2S 8A 7.4V/8.4V 18650 Lithium Battery BMS Protection Board | Li-ion/Lipo Charger PCB

The 2S 8A Lithium Battery Protection Board (BMS) is designed to keep your 18650 Li-ion or LiPo battery packs safe and long-lasting. It ensures stable charging, discharging, and prevents damage from electrical faults. Ideal for DIY projects, robotics, and custom battery packs.

Frequently Asked Questions (FAQs):

Q1: What does a 2S BMS mean?
A 2S BMS is designed for a 2-cell (series) lithium battery pack with a nominal voltage of 7.4V and a full charge voltage of 8.4V.

Q2: Can I use this BMS for both Li-ion and LiPo cells?
Yes, this module supports 18650 Li-ion as well as LiPo battery packs within the 2S configuration.

Q3: What happens if I connect more than 2 cells?
This board is strictly for 2S packs only. Using it for more cells will damage the BMS and battery.

Q4: Why is a BMS necessary for DIY battery packs?
A BMS ensures safety and efficiency by balancing charging, preventing overheating, and protecting your batteries from overcurrent or short circuits.
