I want to charge up my batteries in the field. The battery I’m looking at is a YUASA 12v 95amph battery. Just wondering how many charges of a 6S 4500 @30% charge to full from this battery I could get

Hello Simon Bee
Most RV batteries will provide about 50-60% of its labeled Ah rating before the voltage falls below what most 6S LiPo balance chargers require before hitting low voltage suspend charge mode.
For ballpark calculations, the 6S 4500 @ 30% is gonna require about 3500mAh of juice to attain a full charge.
Derate the YUASA down (50-60%) from 95 to 52 (median of the derate %) and divide by 3.5 (3500mAh) = approx 15 charges
A good 15amp 12v charger will also be an important piece of equipment for keeping the Yuasa in good condition.
