    Mobility Scooter upgrade from AGM to LiFePo4 questionsi

    My 24V mobility scooter is a Golden Buzzaround XLS-HD. It's Dynamic R50 controller specs say: Continuous current 14A (driving full throttle on level ground). Max current 40A for less than 60 seconds (accelerating or driving up a steep ramp). I think that means (when accelerating or...

    What is top speed potential of my mobility scooter with reprogramming?

    I improved max acceleration parameter's performance from sluggish to excessive. Now it feels like I was launched from a catapalt. It's now to much acceleration for comfort. Next I'll going to try a max acceleration setting somewhere around medium acceleration. I increased top speed by 0.5 mph...

    What is top speed potential of my mobility scooter with reprogramming?

    Since I already ordered the Dynamic DWIZ-KIT and OEM-U dongle, I think the easiest way to find out if my scooter can go faster is to change the parameters for forward speed and max voltage allowed (if they can be increased). Then I'll drive it and look at my GPS Speedometer.

    What is top speed potential of my mobility scooter with reprogramming?

    I use a GPS Speedometer app on my phone to measure speed. I already increased speed from 5 to 6 mph by increasing tire diameter 1" taller than stock. Although I have not received my Dynamic DWIZ programming kit yet, I did download it's user manual and read it. I also downloaded and read the...

    What is top speed potential of my mobility scooter with reprogramming?

    Hello! My name is Charley. I live in USA and own a mobility scooter that in USA is called a Golden Buzzaround EX. In UK that scooter is called a TGA Zest Plus. It has a Dynamic 90A Type R controller. It has two 12V 35AH (in series) Powersonic PDC lead acid AGM U1 batteries. So a 24V system...
