"What are the SoC voltages for LTO, btw?"
Batteries are SCiB from batteryhookup, rated 20Ah/46Wh per cell, with 2.8V charge, 2.3V nominal, and 1.8V cutoff.
I tested few configurations and choose 7S1P with limited charge at 2.58V max per cell, to use stock Viofo HK4 cable.
Even with limited charge voltage, these batteries provide 100% capacity at low, 1A constant draw (about 12.5W draw at lowest - V cutoff)
So the SoC for the pack is: 18.06V max by charger and 12.6V cut off by HK4 (at above 18.1V, HK4 treats the battery as a 24V system).
(all tests so far are done without BMS, which just arrived from AliExpress)
