FeedbackLoop | #58 - Fluke 97 ScopeMeter battery upgrade to Li-ion @feedback-loop | Uploaded 7 years ago | Updated 23 hours ago
I got this meter quite cheap with no accessories and no battery pack. Replacement Ni-CD and NI-MH packs are sold for $20-30, but, instead of spending money on obsolete technology, I decided to figure out if I can use Li-ion cells to build a pack for free. I have plenty of various used cells salvaged from laptop packs and such. It turned out that it is easy to use 2-cell Li-ion packs in this meter. Such configuration is not perfect, but works fine. I ended up adding a battery management module for about $3 for extra safety and, hopefully, longer life of the pack.
