Firstly, thankyou for creating such a site BM. The BS and throwaway culture in the mobility sector is exhausting!
I am Michael, 35 from the Highlands of Scotland I have very limited ambulatory powers and strength, a frequent faller thanks to MD but my biggest problem is serious heart failure.
I leave my sofa rarely these days but I do enjoy good weather on a TGA Vita X (that is now seriously failing) I used to enjoy full bore rifle shooting, farming and minor engineering projects.
Currently the Vita has had issues with switching off during use which is incredibly dangerous at 8mph as it is effectively initiating an emergency brake; the batteries (Yucel gels) had had a hell of a run and been heavily mistreated so I couldn't really complain. A pair of 75ah Yellowtop's subsequently went in, along with andersons for 12v charging with a Victron Centaur.
Unfortunately the Optimas came at 12.4 & 12.3 respectively a few good boost charges but the ocv after a run is coming out at >.3v difference between the two batteries; meaning at least one of them has Sulfication and a lower capacity, Tayna are planning to collect them to test but I will get a PL8 on them first.
Out of curiosity (and because it was sat there) I installed a Victron Battery monitor and saw that the voltage under load was dropping significantly <23.3v up a steep hill, It also has amperage, so I did it again and saw it was pulling >120amps compared to 6amps on flat! off a 900w motor with a mass of 220kg including me.
Additionally the scooter is still anchoring up and then refusing to go again for 5mins, I can only assume I have a faulty with the s-drive 200A controller.
Either way it is not nice being 2miles from home and having to get pushed home in freewheel. Programming lead from woody duly ordered and we will hopefully learn what the error is.
