Hi Vernon 777;
Regarding the lithiums, first there is the weight reduction of 2 x 33kg down to 2 x 13kg or 40kg. Usable amps from
2 x 120 x 50% to 2 x 100 x 70%(conservative) or 17% increase. They seem to hold charge better and recharge quicker. Of course they (& the BMS) are expensive but you get the benefits described plus power surety if bailed up for a few cloudy wet days. Longevity over many cycles is also claimed. So far, so good.
Cheers, Chrisso
EDIT: The Lithium battery is 100 USABLE amps so there is a 20% buffer on top. Maths is more like 2 x 120 x 70% or 40% increase.
