I'm working on a 3d printed housing to replace the standard cells with 18650 li ion batteries. Looks like I'll be able to fit two in series and then use a buck converter to buck the voltage down the 5v.
Maybe just use lithium USB-power bank, which delivers exactly 5 V which is the voltage of a loaded NiMh accupack for Fluke 123. If the power bank doesnt fit into battery cabinet it can also be attached to the stand foot outside and cable can feed to inside.
@@electricalautomation I think you are mistaken! I not ment the power supply, this is 10 to 20 V, yes. I mean the battery connector inside battery cabinet at back. Remove old battery and install USB-plug. Then connect Li-Ion-Power bank for USB, which delivers regulated 5 V. This voltage is same as a charged Fluke battery! This way you can extend runtime to days propably.

Looking forward to your 3D printed housing. Great idea
Very interesting Video. Have question: Can I use power supply from Fluke 97 to charge Fluke 190-202. Thank you very much.
For Fluke 190, I would recommend using Fluke requires BC190 as the power adapter.

Thanks for your comments, but just note that the voltage of the power bank has to be 10 - 20v DC, as displayed at 2:45.

@@johnbiden2834 Thank you very much for the idea, is there a particular brand that you recommend o model that you used. Appreciate it very much.
