WHAT OUR CUSTOMERS ARE SAYING
We would highly recommend ABC Upfitters. We own a Thor Tranquility 19L and wanted to add more battery (from 400ah to 800ah) and made a trip to Elkhart while we were visiting family in Michigan. Their team accommodated our tight time frame very well and the cost was in line with our expectations. Communication throughout was responsive and professional. Pre and post work walk throughs explained some of the problems we were having and how they would be resolved, as well as the inner workings of our electrical system. Now we have ample battery for our off-grid mountain bike trips.

I rarely get impressed with customer service nowadays, but you guys are the bar that others should measure themselves against. I appreciate you and hopefully, one day, I can return the kindness you have shown.

A big thank you to ABC Upfitters. We traded in our 400ah battery and they installed two 460ah batteries. This will be very beneficial during the summer in Texas. We turned the AC on high, with lights and the fridge running, and we had over 10hrs of battery life!! They even cleaned up some lose connections and made a few other repairs for us as well. They are a great, “down to earth” team and very easy to work with. I highly recommend them if you’re looking to do a battery upgrade

Nerd out with us.
Can you imagine charging your battery bank at 400 amps continuous? We can… and we have.
How about discharging at nearly 500 amps? Yep, did that too.
We snapped these pictures while testing — any guesses what was running on the system at the time?
Wrong answers only.

One of the wife’s “power tools”, I think it’s called “the Jackhammer 3000”..might need even more power than 500A for that though.
My guess is a small fusion reactor. To discharge 500A, possibly a couple rv hookups on the back for your boondocking friends.
Everything?
