Daly 3.2V LifePo4 16S 48V 80A 100A 120A 150A18650 BMS battery protection board with balanced lithiumion lithium battery module

Model: DL16S

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

DL16S48V80A/100/120/150A/200A PCB is used for 16 series 48V LiFePO4 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/100/120/150A/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.

FQA
1.What is the common port and separate port? what is the difference?
We take 13S48V16A BMS as an example, common port 16A means your charge cathode and discharge cathode are connected in the same point end(our P-), charge cathode and discharge cathode are used in the common connection 
port, so the charge current and discharge current are the same 16A. while the separate port is separately connected by charge cathode (C-) and discharge cathode (P-),  so the charge current and discharge current are different, discharge current 16A, charge current 8A.
 
2.What is the balance function?
The working principle and function are as followings, when your one cell voltage is upto alarm voltage(Li-ion upto 4.18V, Life Po4 upto (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will starts a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po43.6V)are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage(Li-ion 4.25V, Life Po43.75V)BMS starts off power protection, all the other cells 
are all in stop of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then balance can not be functionning.
well
 
3.The relationship between Battery capacity and BMS current?
There is no direct relationship between  Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.
 
4. What type of charger should  I choose?
Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge.Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
 
5. What current BMS should I choose ?
Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 16A for below 350W, 25A for below500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one inall, continue current shall be higher than current limitation in Controller.
 
6. Whether my BMS damaged?
if you want to judge if the BMS is damaged, please take the folowing steps, to test if each cell voltage is the same with voltmeter? if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the 
start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displyed as no charge, no discharge, no discharge while the battery has voltage.
