Sure Power update
Time for an update.
Yesterday I received my replacement sure power. They actually sent me the 1315-200 instead of the 1314-200. All that means is that this unit will connect both batteries as long as the main or aux see a voltage over 13.2V. For example, the unit will connect with the engine running (alternator is providing the charge) or if I connect a battery charger to the spare battery. The 1314-200 will only connect if the main battery sees a voltage over 13.2V. They call it bi directional (1315-XXX) unit as opposed to a uni-directional (1314-XXX) unit. Hope this makes sense.
Anyhow, I've installed the replacement unit and it works fine. I'm going to wait for a few weeks and report on how it's holding up.
Cheers :beer:,
