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).
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.
