Extends battery life significantly
My old batteries were dying quickly due to unbalanced cells. This BMS balances them perfectly during charging. My tools run longer now, and I feel safer knowing the overheat protection is active.

Solid performance, needs careful wiring
The board works exactly as described. The protection features kicked in when I accidentally shorted a connection during testing. Just make sure you have good soldering skills; the pads are a bit small for beginners.

Good for evaluation boards
Using this for a university project on power management systems. The layout is logical for tracing circuits. Only downside is the instruction manual could be more detailed regarding max continuous current specs.

Great value for industrial projects
Bought five of these for a fleet of refurbished drills. They are robust and the voltage regulation is stable. Much cheaper than buying OEM replacement boards while offering similar reliability.

Perfect for custom tool builds
I used this board to revive some old Makita-style battery packs. The fit was precise, and the soldering points are well-labeled. It handles the current draw of my angle grinder without overheating. Highly recommended for DIY enthusiasts.

Saved my expensive battery pack
The original board in my pack failed, and this was a direct drop-in replacement. Installation took about 20 minutes. The tool runs just like new. Very satisfied with the build quality.
Q: Does this board include cell balancing functionality?
A: Yes, it features passive cell balancing to ensure all five cells in the series maintain equal voltage levels during the charging cycle, which extends the overall battery pack lifespan.
Q: Can I use this with LiFePO4 cells instead of Li-ion?
A: No, this board is specifically calibrated for Lithium-Ion (Li-ion) or Lithium-Polymer (Li-Po) chemistry with a nominal voltage of 3.6V/3.7V per cell. Using it with LiFePO4 cells may result in improper charging and safety hazards.
Q: Is this compatible with genuine Makita 18V LXT batteries?
A: Yes, this board is designed to be compatible with the form factor and connector style of Makita 18V LXT series battery packs, supporting up to 21V max charge voltage.
Q: Are the screw terminals included in the package?
A: Yes, the package includes the necessary nickel strips and screw terminals required to connect your battery cells and output wires to the board.
Q: What is the maximum continuous discharge current this board can handle?
A: This specific 5-Series model supports a continuous discharge current of up to 20A, with a peak surge capability of 40A for short durations. Please refer to the datasheet for thermal derating curves.
