Charging 360V pack

They are going to have some charging challenges with those higher voltages.
Check here EVTV Motor Verks Store:

And scroll down to Configurable 4kW Charger

TCChargerModel: 208v 22A
258v 18A
290v 16A
389v 12A
Price: $1,895.00

So the TC Charger will go to 389 (may be a bit high? maybe not) at 12A or so.

I hope it works OK - I ordered one.

Charging shouldnt be an issue in the US. I had my local power company tell me they can get me what I wanted up to 440 volts with its own line and meter.

I was thinking of the individual cell voltages But line voltage is a consideration at some point too.

If its really cheap to have the right line voltage brought into your house (cheaper than a proper charger) you can eliminate a lot of components and dumb charge with an Ahr counter/cutoff and voltage cutoff.

A few folks do that using cap chargers, by the math they are only about 5% less efficient than a real charger.

Yah, string charging is a lot simpler, dig up a suitable transformer if you have too. I was thinking of balance charging with an "odd" voltage per cell. Unless someone can reverse engineer the can protocol on it and/or the hardware on those packs...

Not-as-good battery prices

The older CALB SE series, 100 A-h cells are on sale at EVTV for $1.00 per amp-hour. Elsewhere they are still over $1.30 per amp-hour.

About $312.50 per kw-h. A 24.3 kw-h pack would be 76 cells ... or $7600 ... not $3600 .. including the battery straps and washers.

Nominal pack voltage would be 250V in series, or 125V for 2 parallel strings.

For comparison, the CALB CA 100's are $150 at EVTV, $135 at EVWest.

They don't have the performance (higher battery sag under load, lower maximum current) that the CA series do, but I think they are .. sorta .. comparable to the Renault pack
