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……B6; then insert the cable into the BMS;
(The maximum number of strings is 4-7 strings, the example picture is 6 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. Company Information
|
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. |

Advantage: Use top quality (A-level) protective integrated circuit IC, from the solution of Seiko,Ricoh, MM, HY…και τα λοιπά. Strong load ability, constant discharge current 5A/20A/35A/60A/100A/200A/350A , 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. |
3. FAQ
|
Q: How many Ampere protection circuit boards should choose? ΕΝΑ: 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? ΕΝΑ: 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? ΕΝΑ: 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)? ΕΝΑ: Οχι, 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? ΕΝΑ: PayPal, T/T, |
