Expert Answers about Battery Charger


  • Portable Solar Panel Charger for Charging RV Batteries During Day
  • That amount of amperage/wattage that the two charger kits you mentioned are capable of really wouldn't be adequate to charge a depleted battery. Especially in a day as they are more designed to keep a battery topped off in storage more than anything. These both can put out up to 7.5 watts. You'd want something with more output than that like the Goal Zero Boulder Briefcase Kit part # 287-32408 which is rated for 100 watts.

  • How to Keep Deep Cycle Battery Charged for Winch and Trailer Light Usage
  • The positive terminal on your deep cycle battery will connect to the 12V circuit from your 2018 Ram 2500 to provide a maintenance charge and you do ground the battery from the negative terminal to your trailer frame. With that being said, the 12V power from the alternator on your Ram will provide a trickle charge at best (which keeps the battery topped off when not in use) and it won't actually charge the deep cycle battery completely. Since it sounds like you are looking to use...

  • How To Attach the Redarc In-Vehicle BCDC Battery Charger To the Start Battery
  • The Redarc In-Vehicle BCDC Battery Charger part # 331-BCDC1250D needs to be installed on the trailer, next to the service/auxiliary batteries. That said, this now means you must run a wire from the Redarc In-Vehicle BCDC Battery Charger to the start battery in your vehicle. The correct size wire to use will vary based on total length as you mentioned. I recommend you go pretty large so you don't have to worry about issues with length or voltage drop. We actually have a kit that will work...

  • How to Install 7-Way on 2020 Hyundai Palisade for Brake Controller
  • The best option we have right now (August 2019) is for you to install the 4-way on your 2020 Hyundai Palisade from Hyundai as we don't have an option yet, and then convert it to a 7-way with the part # ETBC7 which comes with everything needed to install a brake controller and convert the 4-way to a 7-way. For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup....

  • Can BRW77FR Be Wired To The Battery In Conjunction With A Solar Charger
  • The problem to watch out for, is not the voltage, it's the current (cfm). If your battery recommends 30a max charge current and both of your chargers are rated at 15a, you're good to use them both at the same time. If your chargers are both 30a units, then you could damage your battery. Since both the Solar # BRW54FR and wall charger # BRW77FR are 7.5 Watts I don't see there being an issue. The wall charger has a cut off when the batter is fully charged and the solar will maintain the the...

  • Recommended Way to Charge my Trailer's Breakaway Battery
  • Both the CTEK US 0.8 Universal Battery Charger with Pulse Maintenance part # CTEK56865 and the Bright Way Solar Battery Charger and Maintainer part # BRW54FR would work well for this application. I prefer the solar option as it wouldn't require shore power.

  • Can Redarc In-Vehicle BCDC Battery Charger be Used to Jump Start Battery
  • In addition to the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D you need to use a Redarc Smart Start Battery Isolator. I recommend using the Battery Isolator with Wiring Kit # 331-SBI12KIT if you don't already have the fuse kit, or part # 331-SBI12D if you do already have the fuse kit. With the isolator installed you can then connect a push-button into your system to help jump your start battery.

  • Charging Lithium Trailer Batteries While Driving
  • Yes, your solution is a DC to DC charger as there is not a "good" way to charge your 100Ahr trailer battery using your Tacoma's 7 pin connection only. You will get some low amperage trickle-charge while hooked up and the alternator running, but not enough to fully charge your trailer battery. For systems where your trailer batteries are rated for 75-200 Amp-hours, use the Redarc # 331-BCDC1225D 25-Amp, Dual-Input DC-DC Charger. You will additionally need three Redarc # 331-FK40, 40-Amp...

  • Adding a Second Trailer Battery to Power Trailer Accessory Lights
  • While you can add a second battery to power lights, this is going to require a second, 12 volt auxiliary battery; this is the same concept you were thinking of but a breakaway system battery isn't going to have the power or amp hours needed for your lights. Doing this is fairly simple as you will just need to start by mounting Battery Box # 329-HM318BKS to your trailer frame with some self-tapping screws and washers, like you can see in the linked video review of this box.

  • How To Choose the Correct Redarc In-Vehicle BCDC Battery Charger for Auxiliary Battery On Vehicle
  • In order to choose the correct Redarc In-Vehicle BCDC Battery Charger you'll need to know the amp hour capacity of the battery bank. This would not include the starter battery for the vehicle just the auxiliary battery, the starter battery would get more than enough charge from the vehicle's alternator. Therefore, for a single 12 volt battery you'd need part # 331-BCDC1225D which is rated for 75-200 amp hour batteries (Odyssey PC2150 = 100 Ah). The Redarc In-Vehicle BCDC Battery Charger...

  • What Ignition Circuit Does 60-Amp Relay Kit for Redarc # 331-BCDC1225D Wire To
  • The pin of the relay that comes with the # 331-RK1260 that runs to "ignition" only needs a power source that is active when the key is on to basically tell the relay to activate. You don't have to actually splice into ignition wiring. So basically any circuit on the vehicle that is only active when they key is on would work when installing the # 331-BCDC1225D.

  • Choosing Between The Redarc 25 amp or 40 amp Model For A 2018 RAM Promaster 1500
  • Your 180A alternator will work fine with any of their BCDC models. Whether you need a 25, 40 or 50A model will depend on the size of the battery bank you’re planning to charge. If its between 75-200Ah the # 331-BCDC1225D model will be fine but if its greater than 200Ah either the # 331-BCDC1240D or # 331-BCDC1250D will work best to replenish the battery bank faster. Yes, the BCDC can accept unlimited solar Watts/ Amps but its output is limited by the model chosen (i.e. 25, 40 or 50A). Yes,...

  • How to Pick Out Redarc DC to DC Battery Charger for 450 Amp Hour Battery Bank
  • The only difference between the Redarc # 331-BCDC1240D and # 331-BCDC1250D is the maximum output rating of 40 amps and 50 amps, respectively. Both of these charging units are designed for battery banks above 200 amp-hours. The difference in output means that the 50 amp version will charge your battery from dead to 100% charge faster than the 40 amp version. Overall, I recommend the 50 amp version as it would be able to charge a dead battery faster than the 40 amp version.

  • Will the Redarc Smart Start Battery Isolator Work with Three 100 Amp BAtteries in the Battery Bank
  • The Redarc Smart Start Battery Isolator part # 331-SBI212 will work great for your application as long as you have your 3 100 Amp deep cycle batteries wired in parallel and it is 12 volts. If your batteries are wired in series and output 36 volts it is not compatible. The size of the battery bank does not effect the isolator because it is past the isolator in the path. The 200 Amp rating means that it is rated for 200 amps passing through it from the vehicle into the battery bank.
