RadRover long range configuration 60v 41.5Ah

[JTK77]

Just added this quick release 60v 17.5Ah range extender to go with the 60v 24Ah main battery.
Rarely need the weight of full 60v 41.5Ah capacity on my Rad but when needed its mounted fast.
Alltogether straight 24 hours of PAS in 100w setting...so very long range
The bike has now working regen but the purpose for that is other than range increase.

Was that 24 hours of riding or elapsed time? I'm thinking perhaps you were referencing elapsed time after a long day of riding.

I was getting about 15mph when I did my 9-5 battery burndown ride in PAS 1 at 100w. At a similar drain/speed if you rode 24 hours it would be 360 miles. Factor out the extender and that's still over 200 miles on the stock Rad battery.

Calculated range based on recorder Wh/mile. No time for 24h ride experiment
Stock battery would last ~6-7h
This setup 24h.

Are you using these batteries in a parallel or series connection? Too many questions... Are you still using the standard RadPower 750w hub motor? Are you using the DATEX devices? Or just A or B?
Thank you!

These batteries are used fully separately for long range only so not parallel or series. Rack is installed in about 2 minutes.
Did some range testing (Wh/mile) last week.
On representative 34.7 mile route (mixed terrain) with average speed of 17.9mph I got power consumption of 406wh or 11.7wh/mile. Considering quite aggressive knobby tyres I'm pleased.
Now with full batteries 2400wh (net) this equals 205 miles at 17.9mph average speed. Propably won't be doing distances like this in one day though.

Did a little road trip last sunday with this setup.
Did some road side repairs, had some pizza and did some coffee stops. Used about 2.1kwh on my 77 Mile trip so 27.3wh/mile. Had average speed of 20.7mph. Mostly when I had open road ahead kept the speed between 23-28 mph. Total battery capacity is 2400wh so at this pace total range would be 88 miles. Dropping the open road speed from ~25 to 20mph would more than double the range to ~200miles.
