The problem with using an analogue meter is that if it's scaled for 25A
(which I need) small currents such as 2A hardly move the needle.

The only slight snag I have found using a clamp meter with a hall efect
sensor is that they are slightly affected by the position of the wire
inside the loop.

There will also be a constant small drain on the battery to run the
electronics.

As a bonus, the percentage reading is usually wildly inaccurate, so you
need to go by the voltage and accumualted amp hours readings..


Thanks for that. Helpful!
