XB-508 Economy
Currently Testing the Battery usage on my extreme scooters XB-508.
This is the test route of the day,
Battery is pack is composed of 3ct 19.8V LiFePO4 4.5Ah Modules.
Total current capacity is 59.4V 4.5 Ah = 267.3 watt hours.
Charged up after the test route and measured that I used 2.665Ah to do the 3.5 Mile trip.
This is giving me an efficiency of 45.69 Wh/Mile.
Giving me a total capacity of 5.909 Miles per charge at 100% discharge and 4.728 miles at %80 discharge. %80 is where we usually like to keep our packs operating.
The good news is that I have 6 more batteries on order which will give me a total of 13.5Ah @ 60V which is 810 watt hours. That is a total range of 17.7 miles @ %100 and 14.2 miles @ 80% discharge.
