BL1830B 18V 3Ah Battery Protection Circuit Board & Nickel Sheet
BL1830B 18V 3Ah Battery Charging Protection Circuit Board with Nickel Sheet
Keep your 18V power tool batteries running safely and efficiently with this purpose-built BL1830B Charging Protection Circuit Board. Designed as a direct replacement or upgrade board for 18V 3Ah nickel-based battery packs, this PCB features dual integrated circuits (ICs) that continuously monitor the voltage of each individual battery cell — helping prevent overcharge, over-discharge, and short-circuit events that can shorten battery life.
Whether you're rebuilding a worn-out battery pack for a torque wrench, drill, or angle grinder, this circuit board delivers dependable protection and precise voltage monitoring in a compact, easy-to-install form factor.
Key Features
- Dual IC Cell Voltage Monitoring: Built-in dual ICs independently detect and balance the voltage of each battery cell for consistent, reliable performance.
- Overcharge & Over-Discharge Protection: Automatically cuts off charging or discharging when voltage thresholds are exceeded, extending overall battery pack lifespan.
- Short-Circuit Protection: Integrated safeguard helps protect your tools and battery pack from damage caused by accidental short circuits.
- Nickel Sheet Included: Comes with nickel strip/sheet for direct spot-welding to battery cells — no need to source additional components.
- Compatible Rating: 18V / 3Ah battery configuration — compatible with BL1830B-style pack rebuilds for torque wrenches, drills, and angle grinders.
- Durable Construction: Made from resin and metal components built to withstand the demands of regular workshop use.
- Multiple Color Options: Available in 3 color options to suit your preference.
