stir find me an LifePo4 that works reliably at -40 with no "self heating". The only one I know of is Lithium titinate which is way beyond my budget. (at the time $1800 for a single 100 amp-hour)
I'm glad your choice works well for you.
SiO2 are a much better fit for me except for cost.
which is exactly why I am surprised your even comenting on this thread, you have dmisitidly stated you will never have LFP as you won't make alowances to make them work by putting them in the conditiond space or other simple things, so why are you interested in a thread on how to build one, I am actualy curious.
actualy LTO has come down a lot in price you can get 45AH cells for 39 bucks each and it takes 6 to make a 12V battery. so you could do a 90AH battery for about 684.00 plus what ever your BMS for that costs.
