Ok guys we’re trying to get a handle on our current battery situation and we have found that the voltage readings don’t make a whole lot of sense (to us).
We bought this 2007 E2 with Ride-4-Fun motor, controller, 14" wheels and we think everything else Ride-4-Fun offers.
The batteries are lead acid and we started out on a full charge 76+ volts and recalibrated our SOC display meter. On our little ride around the neighborhood it was mostly flat but we did encounter a few pretty steep hills we barely made it to the top of (especially one we thought we was gonna have to roll back down the hill lol).
After 2 miles the meter was down one bar
After 2.6 miles it was down two bars
At 4.4 miles we were down three bars
Then at 7.3 miles it went straight to the red bar so we checked the voltage and it was 73.1 volts
According to the information we used to make this chart
we should have been close to 60% capacity still which to us means that we still have over a half a tank so we went around again (slowly on a fairly level trip) and after another 1.5 miles it still read 73.1 volts.
The turtle came on after the red bar some time and it would go away if we turned it off like to check the volts and it would show up every once in a while after that.
Another issue we have noticed is that the speedometer is pretty accurate according to our GPS at low speed but not as accurate when we go faster. The odometer at 2 miles (according to Google map) registers 1.5 miles. We don’t know if the difference is in the odometer, the motor pick up magnet, the gear ratio, the 14" tire size or what. ???
We want to get GEL batteries and a BattSix monitor but are reluctant to do so until we know what and where all our problems are.
