SiO2 Batteries and High Amp Draws
SiO2 is a specialty battery type that most folks would have no use for vs the usual RV battery types. They cost a lot too.( I had a special reason to get one) Here is some info on them --I am not s...

Small resistance numbers may make dramatic differences.
It is an advantage to have fewer battery management systems.
For example. One battery at 20% state of charge, and another at 80%. (Yes, I know that is not usual). The BMS in the 80% will shut down first, leaving the other battery only partly charged.
no it wont shut down both batteries, the BMS in one battery doesnt magicly shut down the other ones and it definatly isnt going to shut down a battery at 80% the BMS is not a controler as you see it, it is a monitor with a out of range protection. so it doesnt control charging (well if you have an active balancing feature built in it will control that only) but as far as charging goes each batteries BMS will only monitor that battery. as charging happens if one hits a charg limit it will shut down that battery and the other will keep charging, but if you hit that limit before the other are charged that is another issue all togeather,as in you shouldnt be allowed to wire batteries togeather no mater what type they are.
you theory about little resistance differences applied to every battery type, and thats why when we conect batterys we use larger than required cables and arange them in methods that give you the same lenghts of cables so resistance from cables and the conections are the same. well most of us do, I have seen some pretty ugle battery jobs...
you spout off numbers that are for different chemistries, you make issues that apply to every battery type sound like there unique to Li. it almost makes it seam like the SiO2 dealer is paying you , but we know that isnt true or you would actualy have that kinda battery.
