I own Sportmen classic 180 QB 2017.
Question 1.... can I run a battery charger connected to a generator, while the trailer battery is still connected to the trailer and the trailer is connected to shore power?
Question 2.....can I remove the battery from the trailer (to conect it to a battery charger) and still have the shore power co acted to the trailer?
I am told that while boondocking, to charge the battery running a generator conected to the 30 amp plug, will take a long time, however if I use a portable battery charger (good quality), the battery will be charged much quicker. It was suggested that I conect tbe generator to the trailer via the 30amp plug and use the 120V outlet on the generator, to run the battery charger and charge the battery.
Not sure though if I must remove tbe battery or leave it in place and just add the battery charger clips to it?

I own Sportmen classic 180 QB 2017. Question 1.... can I run a battery charger connected to a generator, while the trailer battery is still connected to the trailer and the trailer is connected to shore power? I have a 2011 Sportsmen 19bh so I am sure yours would be the same. It should have an inverter on it that will charge the battery on the trailer automatically while you are hooked up to shore power. So, I you should not need to run a battery charger off of a generator to charge the battery. In this situation you would not want to hook up a battery charger to the battery while on shore power. Question 2.....can I remove the battery from the trailer (to conect it to a battery charger) and still have the shore power co acted to the trailer? Yes, if you remove the battery from the trailer, your trailer should still run fine on shore power since it has the inverter for 12v stuff as well as the 120V directly from the shore power. You could then charge the battery without it being connected to the trailer. But, again, there is no need as the battery should be getting charged anytime it is hooked up to the trailer and the trailer is plugged into shore power. You can also charge the battery with a battery charger when the trailer is NOT hooked up to shore power.I am told that while boondocking, to charge the battery running a generator conected to the 30 amp plug, will take a long time, however if I use a portable battery charger (good quality), the battery will be charged much quicker. It was suggested that I conect tbe generator to the trailer via the 30amp plug and use the 120V outlet on the generator, to run the battery charger and charge the battery. Not sure though if I must remove tbe battery or leave it in place and just add the battery charger clips to it? The battery will probably charge faster with a 10am - 12amp battery charger than it would be charged by the trailer charging system. You do not want to charge the batter any faster than about 10-12amp as it will decrease the battery life if you try to charge it faster than that. |

Question 1 Yes Question 2 Yes Usually the onboard charger will not go into the high charge rate because the wires are too small and the distance too great. You can try fixing that with MUCH larger wiring. The converters installed in these trailers are not the best, so upgrading is also a good idea. You can call Randy at Bestconverters for advice and parts. Otherwise the battery charger will work just fine except for the noise and inconvenience. |

Thanks guys, appreciate the info. I will most likely disconnect the battery from the trailer and connect it to the battery charger, which will be conected to the generator (120v plug).
I will at the same time connect the 30 amp plug on the generator to the trailer.
This should allow the trailer to have power and let me do a charge of the battery quicker than if I just left it connected to the trailer and let the trailers charger do the job
