hi all fairly new to electric bikes i have a question maybe for the experienced electric bike guys ,i have an electric bike but it does not have any battery level indicator and i need to have a rough ideal of the battery level i have seen a simple battery meter for sale on e-bay with a red/black wire connection can i just connect this directly to the battery between the switch or does it have to wire into the controller ?
would appreciate your help thanks in advance
I've done a lot of searching on Ebay and found this one, which I believe would do the job. I've ordered a couple for myself. If you want to wait a couple of weeks, I'll have the definitive answer, but I'm confident enough to risk £14.

You should be able to connect the two wires anywhere where you can get battery voltage, so the "+" can go to the controller/battery connection, directly to the battery, or to the wire in the throttle that powers the LEDs. The "-" wire can go anywhere you have 0v, i.e. battery, battery/controller connection, or the black wire that goes to the throttle.
This meter is a panel meter so you have to get a small box to mount it in because the back is open.
