7S-24V-Li-ion-BMS-3.7V (Battery Management System) protection board for lithium-ion batteries.
Application: Designed for 7-series lithium-ion battery packs with a nominal voltage of 24V and individual V.
Functionality: It's a common port for both charging and discharging, with a maximum discharge current of less than 150a
Connections: "C-" connects to the charge and discharge negative pole, while "B-" connects to the negative pole of the battery pack.
Features: BMS boards like this typically offer protection against overcharge, over-discharge, overcurrent, and short circuits, and some may include balancing and temperature protection.
