LiWATT 12.8V-100Ah
Feature of LiFePO4 Battery
- Longer Cycle Life: Offers up to 10 times longer cycle life and 5 times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership
- Lighter Weight: The weight is approximately 40% to 50% less than that of a lead acid battery. When compared to lead acid batteries, it can conserve space.
- Higher Power: Delivers twice power of lead acid battery,even high discharge rate,while maintain high energy capacity
- Superior Safety: The chemistry of lithium iron phosphate avoids the possibility of explosion or combustion caused by heavy impact, overcharging, or short circuit circumstances.
- Wider Temperature Range: -10℃~60℃
Functions of BMS
- Over charge detection function
- Over discharge detection function
- Over current detection function
- Temperature protection function
- Short circuit detection function
- Balance function
