Dual Battery System | Necessary Points to consider
A dual battery system increases your power stores by boosting your 12 voltage battery capacity, and is often achieved by adding another battery in parallel with your main cranking battery power. The system can also verify safe and reliable battery charging from vehicle alternator or solar power systems. Even so, to be sure a trouble-free dual battery system there is some common faults to avert.
1. Combining different battery types is not highly recommended. Batteries come in numerous kinds that are fabricated to accomplish specific functions. Do your thorough web research. My recommendation is the AGM battery that presents excellent attributes when used in a deep cycle mode and at a push can be used as a good battery.
2. Departing your parallel hooked up batteries unprotected is seeking trouble. The further apart your batteries are from each other the higher the risk of a short-circuit someplace. It may look like overkill but my suggestion is to have a 100 Amp in-line fuse in the positive cable at each battery.
3. Abandoning your primary turning battery linked to the additional battery permanently is not a good option either. The risk is that the turning battery becomes released leaving your car or truck - and you, stuck. One formula is to have to start up the dashboard that disconnects the cranking battery from the auxiliary, but exactly what goes on whenever you forget to flick the switch? Preferable to install a voltage sensitive relay that just hooks up the batteries together when the turning battery has reached charge and immediately disconnects should the voltage fall below a predetermined level.
4. By using little electrical circuitry in a dual battery system will avert it from performing thorough. Figure out your optimal current draw, allowable voltage drop, and opt for cable measurement to match those constraints. For a second time, do your search for. Various countries describe cable sizes in different ways. Always go a size above that wanted to make certain.
