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...

I've use other brands to build my own M18 battery packs. None have any instructions, including this Janllenton brand. But, this one seems to be a higher quality, with ALL the screws needed to put EVERYTHING together, such as those which hold the assembly in from the bottom, and those which hold the two clam shells together. No other kit has ever had these screw included. But this brand does. And the nickel conductors are much higher quality, full width, and fit into slots with pin hole alignment. Very well done. I like this one so much, I've just ordered two more 15-cell kits and a 10-cell kit, to use up some old 18650 batteries I scavenged. Forget the other brands, this is my new go-to brand. Minus one star for no instructions, diagrams, photos, videos, nothing! And, maybe that's for this reason: WARNING! If you do NOT KNOW what you are doing, and don't have all the necessary tools and equipment, THEN DO NOT BUY THIS OR ANY OTHER KITS LIKE IT; YOU WILL GET HURT, MAIMED, OR KILLED, AND COULD SET FIRE TO YOUR HOUSE OR APARTMENT! 18650 Lithium batteries are EXTREMELY DANGEROUS AND POWERFUL!!! You have been warned!!!6.1.23 Update: This review applies ONLY for the (15) 18650-cell battery! The 10-cell version is just like the competitors models; no wires, simple and cheap nickel cross-overs, flimsy battery cell holder. Longer and less-professional looking build!

All I needed was the outer case.. as you can see mine broke. This replacement fit perfectly. Only bought one to start with because I didn’t know how it would fit. I have two more batteries that have broken cases. So I’m going to order three more. Have one for spare.

Case is misrepresented in the photos. Cheap and not worth using. Buy one from another source. Wish I could return.

They work great, but if only replacing the top portion of the case get some nail clippers because will need to modify to make work.

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.

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?
