Kaise KBLI12400 is a rechargeable lithium iron phosphate (LiFePO4) battery with a nominal voltage of 12.8 V, a capacity of 42 Ah and a nominal energy rating of 537.6 Wh.
It uses LiFePO4 cells and incorporates a Battery Management System (BMS) to monitor and protect the battery against abnormal operating conditions. This technology offers a low self-discharge rate, has no memory effect and requires no routine maintenance.
The battery provides more than 2,000 cycles at 80 % depth of discharge (DoD) under the conditions stated by the manufacturer.
The recommended charging voltage is 14.6 V, with a recommended charging current of 8.4 A and a maximum charging current of 21 A. For discharge, it supports 21 A continuously and up to 42 A as the maximum continuous discharge current.
The BMS incorporates protection and recovery functions associated with voltage, temperature, overcurrent and short-circuit limits. 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 range also supports parallel configurations 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 mobility and other energy storage systems requiring LiFePO4 technology.
The battery has an ABS enclosure with an IP65 protection rating and M6 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, the manufacturer specifies approximately 50 % state of charge, a clean, cool, dry and ventilated location, and recharging every three months.
