Have been running a lithium Batt for about 2 years now. Love it and never a problem. Light, small plenty of power. Rode to both the 18 and 17 Nationals without a problem. Last week at the SW E&M&G&R in Death Valley temps at night dropped down to the mid 30's. Don't think in the past the scoot has been exposed to overnight temps like that before with this setup. I know the lead batt didn't like cold. 14 hunney was slow to crank and start. She started but struggled. Going to check connections but pretty confident they are clean and good. After that clean cranks like normal. I've heard lithium batt's don't like the cold. Do I need the counterweight to knit a battery sock? Or after 2 years is the batt getting weak on CCA?
