Znchgdtre Bidirectional PD Power Bank Module 6-String Battery Support Black strings 26, minimum 2 strings, max 6 10A per string, safe soldering before testing.

Supports OPO flash charging and super fast charging. Different protocols have different power levels. 65W and 100W both refer to PD protocol power, while VOOC is 20W and SCP is 22.5W. Please confirm your requirements before placing an order. Welded products are not eligible for returns or exchanges. Notes: The wires connecting the motherboard to the external battery must be to withstand 10A current, with a minimum of 1 square meter of copper wire used. Ordinary wires should use 1.5 square meters. But it cannot be fine either, as being fine may pose a safety hazard. Due to the high current at the battery end. Due to the excessive current at the battery end, it is necessary to weld the battery with a thick wire before testing, and it is not possible to use a crocodile clip to clamp the solder pad for charging and discharging testing. The motherboard comes with a protective chip that only supports 2-5 strings of batteries. For 6 strings of lithium iron phosphate, the battery needs to come with a protective board. The overcurrent protection current of the protective board must be 15A, otherwise it not work properly and may seriously damage the motherboard chip. The battery connected to this motherboard must meet the requirements and be connected in series. If your battery is a regular capacity small current single or multiple parallel connected batteries, please refer to other motherboard models.
