Description

The DIY 12V Battery Pack Case with 3S 40A BMS for 18650 Batteries provides an easy and safe solution for creating custom lithium-ion power packs. Designed for DIY enthusiasts and ebike builders, this case supports a 3S configuration (12V nominal) and integrates a Battery Management System (BMS) rated for 40A discharge current. The built-in balance circuit maintains consistent voltage across cells, extending battery life and improving safety. Constructed with a compact 150 × 85 × 25mm layout, the case allows easy assembly and secure housing for 18650 lithium cells (not included). It requires a 12.6V charger for full charging and offers enhanced safety against short circuits and overcurrent conditions. This case is ideal for applications such as ebikes, solar projects, and portable power systems, providing efficient power delivery with reliable protection. Featured By RoboticsBD.
