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. Could you tell me more details of the new battery? make and model etc? Even got some good specs? That would be useful for me.
