Do you need a battery isolator?
Regardless of how many batteries are available, the current flow from one battery to another will continue until all batteries in the electrical system reach the same charge level and may prevent the engine from starting. A battery isolator can eliminate the problem of battery drain all together.
Do dual batteries have to be the same?
Yes, you’ll need two batteries for the best dual-battery setup, and you’ll need two different kinds of batteries. The primary unit should remain a typical starter battery.
Can you charge a second battery with jumper cables?
With another Car Battery. The second method for charging a car battery is to use jumper cables to connect the dead batter to a running one.
Do you need an isolator with a DCDC charger?
The DC-DC charger would go downstream of the isolator. However, the charger is only going to work one-way. If your starter battery died and you set the isolator to allow current to flow back to the starter battery, nothing would happen. This is because the charger doesn’t charge both ways.

What cable do you use for dual batteries?
1. We suggest using 8 B&S cable for distances over 3 meters to help reduce voltage drop to the BCDC1220. As the BCDC is current limited, the larger cable is used to maintain voltage over long distances and is not for carrying extra current. 2.
Can you connect 2 12 volt batteries together?
Two or more 12-volt batteries wired in parallel—positive to positive, negative to negative—is still a 12-volt system. Two or more 12-volt batteries wired in series—the positive terminal of one battery connected to the negative terminal of a second battery—develops 24 volts, but amperage doesn’t change.
