Smart and Safe
Our latest generation LiFeMnPO4 chemistry is much safer and more reliable than both the traditional lead acid batteries and the standard Li-ion cells. NO dangerous fumes or possibility of lithium fire, just pure reliable and safe power. Each cell is monitored with a sense board that individually balances the cell and reports voltage and cell temperature to our proprietary battery management system (BMS).
The BMS monitors the battery and automatically disconnects the battery in the event of under-voltage or high temperature. A built in, replaceable fuse protects against short circuits.
Light and Tough
Spirit Modular Batteries are 67% lighter than same capacity lead acid batteries. They require no ventilation and can operate in a wide range of temperatures, from -4°F to 150°F (-20°C to 65°C) while discharging, and 32°F to 150°F (0°C to 65°C) while charging. With rapid charging, the batteries can be recharged in as little as an hour and run for days.
Spirit Modular Batteries provide near constant voltage as they are discharged. There is no power fade or light dimming until the battery is almost discharged. The cells are guaranteed for over 2,000 cycles at 80% depth of discharge (DoD) and are completely maintenance free for the duration of their lifetime. 2,000 cycles means you can discharge the battery to 20% and then charge it again to 100% every day for 5 years and still expect amazing performance!
Easy to Install & Customize
Spirit Modular Batteries are specifically designed for custom applications where flexibility is required, but can also be used as drop in replacements for lead acid batteries. They can be installed in series to accommodate 12V, 24V, 36V, or 48V systems, and they can be installed in parallel for arbitrary system capacity sizes.
