It features an advanced built-in BMS with 20+ layers of protection, including low and high-temperature cut-offs. This protects your battery during charging and discharging, even in extreme conditions. Plus, all internal battery cells are UL tested and certified to ensure maximum safety and reliability. 【Upgrade to a More Powerful LiFePO4】HQST lithium batteries outperform traditional lead-acid batteries with a superior lifespan of up to 10 years, compared to just 1 to 3 years for most lead-acid options. Weighing only 22 lbs, this 12V LiFePO4 battery is lighter, more compact, and delivers more power than standard lead-acid batteries. Plus, it comes with an integrated BMS for enhanced safety—something SLA batteries simply don’t offer. 【Series & Parallel Connections for Expandable Power】The HQST 12V 100Ah lithium battery supports both series and parallel configurations. Easily build a 24V, 36V, or 48V battery bank with series wiring, or expand your capacity to 12V 200Ah, 300Ah, or 400Ah through parallel connections. For larger setups, you can link up to 16 batteries in series and parallel to create a powerful 20.48 kWh home backup system—ideal for power outages or hurricane season. 【Optimal Charging & Discharging Performance】The HQST 12V 100Ah LiFePO4 battery delivers full 100% usable capacity, unlike traditional SLA batteries that only offer about 50%. With a continuous discharge current of up to 100A, it’s powerful enough to run most household appliances. For best results, charge at 20A, with a maximum charging current of 50A. Recharge easily using a LiFePO4 charger, a solar panel system (must with a charge controller), or a DC-DC charger. 【Wide Range of Applications】The HQST lithium battery includes a built-in LED display that shows real-time power capacity, voltage, and charging/discharging current—taking the guesswork out of your setup. Perfect for RVs, trailers, trolling motors, boats, off-grid cabins, and home backup power during outages or hurricane season. Show more
