Question How to service the Orcatorch or Nitesun battery canister?

[rjack321]

No sure the average person should start chiseling lithium batteries...

But then again we are not attempting an average repair.

If its possibly glued in... I might get an old toaster oven, OUTSIDE and warm up the whole pack and see if you can get it free...
Maybe strategically drill a hole at the opposite end to help push them out with a pin.

I assume it's a plastic housing?

Are they in series or parallel?

It's pretty normal for stuff like this to be embedded in potting compound which is like a weak epoxy. The OP won't be pushing or pulling them out of the housing until the majority of that potting compound is removed. If the OP jabs it with a soldering iron that usually makes it brittle and it can be chipped out with a dental pick. Of course that runs the risk of shorting something which would be bad. But that's the breaks when working on stuff like this.

At 7.4V the are 2 series with the rest of the bundles paralleled.

All of this is probably more effort than an Orcatorch is worth TBH.
