I have a Yeti Goal Zero Lithium 1000ah battery with usb, 12v and 120v outlets. I could put it in a trailer to recharge my battery via the standard charger, but it’s heavy and moderately bulky and I’m not sure just how much it would extend actual ebike battery life. I run a BBS02 fat tire bike and use a dual battery parallel wire to run a 48v 10.4 ah and a 48v 20ah battery.

Yeah, but how much would hauling that thing around on a trailer suck the fun out of your bike ride? The specs say that it weighs 40lbs. A second 10-15lb battery would double your range and you could carry it in a pannier. I guess if you already have the trailer, you could try it.
