### ⭐⭐⭐⭐⭐ Battery building utopia
*by  on Reviewed in the United States 13 July 2026*

I came so close to buying a real 6ah and 12ah Milwaukee pack. My last real 12ah didn’t last 18 months.I have an e-bike which I built with Molicel P42A cells along with the spot welder I got here on Amazon. With about 50 extra cells I figured I’d try this. The design of this case is phenomenal. The cells drop in and the nickel pieces lay right in place and fit right into place thru holes on the control board. If this took 15 minutes to build I wouldn’t be exaggerating. Works perfect. Hot rid battery for under 100 bucks including the cells which will out perform the real Milwaukee cells. The 12ah case comes tomorrow. Can’t wait!

### ⭐⭐⭐⭐⭐ Good product
*by  on Reviewed in the United States 25 September 2025*

Fits perfect, functional as original. No problems.

### ⭐⭐⭐⭐ Needs better instructions
*by  on Reviewed in the United States 18 April 2026*

It’s a decent kit I wish the nickel strips were a little thicker but they will work
