❓ Frequently Asked Questions (FAQs)
- What does 2S 3A BMS mean?
“2S” indicates it’s designed for two lithium cells connected in series, resulting in a nominal voltage of 7.4V and a full charge of 8.4V. “3A” refers to its maximum continuous discharge current capacity. BMS stands for Battery Management System, which protects the battery. - How do I connect the 2S 3A BMS to my batteries?
You need to connect B- to the negative terminal of the first cell, B1 between cell 1 positive and cell 2 negative, and B+ to the positive terminal of the second cell. P- and P+ are for the load/charger connections. Always refer to a wiring diagram (we recommend checking the video section!). - Can I use this module for 3.7V LiPo batteries?
Yes, this module is compatible with both 3.7V nominal Li-ion (like 18650 cells) and LiPo batteries, as long as they are arranged in a 2S configuration (two cells in series). The crucial part is the 2S setup for 7.4V/8.4V. - What is the price of 2S 3A BMS in Bangladesh?
