## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice Case If you take your time and can Solder Nice...
*by M***. on June 11, 2024*

I really have no complaints about this case and set up. The Led lights are very bright, and the charging board is very nice... This case is only as good as the Cells Used and Craftmanship of the builder. THIS IS THE ONE YOU WANT! I like these 15 Cell 18650 Kits a lot better than their 10 Cell Kits...Update: 08/19/2024 I have built 4 batteries total with only one having a very minor issue... The seller took care of it super-fast and without question... I will be purchasing 2 more soon... The charging board works really nice, and it works great in the large Milwaukee 4 battery 110v inverter... Charges and works properly...

### ⭐⭐⭐⭐⭐ Nice and heavy
*by J***. on December 6, 2024*

I like this kit! I've been getting into building lately and needed a M18 battery of larger capacity without the hefty price tag. Granted this will only be used in lights and radio but hey it works. Everything went together great. Thank you for my 6ah battery.

### ⭐⭐⭐⭐ Product is well-made, but lack of instruction
*by C***D on September 4, 2024*

This battery DIY kit for Milwaukee M 18 is a good and well-made aftermarket casing. However, you have to be in well knowledge about how the battery works. Specially, the lithium ion battery. You do need a solder and battery spot welder. PCB Circuit Board and 6 Nickel Plates, are spot on and align perfectly. Only complain that I have there’s no instruction on where the screws gonna go. It has four different sizes. You just have to play with it. Don’t expect customer service no one answers the phone or your email question inquiry. Overall, the product is pretty solid Michell you choose a good battery. Samsung or LG will get you to a comparable runtime compared to Milwaukee brand battery. Attach a picture for a sticker that I have no idea where to go don’t think they’re will have birthday fun or safety for the battery but not 100% sure.
