1. Built-in IC detects mobile voltage current. And hold in intellect the diversity of uses! 2. Detection and defense battery:Overheat protection, overvoltage protection, undervoltage protection, overcurrent protection, overcharge protection. 3. all the new collection of achieve low voltage shutdown. Cooperate with many factories! 4. PCB design may possibly alternative because of modifications within the shipping chain and processing technology. 5. Suit for Zhipu Hongsong Jingmi (no Original ) 18V Lithium Battery; note: This product is component without battery core. It is used to repair and construct batteries pack, people who find themselves acquainted with battery functionality and feature real looking trip in battery assembly. Preparation before assembly: 1. If a fresh core is used, please note: (a). 18650 power lithium battery core must be ; (b). A organization of six cores ought to be geared up with resistance and capacitance to make their voltage the same. 2. If the old battery is repaired, please verify the voltage at both ends of each cell. If the voltage is different, please fee every single cellular to an analogous voltage value. Very important: that the voltage of every cellular is an analogous before welding PCB. Specifications: 15-Hole colour: black Material: plastic Package Contents: 1 set x Battery Case Due to Different manufacturing batches, Some kit have different colors and appearances, yet have a matching operate Only the above package content, assorted merchandise are not included. Note: Light and various exhibits may cause the colour of the item within the photo a bit diverse from the real thing. The length allowed error is +/- 1-3cm.
