Welcome!

There are plenty of people who have talked about trailer range extenders, probably only a few who have done them. Just search for them.

Unless your controller can handle 220V, your only real option to add 96 to your 120V is to make a switch that selects between the packs, so you run one then the other. It would make more sense if you just added 120V so you could run them in parallel and use the same charger for all of 'em and have double the battery power all the time instead of 20% less some of the time.

For just an extra 10-15 miles another option is to run a lithium booster pack like I am.

Thanks so much for the response. I think you are right about the 120 volt range extension pack, make it match....I really don't have to add too much mileage but getting up a few hills is going to nail me. So a full charge heading out , and a little extra to make sure I make it back and the ability to charge a second pack while at work if necessary..... that would be the goal at this point. I have lots of motorcycle parts so making a light trailer without a lot of drag is the idea. It's all new to me but the EV crowd is my kinda folks!
