The 2S 8A Li-Ion BMS Protection Board is designed for two-cell-series lithium-ion battery packs. It provides a 7.4V nominal battery voltage, requires an 8.4V charging voltage, and supports up to 8A continuous operating current. Protection functions include overcharge, over-discharge, overcurrent and short-circuit protection.
Full Description
The 2S 8A Li-Ion Battery BMS Protection Board is designed to protect and manage lithium-ion battery packs configured as 2S, with two cell groups connected in series.
A typical 2S Li-Ion pack has a 7.4V nominal voltage and reaches 8.4V when fully charged. The board supports up to 8A continuous current, with protection against overcharge, over-discharge, overcurrent and short-circuit conditions.
This type of BMS is commonly used with 18650 Li-Ion cells and other compatible lithium-ion cells.
Important: This is a battery protection/BMS board, not a charger. An appropriate 8.4V charger or CC/CV charging source should be used for a 2S Li-Ion pack.
