Review: Great value. - As a residential electrician, I primarily use milwaukee 5 ah m18 batteries. I saved one with a fried circuit board and a bunch of 18650 cells from other batteries that stopped working. I used the circuit board to fix one battery successfully. The only weird behavior is when heavily using a power tool, the safety stop feature stops it for multiple seconds, then I push the power indicator button, it shows the bars left and works again. With the case and 18650 cell kit (I provided 'old' cells, fully charged before install.) I didn't read any directions. I spot welded and soldered a few spots, found pics of battery layout in harness on Google. I connected an old 5 ah m18 circuit board, from a battery that stopped working properly from 2 failed 18650 cells, used the battery housing in this kit. In conclusion, this kit gave me back two milwaukee 5ah batteries, from the grave. After using the batteries remade from this kit for a few drilling experiments, they seem to work great, besides the aforementioned seconds long overload stop and restart in the salvaged battery with the circuit board from this kit, which isn't a big deal, and probably protects everything more than without the seconds long stop.
Review: Milwaukee xc 5.0 4.0 battery replacement case(China replica only option works good) - I own a garage and milwaukee is my go to tool and proven to outlast all other power tools hands down. Only downfall is I use the 1/2 1200 ft # impact daily on wheels. The vibration is hard on batteries cracking the cases after years of use. Milwaukee will not sell the m18 battery cases so the xc 5.0 4.0 batteries become useless once the cases fail. The 18650 batteries were still good after 3 years. So as bad as I hate CHINA made anything I purchased these plastic housings. Overall they seem like decent quality replicas of the milwaukee xc 5.0 4.0 battery packs minus batteries. It's actually a kit to build your own battery packs. The only issue is there are small plastic tabs on the top part of the battery case that must be trimmed as they keep the case from fitting snuggly on top the battery pack. I used a utility knife(I included pics with the tabs trimmed circled in color for better understanding) and took the blade straight down on the tabs from the top of the new case and they popped off once trimmed. Lot of people on here giving bad reviews because you have to spend 1 minute trimming is ridiculous. After trimming the top part of the new case the old battery pack assembly fit perfect and they include new Phillip screws so you don't have to reuse the old safety torx screws. This is an excellent replacement case for the xc 5.0 battery pack that requires 1 minute of trimming. This is the only replacement case I could find. Man up boys & girls and do some trimming. It's easy as hell and saves buying a new $100 battery pack.
