IP-rated enclosures). Share your technical requirements for a feasibility assessment.
