【20S45A】☆☆☆20S 72V 45A 18650 Lithium Battery BMS PCB Protection Board with Balance for Scooter Ebike Electric Bicycle☆☆☆ ✔With a balanced, same port 45A discharge.✔Protection board with overcharge protection, over discharge protection, over current protection, short circuit protection, temperature protection.
【Attention when connecting】✔In order to achieve the best BMS performance and to run the longest distance, the whole battery must be matched well (each battery voltage <0.05V, IR<15mΩ, capacity<30mAh) to ensure the best consistency of the battery.✔The cell must be connected in parallel first, then connected in series
【Order of connection】✔Step1: Connect charging /discharging wire , battery pack negative wire✔Step2:After confirm the wires are connected OK, plug the connector cable in the BMS✔DO NOT plug CONNECTOR CABLE in the BMS before connect wire!!
