It can also be used when you are trying to charge a troublesome battery. If the watt meter display cuts out with the bike then the problem is with the battery. If the watt meter display is still on when the motor cuts out then the problem is with the controller or the motor. ![]() If your drive unit is shutting off just hang a watt meter in between the battery and the controller. Having a watt meter is not only a cheap way to tell exactly how many Ah your e-bike has burned up, it also can be used for troubleshooting purposes. If you plug this meter into a 70v Nominal pack it will stop working forever. Both meters max out at 60v so do not use them on any packs that are higher than 52v nominal as they could be more than 60 when fresh off the charger. I have been very pleased with the performance of this watt meter and although it looks like it may be made by the same manufacturer, the display is much higher quality and much brighter than the ebay one. Recently I purchased and have been using a $30 150 Amp watt meter from located here which has XT90 connectors on both sides (one male and one female) along with one extra male
