Product Description

3.7V Battery pack 20S 72V E-bike Li ion battery bms 18650 BMS 30A 40A 50A 60A battery BMS Charging Voltage 54.6V With balance​Model: DL20S (3.7V rated Li-ION Battery not for 3.2V Rated LiFePO4)common Version : common port for charge/discharge separate Version : separate port for charge/dischargeWe can customize any PCB from 1S to 30S lithium batteries with different current. ​ Highlight:For the same model, its charge current is less than discharge current because Daly PCBAs were updated to well protect customer battery. Any request, Please contact us. Daly: Jan 2020 1. Overview◆DL 20S 72V 30A 40A 50A 60A bms is used for 20 series 72V battery pack.◆We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.◆The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.◆According to the customer request we can develop PCM in different sizes and structures.◆BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle serivce life time. 2. Advantage◆Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.◆Strong load ability, constant discharge current 30A 40A 50A 60A , use high voltage resistance, low innerresistance power Mosfet. The heat sink will greatly help cooling.◆IC itself has power balancing function. The circuit is simple and reliable.◆Typical voltage detection for each cell. So each battery will be prevented over charged or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load won’t affect the PCB and the battery.Temperature protection during charging and discharging.◆Extreme low power consumption. The consumption of the whole device is less than 50uA.◆PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.
