Note : it is COMMOM PORT

Daly 4S 12V 80A 100A 120A 150A 200A 300A 400A 500A Li-ion Lithium Battery 18650 Charger Protection Board PCB BMS 14.8V Cell Charging Protecting Module

Model: DL4S (3.7V rated Li-ION Battery and 3.2V Rated LiFePO4) Please choose the correct model according to your batteries.Li-ion or Lifepo4

common Version : common port for charge/discharge

separate Version : separate port for charge/discharge

We can customize any PCB from 1S to 32S 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.

1. Overview

◆DL4S12V 80A 100A 120A 150A 200A 300A 400A 500A PCB is used for 4 series 12V 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 250A 300A 400A 500A, 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.
