Wiring: 1. First connect the B- of the BMS to the total negative pole of the battery pack;

2.The cable starts from the thin black one connecting B-, the second red wire connects the positive pole of the first string of batteries, and the next string is connected in turn to positive pole of the battery,B-,B1,B2……B7; then insert the cable into the BMS; (The maximum number of strings is 4-7 strings, the example picture is 7 strings)
(Please weld the wires in order and avoid pseudo solder joints.)

3. Connect Charger C-/Load P- with BMS C-/P- (Use larger size wires) 4. Connect Positive Pole: Charger C+/Load P+ with Battery Pack B+ (Use larger size wires) .

2. 会社情報

Li-ion Battery Bodyguard BMS is used for Lithium ion /LiFePo4/LTO battery pack.

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

The main functions : 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.

3. よくある質問

Q: How many Ampere protection circuit boards should choose?

あ: It depends on your load power such as electric motor power please contact the sales or technical support before buying.

Q: What is the distinction between same port wiring and different port wiring?

あ: The cathode of charger and load is different for different port wiring , the cathode of charger and load is same for same port wiring and the charging current is equal to the discharge current.

Q: What is the distinction between balance and unbalance function?

あ: Equilibrium function is that high voltage cells will be discharged with resistor, waiting for the low voltage cells , to achieve the each cell voltage is consistent , to improve the battery performance for the whole group.

Q: Do you have Minimum Order Requirement (MOQ)?

あ: No, We don’t have MOQ, Different customer have different requirement ,We can provide various capacity and size is per your requirements,Also ODM / OEM is welcome.

Q: What is your term of payment?

あ: PayPal, T / T,
