I make a wireless battery pack using the Qi standard for my Fluke 123, but this should work for most scopemeters. This makes charging easier, but is not a permanent solution as the Fluke continuously runs while "off" thus charging never terminates (and the battery doesn't stay charged). Let me know what you think and how it could be improved.
Source of parts:
I bought a cheap Qi reciever, for a couple of dollars:

I would use this board in future as it has a controllable step-up voltage, and nicer parts:

Then you just need a 18650 cell, but buy branded from a good supplier as there is a lot of fakes out there.
