Tow Vehicle Battery and Alternator
My trucks alternator is rated at 150 amps. Its starting battery is your typical 600 CCA AC Delco variety. My goal is to increase charging capability through the 7 pin pigtail connector near the hi...

I would stick with the existing charge wire and just get the DC/DC booster mounted on the trailer. You will need to be 10 amps rated lower than the charge line. Most of these lines are fused at 40 amps so you are looking for the Renogy 20 amp DC/DC charger. The manual says you can use the 40 amp rated on a 40 amp fuse but I don't buy that.
Three hours at 20 amps is actually a good charge into the battery. The existing alternator will do just fine. Yes it does the three stage charging routine putting full voltage right on the battery terminals and will be a huge improvement. Use the setting for 14.7 volts on the pair of GC2.
Charge to 90% is fairly quick at this voltage and the last 10% takes some extra time no matter how many alternator amps, charging capacity or wire size.
