Model NO.-Daly 4S BMS
Type-LFP
Voltage-12.8V AMP-100A
Remarks-Daly Waterproof BMS
Balancing-Yes
Additional Information The main functions are: overcharge protection, over-discharge protection, over current protection, short-circuit protection, temperature protection etc.

Strong load ability, constant discharge current 80A/100A, use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help to cool. IC itself has a 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. A Longtime 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.

BMS (3.2V Rated LiFePO4 Battery,

Common Version : common port for charge/discharge 

Separate Version : separate port for charge/discharge

We can customize any PCB from 3S to 32S lithium batteries with different current.

1. Overview

1.We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.

2.The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc.

3.According to the customer request we can develop PCM in different sizes and structures.

4.BMS manufactured by high quality MOS and IC imported. Keep your battery long cycle serivce life time.

2. Advantage

1.Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko of Japan.

2.Strong load ability, constant discharge current 25/35A/45A/60A , use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling.

3.IC itself has power balancing function. The circuit is simple and reliable.

4.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.

5.Extreme low power consumption. The consumption of the whole device is less than 50uA.

6.PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating

Description4S 10A 12.8V 32650 Lithium battery protection and charger BMS Module
This BMS is commonly used in making battery pack for EV and Solar application and also perform very well in under extreme conditions. The temperature sensor is used to monitor battery temperature. Temperature is important, because charging (of most lithium-based cells) is not permitted below freezing temperature and usually above 45°C.

Features:
1) High-accuracy voltage detection circuit.
2) terminal of the charger using a high voltage device.
3) MOS transistor can control the battery charge and discharge.
4) low standby current consumption.
5) Use Lithium ion batteries of 32650 size and of EV and Solar Grades.
6) Battery Pack Output  12.8V (4S Type).
7) Deep Discharge & Over Charging Protection.
8) Comes with Temperature Sensor.
