The fact that LiFePo4’s charge faster than Lead Acid can been substantiated per numerous industry papers (readily googled, ad nauseam...), and many credible personal accounts (RV.net)...Along with a near lack of voltage sag, long life and no maintenance, it’s this rapid charge characteristic that makes Lithium (and variants) the practical ‘elemental chemistry’ of choice for solar charged UPS power walls and regenerative braking in autos, and a worthy attribute at higher latitudes where peak harvest periods are often greatly limited...
