Are there plans to monitor cell voltage and provide cell balancing anywhere in the future?
This gets asked a lot but there are no plans to do this on the Satiator. I'm really firm in the belief that all cell management and balancing etc. belongs inside the battery's BMS circuit, which all lithium batteries should have, and not in the charger or controller. A battery should then present itself as just a + and - power source for a vehicle, and user visible cell monitoring needn't exist, because
a) all the cells are always at the same voltage anyways, and
b) if there is any cell anomaly, then the BMS will terminate further charge/discharge from the pack as required.
I trust the Satiator to not burn down my house when charging - but without a balancing option I'm still stuck with questionable means to monitor, more than balance, weird cells like those from a Leaf/Volt/etc?
If you need to monitor your cell voltages, then the appropriate device for that is cell monitor and/or BMS board, and it has the additional benefit of monitoring not only during charging, but also during discharge, in storage etc. I'm presuming that in these weird cell packs you aren't hooking up a BMS circuit but are running them direct? I know a lot of DIY pack builders are reluctant to add a BMS, since it is a bit of a pain to do, but it's the right thing to do too.

Bingo as well. In the interest of component interchangeability and long term product support, the fewer communications and interfaces between EV components the better.
Currently recovering from the Suntrip race on a back to back tandem solar powered row/cycle trike
. 550 watt solar roof, dual Grin All Axle hub motors, dual Phaserunner controllers, 12 LiGo batteries, and a whole wack of gear.
Now back in Vancouver with my Big Dummy Frame (yes This One
, thanks ES!) with Grin all-axle front hub, Phaserunner controller, and 52V 19Ah Cellman triangle pack
