I like lead acid since it's hard to blow them up and burn the house down. Lithium on the other hand... But if I buy another battery it might be Lithium. Put it in a steel box, 10 meters from the house. Maybe OK. Yes, whatever you are happy with. The Lithium type (LYP) I originally bought does supposedly not burn, it has not in the 8 years since I got them but I had two internally shorted cells - and no fire at all - by now. The new bank is the Lion type EV power sells, so far no problems either. Batteries are inside my games room/workshop and not yet in a box (future project). Nice thing about lithium, saw 90+Amps charge current going into the 2 x 200Ah bank today and they can take all I can throw at them. Fully charged around 55V  and I have never seen them below  53V. My house is completely off grid now.
