Overview 📝
The 4S 10A BMS (Battery Management System) is a critical component for anyone building a 4-cell Lithium-Ion battery pack . This specific unit is a pre-owned/salvaged module that has been rigorously tested to ensure all protection circuits are functional. It is perfect for DIY power banks, small 12V-16V motor projects, and portable electronics where high-end new components aren’t necessary, but safety is still a priority.
Key Features ✨
Triple Protection: Safeguards your expensive 18650 cells against over-charging, over-discharging, and short circuits.
10A Current Capability: Supports a continuous discharge current of up to 10 A, suitable for LEDs, small routers, and mini-drills.
Compact Design: Fits easily into battery enclosures or custom 3D-printed cases.
Pre-Tested Reliability: Every “Used” board at Robochacha is checked for voltage throughput before shipping.
