Testing voltage on OEM THPlus batteries

[weajr]

Anyone have a way to quick test voltage on these things, Pins outs to hook a Volt meter to would be nice.

It will be like this, with mini Deans (flat bladed) contacts where the round contacts are.


At full charge each cell should measure 4.35VDC for a total voltage on the outside contacts of 17.4VDC.

I bought a tester from Terrestrial Imaging that I like. It doesn’t measure each cell individually just total voltage. It fits in the palm of your hand.

Thanks but no thanks, I have a THPlus, that is not a pic of one of its batteries

I have been "resetting" Li-ion batteries on my Dewalt and other power tools

Good Battery Wont charge Battery
Wire positive to Positive
Wire Negative to Negative (only for a few seconds)

Drop the former "ded" one back in the charge, works as planned

Anyone try that with the Yuneec batteries?
