As you can see I removed all the cells for testing and here they are along with the two replacements.

I am not sure which came first ( chicken or egg) but what I have ended up with is 2 dead cells that are swollen to hell. It makes sense to me that high current would make for high temperature and I assume swelling like I have would surely need high temperature. I think I have read that cells swell w...

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. L...

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 I...

Hi All Just read some of this thread out of interest as I drove to Tims house yesterday to collect some cells for repairing the Astra. Bit of a trip from Norwich so I decided to ICE being as I don't yet have rapid charging 24/7 route from Norwich to the West. I could probably reach the services at P...

Used lead acid cells should not cost much. Last time I took them to the scrap and got 25p per kilo. As you know the export electricity is usually not metered but you get paid for half what you generate. I am not sure if systems are available to use up the excess from your panels by battery charging....

Ah so the regen could be controlled by the brake light switch. Seems a bit crude just to have one level of regen. Is this Zapi normal practice?

Rory

I know you should not reply to your own post but I will anyway. Starting to look at Electrifit Zapi controllers and I see they may do a regenerative braking setup. I think this may be what I have got as there is a complicated array of 5 contactors which seems similar to the photos I have seen. If so...

Yesterday I collected the first Astra conversion from Dragon vehicles circa 2009. Dare I say it, the only Astra conversion? On test driving the vehicle the thing I noticed was the final drive is the noisiest I have ever heard, ICE noise will cover a lot but not this I imagine. The noise is mainly on...

I know this is an old thread but I have just been referred by another forum. The AV2 is not suitable for this adapter as it requires a 12v supply. All that is required I think is a diode and 1.2k ohm resistor to ground to indicate to the charger that car is connected and requesting power. The push b...
