Everybody should learn to solder and desolder anyway. It is much less expensive to assemble these types of batteries from kits. PC boards do sometimes need to be replaced. Saves tons of money over buying new batteries when only a small internal component is needed instead. ### ⭐⭐ 2.0 out of 5 stars Didn’t work *by S***. on Reviewed in the United States on April 15, 2024* Tried using but didn’t work so I just replaced the battery ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Battery control module *by A***R on Reviewed in the United States on May 9, 2024* Awesome price fast shipping ## Frequently Bought Together - Janllenton 18V 10-Cells 21700 PCB Battery Charging Protection Circuit Board for Milwaukee M18 6.0 Ah, 8.0 Ah Battery packs (Pack of 2) - Lesnow solder wick braid 10ft Length Desoldering Wick Braid Remover Tool Solder Sucker 1 piece No-Clean soldering Wick Wire Roll and Disassemble Electrical Components - Thermaltronics TMT-TC-2 Lead Free Tip Tinner (20g) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/592447971-protection-circuit-board-pcb-for-milwaukee-m18-18v-replacement-bms](https://www.desertcart.sk/products/592447971-protection-circuit-board-pcb-for-milwaukee-m18-18v-replacement-bms) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-19*
