Products Description
Cheap Price 7S 29.4V 10A Cycle Mobility Scooters Electric Motor 24V Lithium Li-ion Black Battery Charger For 24V Battery Pack
Advantages
1)Dual color LED indicator:Red means Charing,Green means full charged.With 1 year warranty.
2)Constant current, constant pressure dual scheme design, perfectly conform to the lithium battery charging characteristics.
3)The two way average flow scheme is used, when one of them is damaged, only the charging current is reduced by half, and it can be used.
4)The charging time is adjustable, with LED indication, precision voltage and current detection, effectively preventing overcharge and completely eliminating charge of discontent and so on.
5)The input and output lines use high quality wires, corrosion resistance, and no cracking.
6)The shell is PC industrial raw material, fire retardant and flame retardant, temperature resistance 75 C.
7)With output short circuit protection, even if the output short circuit will not damage the power supply, when the output short circuit release, the power supply is still normal output.
8)It has the function of soft start, can withstand frequent switch start, will not cause damage to the power supply.
9)The enclosure with a fixed installation hole, with a terminal, the input and output connection is extremely simple, no need to use a soldering iron.
10)The DC current is precise IC control, non single triode constant current. Each cycle is monitored and the current limiting circuit is designed to prevent charge current from being too high, protect battery and extend battery life.

FAQ
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 connectionport, 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 0.1V, the fault is displayed that it cannot run far, no power supply at thestart 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.
2.What is the balance function?
