Re: Dragon Astra TLC required

Mike Yes 1st gear is probably not needed. I think the final drive has failed rather than the input because one side is much noisier than the other. There is a top balancing BMS in the charger but nothing to monitor individual cells at the bottom. I will leave things as they are for the time being. ...

Re: Dragon Astra TLC required

Thanks to Tim I now have some cells to repair the Car. When I got home from Tim's house there was a replacement gearbox sat on a pallet so I had better get cracking. I suppose the huge torque that an electric motor can produce in first gear must have destroyed the final drive bearings. Before that ...

Re: Elecscoot E4 scooter with LiFePO4 cells

Hi All, I purchased the scooter from Colin and thought I'd continue this thread with its repair. It had 15 miles since new (2012). Diagnosis The reason for this appears to be a faulty battery pack. We found that the pack was not wired correctly in series and there was one connection where the positi...

Re: Elecscoot E4 scooter with LiFePO4 cells

*confused* ... I'm near Birmingham, ... given ... your remote location ... Birmingham is the least remote city in England. Maybe a good deal after all? Ah.... I must have got confused with another thread.... I had Elgin in my head for some reason! Colin, I'll happily take it if the price is right. ...

Re: Elecscoot E4 scooter with LiFePO4 cells

Hi Colin,

My company might be interested in taking it off your hands but given the battery is likely duff and your remote location we likely can't offer much.

Send an email to mike at indra.co.uk and we can discuss.

Cheers,

Mike

Re: Alittle advice with charging final phase with lifepo4

Hi, I have got a 76 cell lifepo4 pack that i have been quietly tinkering with for optimal set up. I have modified the zivan charger with help from Dave at electrofit zapi which required a 20k turnpot to be fitted in place of a 2k on the voltage set point which gave more voltage adjustment, plus the...

Re: Is a BMS actually necessary on LifePo4 cells.

Grumpy, good explanation. I agree with everything you say apart from the cut off voltages but that's down to your own risk appetite :) Thought I would add a bit more on the topic of battery monitoring systems. Typically, this will be a method of sensing voltage attached to each cell. Usually a cable...
