Shenzhen Li-ion Battery Bodyguard Technology Co., Limited presents the 7.4V 18650 BMS 2s5a Lithium Ion battery PCB. This BMS is designed for 2s and 3.7V Lithium Ion batteries. It comes in a vacuum-packed transport package and measures 30*9*2.2. The product is branded as LWS
Q: How do I judge what material my battery is?
A: Please check the battery body. If the normal voltage is 3.2V, it is LiFePo4. If the normal voltage is 3.6V or 3.7V, it is Li-ion or Li-polymer. You can also ask the battery manufacturer for the material.
Q: Can I use this protection circuit board for my battery?
A: To determine if you can use this protection circuit board, consider the following:
Q: Do we need cell balance or not?
A: The function of balance is to ensure consistent cell voltage after charging. As cells in a battery pack may have different performance, balance function is necessary to maintain voltage consistency.
Q: Do you have a Minimum Order Requirement (MOQ)?
A: No, we don't have an MOQ. We can provide various capacities and sizes as per your requirements. ODM/OEM is also welcome.
Q: What is your term of payment?
A: We accept PayPal, T/T, L/C, and Western Union.
We offer 1S-35S Battery BMS PCM for Lithium ion/LiFePo4/Lithium titanate (LTO) battery packs that can meet your requirements. Welcome to contact us.
