The OEM pack is ~230V, and the aux pack is 48V. They use a 3000W dc to dc converter to slowly charge the OEM pack from the aux pack. There is also the issue of capacity. The OEM pack is just under 1kWh (which you can't nearly use 100% of) and the aux pack is 4kWh. I agree it would be better to parallel them, but thats just not how this kit is setup.
