Connect the battery bank to your electrical system. From one of the end batteries, connect the positive and negative posts to the fuse or breaker panel of your 12-volt electrical system. The life of the batteries' charge depends on the number of amps you use and the amount of time you draw from the battery. Three 200-amp hour batteries, 600 total amp hours, for example, power a television that draws 100 amps for six hours.
Whether electricity were a vehivle, the voltage would be its celerity. But, provided you demand to augmentation the bigness of faculty available to you, a equal battery connexion is the system to get-up-and-go. Using the prior model, three 12-volt, 200 amp-hour batteries connected in paralell yet onliest create 12 volts of electricity nevertheless Testament effect so for 600 amp hours. Amperage is a degree of the energy available.
In the van plot, amperage would be compatible petrol. Multiple batteries connected in equal are fine on boats or recreational vehicles that don't compass access to shore authority. Depending on your amperage needs, a parallel-connected battery bank can grasp your lights on and your refrigerator running for hours or yet days.
Instructions
1. Choose the fitting batteries. In course for a equal connexion to function safely and efficiently, the batteries you exercise in the battery bank must all be of the equivalent type wet-cell or gel cell, deep-cycle or cranking and hurried in lifetime. Older batteries are repeatedly worn and differ significantly in ability from initial specifications. Far cycle, gel cell batteries exertion first for long-term, efficient energy storage.
2. Select the correct cables. Use different colors for positive and negative; red is a very common color for positive cables, whereas black or white are typically used to denote the negative current. For a 12-volt electrical system on a boat or camper, use wires between 10 and 14 gauge. Wire of this gauge can handle the voltage from the batteries with little enough resistance to ensure your electrical system operates efficiently.
3. Connect the positive battery posts. Connect the wire or cable you've selected for the positive current from the positive post of the first battery to the positive post of the second battery. If you are using more than two batteries, continue until the positive posts of each battery are connected to the positive post of the battery immediately before it. Batteries on the ends of the bank should only have one wire connected to their positive posts; batteries in the middle should have two wires connected to their positive posts: one from the battery before and one to the battery after.
4. Connect the negative battery posts. Just like the positive posts, connect the wire or cable you've selected for the negative current from the negative post of the first battery to the negative post of the second battery, from the second battery to third, from the third battery to the fourth, and so on. Again, batteries on the ends of the bank should only have one wire connected to their negative posts; batteries in the middle should have two wires connected to their negative posts: one from the battery before and one to the battery after.
5.Connect 12V Batteries in ParalellWhether you entail to escalation the standard of efficacy outlook from a battery bank, connect your batteries in series. For instance, three 12-volt, 200 amp-hour batteries connected in series create 36 volts at 200 amp hours of call. Voltage is a measurement of the degree that strength moves from the batteries. Different devices obviously draw different amperages. If you ran nothing but lights, which are relatively efficient, the system charge could last for days. Throw in a blow-dryer and the life of the system charge is drastically reduced.
