Thanks I've looked at a video and it seems to make sense how to measure current:
I do not want to disassemble my bike just to measure current.
Is it possible to put my voltmeter in series with my battery? It's 60v. Then I can just turn on the light. I'm a bit concerned of spark when I'd use the 2 probe to close the circuit
You only need to insert the shunt (the big rectangular thingy with two bolts) in the POS battery lead. The meter can be wired "on", with the backlight turned off where it then draws insignificant current. You turn the backlight on/off by momentarily pressing that one-and-only 'set button' If you disconnect the battery the meter remembers the watts- The reason why I use this meter!
I left a meter connected to a 5A battery for over a year and the battery still needed no recharge (sez something about lithium self discharge
And as said before, the voltmeter portion is as accurate, or more so than most other small meters
of similar types. That is- once you set the shunt for the one you have lol
Do note that this meter is NOT waterproof.
I build them into my battery cases which is why I have so many.
