The BMS 3S 40A LiPo Battery Protection Board is a high-current Battery Management System designed for 3-cell (3S) lithium-ion or LiPo batteries. It ensures overcharge, over-discharge, short-circuit, and overcurrent protection — ideal for DIY battery packs, electric bikes, solar power systems, and portable electronics.
The CA-1235 Adjustable Buck Converter Module (CA1235) is a high-efficiency DC-DC step-down voltage regulator designed to convert higher DC voltages (up to 35V) to lower adjustable levels. Ideal for Arduino, Raspberry Pi, LED drivers, battery charging, and DIY power supply projects, offering precise voltage control and stable output.
