The Bright Way Deep Cycle RV or Marine Battery # BRW94FR will provide you with a 100-amp hour battery and is a deep-cycle AGM battery that provides long-lasting, dependable power for your trailer.

The charge that you get from your 7-way will only be enough to trickle charge your battery. Essentially it will maintain the battery if the battery is not being used for other things, it will not charge a depleted battery. In order to actually charge the battery you will need to use the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D which will use the vehicle's alternator to charge the trailer battery while the vehicle is running.
