Jumping a van requires a match connexion.
There are two ways to wire in dual batteries on a motorhome or camper. One form is to wire the batteries in equal, which does not spending money the voltage of the joined batteries. Two parallel-wired 12-volt batteries Testament favor exceeding capability, on the contrary the voltage remains 12 volts, unlike two 6-volt batteries wired in a series. In a serial connexion, the two 6-volt batteries revenue 12 volts. Output voltage in a serial connexion is the sum of all voltage of the batteries within the connexion. A popular tube flashlight stacks two 1.5-volt batteries to aglow a 3-volt blaze bulb.
1. Spot two 12-volt batteries adjacent to Everyone other that Testament fit in the battery box existence of the camper or motorhome.
2.3. Bolt the fine cable eye of the unconnected battery to the cold terminal of the battery that's connected to the camper. Bolt the counteractive cable eye of the unconnected battery to the balky terminal of the battery that's connected to the camper.
Serial Battery Connection
Connect the fine and balky terminals of one battery to the useful and abrogating cables of the camper. Connect two cables --- one to the decided terminal and one to the negative terminal of the unconnected battery. Both these cables should bear eye connectors on the other aim.
4. Spot two 6-volt batteries side-by-side that Testament fit in the battery sphere of the camper. Two 6-volt batteries in series will yield a 12-volt output.
5. Connect the positive terminal of one battery to the negative terminal of the other battery. Use a battery cable with one positive and one negative terminal to make the connection.
6. Connect the two open posts of the two batteries in the serial connection to the camper. Connect the open positive post of one battery to the positive cable of the camper and the open negative post on the other battery to the negative cable of the camper. The serial connection will yield 12 volts at the camper connection.
