This is a video does a deep dive in showing how the Battery Grinspector is used setup and configured for testing an ebike battery pack. Unlike other all-in-one test devices, the Grinspector is not an active piece of power electronics and requires that you hook up an external load and external charger in order for it to function as we detail here.
The benefit of this approach is that it allows operation at voltages and current levels that are much more representative of actual ebike systems than the self contained testers you see for R/C packs. Our 2020 Grinspector model can test batteries up to 100V and at discharge currents up to 35 amps provided that you have a suitable load resistor.
We developed this device for in-house use primarily but decided to make it into a product mostly geared for ebike shops and service/repair centers. With so many more electric bicycles on the road and so many ebike batteries that are in a questionable state, we’re hoping that this tool allows more people to make informed decisions about their battery situation.
