About this item

【10-Year Lifespan & Built-in BMS】 Our Dr.Prepare 100Ah LiFePO4 battery offers a 10-year product support and lifespan. The advanced built-in BMS system provides 20+ layers of protection — including low- and high-temperature cut-off — to protect the battery during charging and discharging, even under extreme conditions. Plus, all internal battery cells are UL-tested and certified to ensure maximum safety and reliability.
【Series & Parallel Connections for Powerful Backup Power】 Dr.Prepare 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.
【Upgrade to Dr.Prepare LiFePO4 Batteries】 Dr.Prepare lithium batteries outperform traditional lead-acid batteries with a longer lifespan of up to 10 years, compared to just 1–3 years for most SLA options. Weighing only 22 lbs, this 12V LiFePO4 battery is lighter and delivers more consistent power than standard SLA batteries. Plus, it features an integrated BMS for enhanced safety — a level of protection SLA batteries simply don’t offer.
【Trolling Motor, Solar RV, Home Backup】 When using the battery with a trolling motor, we highly recommend installing a 60A–100A circuit breaker between the battery and your device to prevent overdischarging. These LiFePO4 batteries are also perfect for RV solar setups, off-grid camping, and home backup power during outages or hurricane season.
【Charging & Discharging Tips】 The optimal charging current is 20A (max 50A). For safe and efficient charging, use a compatible AC-to-DC LiFePO4 battery charger or a solar panel system with a charge controller. The max continuous discharging current is 100A. After a full discharge at 100A, avoid immediate recharging at 50A, as it may trigger the high-temperature charging protection.
