18V 15-Cell 18650 Battery Replacement Case for Milwaukee M18 48-11-1890 - DIY Repair Kit for 9.0Ah Batteries (Battery Not Included)

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...

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.

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.

Internals worked with original battery.

Performance, freedom, and savings: it is simply a relief to be able to build your own M series batteries!!! One hell of a money saver too!!!!! Order millions of these along with a good-quality lithium 18650 ir 21700 style cells (I hope that I got these numbers right). You will feel very good saving money.

How can i get wiring diagrams?Yes it’s easy for all part but how about two wires red and blackWhere can I connecting them?

I hope my pictures help with clearing up how to connect the black and red wires that came with it as it did not have instructions or clear way of putting in the batteries. I had to watch a video on youtube to see how someone else installed the battery. I had soldered the piece before I installed the wires which you should do the opposite. The cables go underneath the board as if you place the wires above then it would not close the battery block. I had a bunch of spare new 18650 batteries from the vape days so getting this works perfect for me as I can buy a ryobi converter then it would work with this setup and now I have an extra 18v around.

The housing feel alright. It takes a while to assembly the battery pack thou. Once you get into it. I will love it.
