A few weeks ago I stated that I intended to add a 7th battery to my 2002 two seater.
This is the result. Three/four miles of extra range. Lots of acceleration. 42 MPH but limited to 38. The last 4 MPH EATS!!! range, True 22 miles range on turf mode flat ground.@ about 30 MPH
2002 2 seater 8.9 gearbox 21" diameter fat tires on 10 inch rims (205 65 10) 7.5 RFF Black Motor (My Mods) INWO Spoof. (I asked INWO to make me a modified Spoof to allow 2 more volts thru to better balance controller usage algorithm) I have the program set to 1 instead of 3 at present but it still alarms too soon. 31MDC batteries from O’Rilleys (trolling motor/sweeper batteries 105 AH.
I charge 6 with the Zivan 7th with a cheapo. The Zivan will charge 7 batteries to 85/90%
Total cost $115
