    How many miles left ?

    Hi, hypothetical question because I don’t want to run the battery until it stops.

    I charge my 19.2ah 52v battery to 90% which is 56.7v. We did a 16 mile ride over a rolling course and that brought the pack down to 80% (55.4). Then yesterday did 48 miles which has left 49.6v in the battery. Given a rolling terrain and our light use of power (just taking the edge off hills) how much mileage could we reasonably expect from this point? We have a Bafang BBS02 750 watt motor.

    My estimate if you ran the battery right down to 42V would be 100 mi or pehaps a bit more IN TOTAL. The last few miles will not be great performance-wise. In case you haven't seen the 52V version of this chart, I am attaching it. Click image for larger version  Name:	52V Charge Levels.png Views:	0 Size:	41.9 KB ID:	151398
