There are /is a led indicator that gives the % , but i doubt if its thrust wordy …
The odometer is not working, but i could drive about 5 hours on flat road, then start the gen and drive on whilst loading the battery’s.
The unit is mostly used for showing off
and to drive 5 km to the field for irrigating with the big sprinkler now…
Also a smaller waterpump and a submersible on board, running on battery/inverter/solar/charcoal
