Absolutely, I had battery tender that quit, now I have a genius smart charger. Seems to work fine. I also do quite a lot of boondocking so I installed a 70 watt solar panel and a 30 amp solar charge controller just to keep the chassis batteries topped up. This is on an Allegro Bus. It came with a battery tender installed from factory.
