FWC yes, with SiO2 you have to deal with an absorb phase, once every 30 days. I'm sorry you see that as such a hardship.
For those of you who really want Li at an extremely competitive price surf here:
https://ablithium.com/$400 for 100 amp-hours, drop in with BMS. Plus shipping.
My own opinion is that SiO2 have never caught on due to their high price. Some how Li has circumvented that.
As to Li such as battlebord, they are really a 120 amp-hour battery with a BMS that cuts off the bottom 20 amp-hours. I wonder how that will work out as the batteries age.
