• Recommended Vehicle To Trailer DC to DC Charger for Multiple Trailer Batteries
  Your auxiliary power wire gauge at your 7-way along with the discontinued CTEK40186 will be sufficient to charge your trailer batteries. The CTEK D250S will amplify the signal from your auxiliary power to boost it to 20 amps versus the 2-3 amps of a system without the CTEK unit. Changing your gauge of wire to 8 and adding the # DL24086 connections will help slightly but if you are wanting to charge multiple batteries well and more quickly/efficiently, you really will want the discontinued...

• How to Tell if Tow Vehicle Has Smart Alternator to Install Redarc BCDC Charger
  I have a way for you to test and see if your 2007 Nissan Xterra has a smart alternator (I doubt it does), but I unfortunately don't have a list of what vehicles have a smart alternator so it will require you to do some testing: 1. Locate your main vehicle battery 2. Start the engine, ensuring any fans, radio, lights etc. are turned off. 3. Take a voltage reading across the main vehicle battery 4. Leave running for around 5/10 minutes, then repeat step 3 If your readings are around 14.4V...

• Is Relay Kit Needed for BCDC Installation if Ignition is Already Ran to BCDC on Trailer
  If you have an ignition wire running from your 40 Amp BCDC # 331-BCDC1240D then the 60-Amp Relay Kit # 331-RK1260 isn't needed. There just has to be enough power on that wire to reach back to the BCDC so it can read the alternator properly. Basically if the BCDC is reading everything properly then you have enough power. Otherwise you need the relay kit. If you were having a problem running the ignition wire all the way to the BCDC then that's when the relay kit would be used.

• Why Do I Need to Use the 60-Amp Relay Kit for a Redarc BCDC Battery Charger
  The reason why Redarc recommends using the 60-Amp Relay Kit # 331-RK1260 and larger Anderson connectors like the kit # BDW20047 when installing the BCDC Battery Charger # 331-BCDC1240D is due to the smaller OEM gauge wire that is used on your 2019 Ford F-150 (and other pickups) for that 12V power. If you think of electricity like water and the wiring like a hose, you want the biggest hose possible at the source (your battery) so you have the most amount of energy getting to the BCDC as...
