19.2V NIMH battery rebiuld with 18650?

[jacekripper]

Hi all.
I have 14 years old impact gun Ingersoll Rand - absolutely brilliant and powerfull - and batteries are dead obviosuly. Seen some YT videos and decided go for it. I have many 18650 batteries kicking around and easiest way would be connect 5 in series, 5S BMS on top - job done... But! Can I put in another slot of 5 in series, (plenty space inside housing) another 5S BMS on top and connect both units paralel? Is it good idea, or is out there somwhere better way?

Yeah you can do that no problem, same voltage more amp hours

I like these projects
I did rebuild a lot of older machines and replaced them with the newer 18650 battery type.

I use the battery's of dead laptop battery's and test the capacity and re-use them into other equipment.
This is a cheap way to bring new life to older equipment.
