General description This Li-Ion Battery Case is designed specifically for the Zhipu No Original 18V Lithium Battery. It features a built-in IC that detects cell voltage and current, while also keeping track of the number of uses. The case includes multiple safety protections such as overheat, overvoltage, undervoltage, overcurrent, and overcharge protection. It is suitable for use with various power tool manufacturers and is intended for those with experience in battery assembly. Technical specifications Type: 10-Hole Color: Black Material: Plastic Measurement allowed error: +/- 1-3 cm Installation This product is a component without a battery core and is used to repair and assemble battery packs. For new cores, ensure that: (a) 18650 power lithium battery cores are used; (b) A group of six cores must be equipped with resistance and capacitance to equalize their voltage. If repairing an old battery, test the voltage at both ends of each cell and charge them to the same voltage if they
