LiFePO4 Battery BMS Description:
1. Protect cells and battery packs from damage;
2. Make the battery work within the appropriate voltage and temperature range;
3. Keep the battery running under suitable conditions;
4. Battery safety protection and alarm: When a fault is diagnosed, the BMS reports the fault to the system, and at the same time cuts off the circuit to protect the battery from damage;
5. Charge control: slow charge and fast charge control;

LiFePO4 Battery BMS FAQ:
Q:1. What's the delivery time for mass production?
A: Usually 3-7days, it depends on the quantity, especially function and etc. we suggest checking delivery time case by case.
Q:2. What is your MOQ?
A: 1pc is OK. small orders are also welcome.
Q:3. What is the balance function?
A: The working principle and function are as followings when your one cell voltage is up to alarm voltage(Li-ion up to 4.18V, Life Po4 up to (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will start 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 PO4 3.75V)BMS starts off power protection, all the other cells are all in the 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 the balance can not be functioning. well.
Q:4. What type of charger should I choose?
A: Lithium batteries must choose a specific charger, do not use Charger for a Lead-acid battery, for a lead-acid charger may have MOS with high-pressure breakdown protection, which will not protect against BMS overcharge. Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
