Kaise KBLI121000 is a rechargeable lithium iron phosphate (LiFePO4) battery with a nominal voltage of 12.8 V, a capacity of 100 Ah and a nominal energy rating of 1280 Wh.
It uses 3.2 V, 100 Ah prismatic LiFePO4 cells and incorporates a Battery Management System (BMS) to monitor and protect the battery against abnormal charging and discharging conditions.
LiFePO4 technology offers a low self-discharge rate, has no memory effect and requires little routine maintenance. For this model, Kaise specifies a cycle life of more than 2,000 cycles at 80 % depth of discharge (DoD), under the manufacturer's stated conditions.
The recommended charging voltage is 14.6 V, with a recommended charging current of 20 A and a maximum charging current of 100 A.
For discharge, the battery supports 50 A continuously and up to 100 A as the maximum continuous discharge current. The BMS incorporates protection against overvoltage, undervoltage, overcurrent, short-circuit and temperature conditions.
A charger suitable for LiFePO4 batteries must be used and the specified electrical and temperature limits must be observed.
Up to four batteries can be connected in series. The Kaise LiFePO4 range also supports parallel connections to increase capacity, subject to the manufacturer's installation requirements.
Typical applications include solar and wind energy systems, backup power, small UPS systems, motorhomes, marine applications, electric wheelchairs and scooters, electric bicycles and other installations compatible with LiFePO4 batteries.
The battery has an ABS enclosure with an IP65 protection rating and M8 threaded terminals. The specified terminal tightening torque is 9 to 11 N·m.
Do not short-circuit, crush, dismantle, heat, incinerate or immerse the battery. For long-term storage, Kaise specifies approximately 50 % state of charge, a clean, cool, dry and ventilated location, and recharging every three months.
