Hello friends!! I have a theragun massager. The company no longer sells replacement batteries. They told me I should buy a new device. Yeah sure!! When I opened the battery pack I found that it has 3 batteries Samsung INR18650-20R batteries.
My question is: what batteries should I buy to improve the use time of the device and that it still works well?

any of these options?

Thanks a lot
Alejandro

This is probably dependent on pricing as well - I would think the INR18650-29E would be a minor upgrade and probably not much more than the INR18650-20R's.

You could go to the higher capacity cells, but I am not sure if there will be much benefit given for runtime.

You need Q/R/RMs. E and G won't do the discharge current needed.

25Rs are in plenty of supply.

25r is a safe bet.
btw that looks like a very common tool pack.
lots of brands with only key tabs to differentiate.
easy to fix with a dremel.
