Dead Battery GT
Sorry if this is posted the wrong thread, but 1600 miles in and my battery is dead. It will cost me about £565 to replace the battery but I'd much rather have a VESC board at this point.
What are my options for VESCing a GT with a dead battery? I know tyre options are limited somewhat due to the 6.5" hub, but is there anything worth considering if going down this road?
@reelwons Either way, you will have to get a battery, a stock or aftermarket battery and 18s battery is good for vesc later on if you decide to go that route.
However, if you have updated your Gt to the latest firmware with haptic buzz then you cannot replace the battery and pair the bms by yourself without an intrusive procedure.
Vesc conversion is not recommended for a beginner without soldering experience.
@reelwons Just figured it might be worth asking. What about the battery is dead?
Is it just not getting the same range it once used too, refusing to charge or something else entirely.
@lia I believe one or more cells are dead. I left on 75% charge and 20 minutes into riding the battery died while I was doing 18/19mph. I bailed, checked the app and it showed 1%.
Prior to this happening it was balance charging for about 4 days.
Similar thing happened about a month ago also.
@reelwons Ouch that does sound like a bad pack. Lemur's suggestion is probably the best one as the replacement pack will still be good for a VESC build if you go down that route later.
It may be possible for it to be restored with replacement cells but you would need someone capable of dismantling the welds and then welding in new cells. Afterwards the board would recalibrating as disconnecting the battery from the BMS causes an error that disable the board till cleared.
Just to re-iterate Lemur's point this only works on firmware versions prior to haptic buzz.
