【Premium LiFePO4 Cell & UL Safety】Built with premium Grade A LiFePO4 cells, this 12V 100Ah battery delivers high energy density, stable output, and strong power performance. UL tested and listed, it meets the highest safety standards required for US markets. It is ideal for solar homes, RVs, campers, trolling motors, and off-grid power systems 【Intelligent BMS & Auto-Recovery】Equipped with an advanced built-in BMS, the battery provides automatic overload recognition, over-discharge protection, and quick recovery. When an overload occurs, the battery shuts down safely and automatically resumes once the issue is resolved. It supports 4S4P expansion for higher power needs, perfect for RVs, solar setups, home energy storage, and 30–70 lbs trolling motors 【Superior Voltage Stability for Marine Use】Designed for long-lasting power on the water, this LiFePO4 battery features built-in TVS protection technology. It effectively guards against voltage spikes and surges, ensuring stable performance even in rough water conditions. This protects both the battery and your motor from damage, giving you confident and reliable power on every trip 【10x Longer Life Than Lead-Acid】Grade A LiFePO4 cells support 4000+ cycles at 100% DOD, 6000 cycles at 80% DOD, and an impressive 15,000 cycles at 60% DOD. Compared to traditional lead-acid/SLA/AGM batteries (which only last 3 years / 200–500 cycles), this battery is a long-term, cost-saving upgrade for boats, RVs, solar systems, and daily off-grid use 【Correct Charging & Temperature Care】To ensure maximum performance and long life, please use a LiFePO4-specific charger to avoid charging failure caused by low voltage [automotive-grade lithium batteries] WOXABHSL 12V100Ah LiFePO4 batteries have excellent quality because they are made from automotive-grade LiFePO4 cells with higher energy density, more stable performance and higher power. The battery inside the battery has the highest safety level based on the UL test certificate. [Widely Uses]: Lithium-iron batteries are very suitable for solar households, RVs, campers, RVs, off-grid applications, wheelchairs, emergency lighting, ships, golf carts, towing motors, home energy storage, computer backup power, solar panels wind energy storage and more. [10-year service life] WOXABHSL LiFePO4 batteries can provide 4,000 million 15000 cycles (10 times longer), 4000 cycles at 100% DOD, 6000 cycles at 80% DOD, 15000 cycles at 60% DOD. [light weight-easy to move] the WOXABHSL LiFePO4 battery weighs only 22.05lb per module, which is only one pound of the weight of the lead-acid battery. Lithium iron phosphate batteries are 50% lighter than lead-acid batteries of the same capacity. [95% * efficiency] the flat discharge curve of WOXABHSL LiFePO4 batteries is maintained above 12.8V at a capacity utilization rate of up to 95% *, which is astronomically higher than that of lead-acid batteries with a running time of only 50%. This product is the best choice for outdoor camping power supply and indoor easy installation. No memory effect, no matter what state the battery is in, it can be used as soon as it is charged.
