FYI:Below is a chat from a week and a half ago with Amped outdoors I had pertaining to charging in cold temps.
I have a couple of 36v 60AH batteries from last year. I am headed to Green Bay today. it looks to be below freezing at night. chances are I can go 4 days without having to charge the batteries, but if on Monday night when I get done fishing. I would think it will be in the high 30’s. if I start to charge them above freezing do I need to watch the Temps as it charges and if it drops to 32f unplug the battery charger then?

If using our onboard charger, the batteries will charge as low as 17 degrees. You don’t want to make a habit of it, but in a pinch if you need to charge that low you can. If you don’t want to drop below 32 degrees and the batteries get an adequate charge you certainly can stop the charger early. Thanks.
