good info, thanks  ;D

will two of these batteries fit side-by-side in an MHS saber?

But there is a way to make it work.  But it is not as cut and dry as ordering parts.

I cut windows in a MHS Ribbed extension to fit an 18650 dual pack.  Then the battery slot was covered up with a sink tube overlay.   ;) Worked great.  I have a commission formulating in my head using the same idea.  If you choose to pursue this route bear in mind that you must leave enough sink tube-MHS piece overlap so that you can't see the battery.  I want to make it less noticeable by using a grenade section powder coated after being modified.  As well as a black 18650 pack.

Good luck.

The only prob I found w/ this method is, if you heat up the neg terminal too long it can desolder the legs on the components of the existing protection board. and I had sanded the coating off and used flux.

happened to me on my latest saber, luckily I had ordered a 7.2 pcb not knowing the cells were already protected, so I took the cells apart and removed the existing PCBs and built them back up w/ the 7.2 board.

but I have a saber from Eastern that Im sure he used this method on and they work perfectly.

Nice tutorial! I'm planning on building my first saber sometime in spring next year, but there are some things I'm still considering like: Would it be possible to set-up a pack like this one (in-line instead of side by side) in a MHS-hilt, including a soundboard (i.e. PC or Obsidian USB)?

I'm starting to get a pyramid of 18650 Li-Ion batteries on my work bench. Funny thing is, they keep tossing old laptop battery packs into the repo-depot  pile at work. I grab them up and recycle. Usually I'll find a bad or diminished cell inside, either toss it or set it aside. The rest of the cells work fine.

At this rate, I'll be able to build a Li-Ion power motorcycle soon..

P.S. What is the charge time on 50 Li-Ion cells in series?  ;D
