I don't get how this would work..? how are you going to get up to full pack voltage for charging? Inverter?

That's how I do it on a smaller scale for my recumbent. I step 12V up to 58V open. Yeah there are some losses, but it's still worth it.Animalector said:I don't get how this would work..? how are you going to get up to full pack voltage for charging? Inverter?

As long as you're using a charge controller to limit the amps being fed between the two packs, I wouldn't see a problem with it. It would be the worst idea ever if you didn't use a charge controller though, because the only thing that would dictate the charge rate would be the voltage differential and the resistance between the two packs. It would surely exceed the continuous charge rate if you had a dead pack on one side and a full on the other.

We don't get many Tesla wrecks down in Australia yet the odd one or too but we have our names down, I could turn my Winston pack into a fast charger do you know if one more cell would be enough?
Thanks Kiwi
I'm not sure what you mean by "one more cell" being enough. For a fast charger? Of what?
By the way, the rear cover looks great. It's nice to be able to tell if mods like that make a difference just by monitoring cruising power consumption.
Cowardlyduck said:Awesome stuff mate. I found similar result after putting the wind deflecting solar panel on the front of my recumbent. Aero makes a huge difference to EVs.
As for the charge controller/converter for a 162V battery...I see what you mean....I can't find anything with decent power that will do that high a voltage.
That really sucks as that's the only thing preventing you from being able to do it really.
The other horribly inefficient option is to use a regular MPPT to 240V AC, then run a regular charger off that. Maybe with a small 12V battery before the MPPT it would even out any power dips.
At least it would work

I bought some 57ah kokam cells plan to make 96v pack for8kw e motorcycleKokam have a reputation for producing high quality, high performance cells.
At 5/10C discharge, those are not the most powerful cells they make, but it depends on what you need from your pack.
Are they new , ? Or "salvaged" ?
At $0.5 /Whr they are priced similar to the 20Ahr A123 pouches.
