Restore reliable runtime to worn 18V lithium-ion power tool batteries with this direct-compatible charging protection board. Engineered specifically to fit Makita BL1830, BL1840, BL1850, and BL1860 battery chassis, this copper-clad laminate circuit replaces degraded factory boards that cause voltage drops, sudden shutdowns, or unresponsive tool triggers. By actively balancing current flow and enforcing strict thermal boundaries, it prevents dangerous overheating while keeping every cell group within safe operating limits. Ideal for electricians, makers, and maintenance technicians who prefer refurbishing existing packs rather than purchasing costly OEM replacements.

Benefits & Practical Application Tips

  • Extends pack longevity by maintaining consistent voltage delivery during heavy-duty grinding, drilling, or impact applications.
  • Integrates seamlessly into standard 5-string Li-ion layouts for predictable 3.0Ah capacity management.
  • Ensure pins align flush with the battery contacts after soldering to prevent arcing, and store spare boards in anti-static bags to preserve terminal integrity.

Technical Specifications

  • Board Composition: Copper-clad laminate substrate
  • System Voltage: 18V DC (Li-ion chemistry)
  • Nominal Capacity Handling: 3.0Ah across 5-series configuration
  • Max Charging Current: ≤12A
  • Overcharge Safeguard: 4.25V cutoff with 2-second verification delay
  • Under-voltage Lockout: Triggers at 14V to protect cells
  • Thermal Management: Disengages charge/discharge at 100 °C, resumes at 85 °C

Package includes:

  • Lithium Battery PCB Board (available as 1, 2, or 5 units based on selected option)

Operational Reminders

This circuit is designed exclusively for DIY electrical refurbishment and professional battery restoration. Verify your battery housing dimensions and pin layout matches the original manufacturer template before proceeding. Use insulated tools and work only on discharged packs to avoid short circuits. Store unused units away from moisture and extreme humidity.
