![]() This combo is what I would buy were I going to do it again. A dual sense relay will allow solar or any other charge system connected to the house battery to charge the starting battery once the house battery is fully charged.Ĭan buy an ACR/VSR in combination with a marine battery switch so that you can force the two batteries to be paralleled or even switch the starting chores to the house battery if need be. to charge the 'house' battery last it will never turn on when the solar panel has charged the 'house' battery. With a single sense relay set up to allow the alt. Single sense relays only sense the voltage from one side. Dorman Conduct-Tite Battery Isolator Switch - 85988 Part : 85988 Line: CTI 3.8 (12) Select a store to see pricing & availability or search by City & State or Zip: Find 1 Year Limited Warranty Color: Black Material: Plastic Terminal Type: Screw Compare Cole Hersee Battery Disconnect Switch - 08099080BP Part : 08099080BP Line: CH 4. There are two versions of the ACR/VSR's, single sensing and dual sensing. Relays also disconnect when the charge voltage drops, be that because you turned the engine off or there was some large draw on the starting battery. to charge both at the same time, even when they are not at the same state of charge. to first bring the starting battery back up to full charge before connecting the 'house' battery to charge it. The Automatic Charge Relays and Voltage Sensing Relays (different names for essentially the same product) don't have any voltage drop and do something that the diodes can't. I prefer to use a robust marine battery switch for those needs. I don't buy the marketing for those semi-automatic relays that have a remote switch. The constant duty solenoids pre-date the diode isolators and are still a better option though the automatic relays are better still. There are constant duty solenoids (BIG relays) and there are automatic relays. Unless the alternator's voltage regulator monitors the voltage, ideally, at the battery, or not quite as ideally, downstream of the diode isolator the batteries will never see a full charge. so it kind of depends on what you want, if you want it just like a camper, and don't want to worry about switching or forgetting then Diode would be best for you.ĭiodes have a small voltage drop. I did this when I turned off the truck and built the suspension for a couple weeks, before realizing I left it on the WVO tank and just that little bit wasted the battery.īut always, the Simple turn switch under the hood is the simplest and least (basically no extra) wiring.Įdit: As well with a Diode you can't use the batt except for auxiliary stuff, won't help winch, start the truck ect. ![]() ![]() Does that make since? so always closed will more then likely be "off" on your cab switch so if you leave your cruiser for a week or two you don't drain your batt. Just make sure you wire the relay the way that is least likely to wear your batt down wile the switch is on. Either a big manual switch/ isolator (you can get like 400amp ones and HB for cheap) Or the relay route so you can control it in the cab. I am about to do my double battery on mine and I am going to do it the way it did it one my other vehicles.
