I’m a wet cell lead acid man myself.
There’s the monthly battery fluid level check to contend with but if you can make sure it doesn’t tip over too often or too long and you can bank on being able to get to civilization once every six or ten years then you’re in the low total cost of ownership ecosystem.
Of course, they’re not as good in the cold and if you screw up and let all the water leak out then you gotta fill it back up and hope it’s not too messed up.
Whatever you pick will be fine. Tbh if you’re not gonna have the trailer for longer than the life of the battery, pick the one that’s got more curb appeal or resale value!
I meant the ~300 mile ranges common in electric cars. That’s a long trip. Plus if the car rolls to a stop by the side of the road you just gotta have it towed or charge it up in the field somehow, electric bikes have pedals.
It sucks to pedal a heavy ass ebike but you can do it in a pinch to get where you need to go.
