SiO2 Batteries and High Amp Draws

StirCrazy, you are right about the cost etc. And LFPs do better for high draws.

I got sort of sucked in--sad tale of woe follows:

I got one for the camper when the scenario was to be 1 day trips to local dog things so DW has her own hideaway and bathroom. (Class C too big for that job) and I wanted the MW to work for her off the inverter.

At the time the 100AH SiO2 was $700 and a 100AH drop-in LFP was $1400. (They still are around here!)

Then DW said the new plan was to use the camper for weekend dog things so 100AH was not enough. Goal posts moved. Oh well.

So I decided I was stuck with having to get more battery and it had to be the same type (perhaps wrong on that, don't know). So got a second SiO2 for $500 this time on sale. (They must have wanted to unload some inventory before Xmas maybe) So now that is 200AH for $1200 vs 100AH for $1400.(200AH for $2800 yipes!) I also stole a solar panel off the Class C for the camper.

But now with 200AH bank the 55 amp draw of the MW could have been done by ordinary AGMs. 200AH AGMs about $500 then (700 now) Drat.

Water under the bridge and I do get to use the kettle at 90 amps as reported. That other guy on here wanted to start an SiO2 club, but there was no T-shirt so I didn't join. Maybe it was really a "support group" :)

haha, weird that they are so expensive there for LFP. you had to order the Sio2 and just doing a quick search a drop in bought online from alberta lithium is 550ish this one

but ya it makes sence if you alreay had one to get another , after all what are you going to do, throw it out.
