Lead acid will not last decades in Phoenix based on my experience. Shorai had a sale last year so I picked one up but it does NOT have an internal circuit for charging. Picked up a L-Ion battery for my go box battery supply (telescope, ham radio etc.) and it DOES have the extra circuitry. Got it from Batteries Plus and Bulbs. No more Shorai for me.
