Expert Reply:

For your larger battery, I do recommend the CTEK MULTI US 3300 12-Volt Universal Battery Charger, part # CTEK56158. This charger is designed for larger batteries like the one on your trailer.

The 12-volt accessory circuit on your 7-way trailer connector can be used to maintain a charged battery, but it won't have enough push to charge a discharged battery.
