Stop BMS Burnout: Makita & Bosch Battery Repair Hack
*Stop BMS Burnout: Makita & Bosch Battery Repair Hack* Sick of your tool batteries dying or BMS boards burning out under load? Today in the workshop, I’m showing you a simple, permanent fix for Chinese Makita clones and a modification for Bosch packs to ensure long-term reliability. I needed these batteries back in working order before heading back to the forest cabin at Star Russ. From simple loose wires to bypassing the discharge circuit on cheap BMS boards, these hacks will save your batteries from the bin. In this video: How to diagnose a "one-light" failure on generic Makita-style batteries. Reflowing solder on high-lead joints for better durability. The Bosch Battery Hack: Moving the output to prevent transistor/MOSFET burnout. Why "Chinese copies" are sometimes easier to repair than the originals. *Timestamps* 0:00 Intro & The Forest Build Context 1:00 Opening the Makita Clone (Torx Security Screws) 1:55 Diagnosing the "One Light" Failure 3:00 Reflowing Solder for Better Connections 5:20 Testing the Makita Repair on the Chinese Saw 6:10 Amperage Differences: 5-cell vs 10-cell Packs 7:00 Bosch Battery Modification (The BMS Hack) 7:45 Why BMS Boards Burn Out & How to Fix It 9:40 Soldering the Output Directly to the Pack 11:50 Multimeter Testing: 16V Output Check 13:40 Final Assembly & Drill Test 14:10 Closing Thoughts & Next Cabin Update If you're building off-grid or just trying to save money on power tools, I hope this helps you keep your gear running longer.
