Product Description :

Daly 20S 72V Li-ion BMS 80A 100A 120A 150A 200A Big Current for 18650 Lithium Ion Battery Pack for lithium battery

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/discharge

We can customize any PCB from 1S to 30S lithium batteries with different current.


1. Overview

DL 20S 72V 80A 100A 120A 150A 200A PCB 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 80A 100A 120A 150A 200A, use high voltage resistance, low inner

resistance 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.
