Hoping this is the correct forum, seemed to be from searching.
I'm looking to replace the cells in the battery pack for my Trend Airshield Pro respirator.
I found this how to where someone replaced the cells in his battery with new NIMH cells, but I want to upgrade to lithium ions for higher capacity.
I have three spare Olight 18650 3.6v 3600mAh batteries, and they seem like the perfect choice for this project because of the various protection circuits they're advertised to have.
I've never replaced cells in a pack like this before, so I have several questions:
If anyone is in the DC area and is able to help out by letting me use your welder or with other advice, please let me know as well.
Thanks for the help!

I've never replaced cells in a pack like this before, so I have several questions:
- Can I use the existing charger with these new cells? If not, can I use the existing barrel plug with a compatible AC charger?
- Do I need to add a Battery Management System or anything else to the pack besides new cells?
- I assume I need to use a spot welder and not try soldering to connect the cells together, right?
