SiO2 Charging Profile
56.5 constant amps in Bulk is 28% charging rate--expect lower rate to run to a higher SOC before tapering but take longer over all. Here is the old ugly graph again showing 55 amps on a pai...

Ok so at 28% charging rate tapering starts at 80% SOC
at 19% charging rate tapering starts at 87% (as expected-same idea as the ugly graph for FLA)
----------------
There is some info ? that the same happens with LFP but hard to pin down. Needs some ugly graph work! also with LFP there is another aspect where (more rumour ) something similar happens if you use a lower charging voltage. That is different from the ugly graph where the same charging voltage is used but different amps per size of bank in AH.

I found my test result on the one SiO2 back in Oct 2020 where I used the Vector at its 20 amp setting (it did constant amps at 19 amps for a 19% charging rate)
" using the same Vector charger as in my ugly graph with flooded 27DC type batteries, and a 19% charging rate, the Vector stayed in constant amps until 76% SOC Flooded and 87.5% SOC with this SiO2 batt. Amps then taper.
Not attempting to compare tapering times since with the Flooded it is very flat 90-100 but steeper for that last 10% with the SiO2. Certainly you get a "faster recharge" from 76% SOC on up because one is tapering and the other is still in Bulk constant amps for part of that range.
At the 19% charging rate used for this test, it is the same times up till 76% -can't be faster, the charger can't do faster, but eg, with the Flooded, the 80-90 part takes an hour of tapering, while the SiO2 takes about 1/2 that time then tapers."
