So I don’t have an electrical engineering background, and I’d rather not fry my Reform, so I wanted to see if these batteries would work with it: https://www.aliexpress.us/item/3256805458856945.html
They are 18650 3.2V LiFePO4 batteries, so they match the original batteries in terms of size, voltage and chemistry. However, this store 2000 mAh of energy rather than the 1800 mAh of the originals. I’m also not sure what amperage they are rated to, or what the current draw of the Reform is.
I also ordered the protected battery board, which I hope will protect these from dying the way my original batteries died (I think I let them discharge too much).
I cannot comment on your aliexpress selection but i’ve been using 2000 mAh LiFePO4 batteries from Eremit for over a year now: EREMIT 3.2V 1500mAh 18650 LiFePo4 Akku Pack
These are very similar to some cells I installed a few days ago in my Reform, from some no-name brand labelled PATOZM. Likely the same cells with slightly different labeling. So far, they’re working great.
Thanks for the feedback. I had trouble finding the JGNE cells in stock, so I’m glad to hear that other’s have had success with similar cells to the ones I found.
I purchased similar from https://www.aliexpress.com/store/1102348225 and have been happy with them:
