last night went to our local Tuesnight pub crawl ... R80G/S had been sitting for a week.
Shorai LFX 36 resting at 13.42v or 100% full. G/S started right up with quick crank. temp was about 50f in garage.
short 10 minute ride to Crawpappys with heated suit and heated gloves on. G/S parked outside for about 3.5 hours while meeting (food&beer) with our local Adv group.
about 35f outside a light layer of frost ... turned on lights a few minutes allowing LFX 36 to warm up a bit. engaged choke, then cranked and cranked and cranked. for some reason G/S decided not to cooperate. LFX 36 was getting a serious workout!
finally after cranking for over 3-4 minutes (not continuous) then turning off choke... R80G/S sputtered to life. then plugged in heated jacket/gloves for the short 10minte ride home.
next morning took a reading ... 13.32v or 90% full... not bad considering all the cranking night before, then heated suit/short ride combo with no chance of alternator having enough time to recharge fully.
