Re: 2007 ezgo series - new purchase
Welcome to BGW!
Unlike a PDS carts, series carts are not speed limited by the controller to about 20MPH going downhill.
(That's in the Freedom mode, max downhill speed is lower in the other PDS modes)
PDS carts with aftermarket controllers that eliminate regen braking share the downhill runaway problem with series carts.
Since PDS controllers also limit top speed on level ground, they tend to have a more consistent speeds on inclines.
Of course, once the controller is allowing the motor to draw all available amps, a PDS cart will slow down on an incline like a series cart does.
Your statement that you've driven daily for four days without recharging, is troubling.
Lead-acid batteries have no memory, so they do not have to be discharged to some arbitrary point before recharging.
In fact, the opposite is true. The higher the average State of Charge maintained, the longer the battery's life expectancy.
If you don't already have them, here is a Voltage vs SoC chart, and a SoC vs Life expectancy chart.
(Note: Voltage readings are taken 12 hours after charger automatically shuts off)
