lithium question
Can you charge lithium batteries with a regular charger or do I need to buy a special charger?

BFL13,
Given that SiO2 can do 4C continuously, and can be taken to 0% state of charge, why would you suggest that it takes 2 SiO2 to equal 1 LiFePo4?
because while they can go to 0 state of charge a lot more than a normal floded battery it is not a free reign to do it as it still damages the SIO2 and they can only do it so many times. the manufacturs still recomend staying in the top 50% state of charge to get the advertised cycles. I look at SIO2 as a normal battery that can take abuse if you neglect it now as one to try use like a LFP battery for cold wether. they still have lower cycles , cold weather capacity drop off and all the other issues asocialted with flooded batteries but they have a better ability to handle ocasional deep discharge to 0 and have a higher discharge capacity, but for some reason a lower charging capacity...
but I think it might take two LFP batteries to replace the discharge of the SIO2, not because the LFP cells cant handle it but because the adverage BMS is set at a 1C discharge and I dont think that will be enough for a microwave. the bonus side is with two LFP you will get 180 AH of usable power aposed to the 50-60AH from one SIO2 and you can discharge a lot more before your inverter will start giving the low voltage alarm.
