3 Module 15.36kwh 48V Lifepo4 Lithium Iron Phosphate Ground Type ESS Stackable Battery Pack
ESS Lithium Battery Matters needing attation
1. Use environment of lithium battery: charging temperature is 0°C-45C;
2. The original charger must be used;
3. Do not put the battery in a high temperature environment, and do not heat it, close to the fire or expose
it to the sun.
4. Do not connect the positive and negative terminals of the battery in the opposite direction. Do notdestroy, disassemble or short circuit the battery;
ESS Lithium Battery Features
1. 3+ Cycles a day
With a large cycle life and high C-rate capacity our batteries can be discharged 3 or more times per day, allowing you to take full advantage of peak pricing.
2. 100% Depth of Discharge
By using a Lithium Titanate chemistry, Wise Energy Battery takes full advantage of the entire battery capacity.
3. Extreme Safety
Our Lithium Titanate battery chemistry is the safest in the market. It’s non-explosive and withstand high temperature up to 240℃ without thermal runaway.
