Concern to a 12V Guru
Possibly one item that your particular guru may prefer to deal with is the addition of a 2nd caravan battery pack to a preexisting caravan 12V system that presently has only one home battery pack. Just exactly What shall we start thinking about whenever evaluating the ability to accept the battery that is additional selecting the new battery, as well as the fitting and wiring? For guide caravan, may i recommend a Jayco Silverline?
All the best, Bob Murray
12V Guru answers
Thank you for the question. Many RVers find one battery is not enough to service their demands, particularly for a van such as for example a Silverline where there are numerous appliances.
Get in on the batteries in parallel
To possess a two battery pack set-up, it is important to join the batteries in ‘parallel’ in which the positive terminals are linked together basically with all the negative. Utilize cable that is thick as 8.4mm2 (AWG 8) and quality battery lugs. a configuration that is parallel the capability of one’s system in Amps and keeps the nominal voltage at 12V DC, which can be exactly what your van requires. Therefore, two 12V batteries that are 100Ah in this manner will provide you with 200Ah capacity at 12V.
Maximise the worthiness of a system that is large
To maximise the worth whenever installing a bigger system, make sure you have actually two batteries of this chemistry that is same age and then make. Various battery pack chemistries such as for instance AGM, gel, calcium have different charging voltage requirements and also you could not have the two batteries precisely charged to behave as you. Likewise, a cycle that is deep in synchronous having a beginner (cranking) battery pack are affected as you can find construction distinctions internally in these batteries.
Batteries naturally degrade in the long run and their capability reduces, so a mature battery with a brand new one will likely not offer performance that is optimum. Aligning these factors will enable the battery pack to operate as you large bank with all cells within the condition that is same.
Failing that, a battery that is unbalanced may cause the batteries or their interior cells to not ever get a much number of the existing as a result of various internal opposition, which leads to some other part of the battery pack bank getting different levels of current. For instance, a bank composed of a three-year-old battery degraded with age and new a battery won’t fee evenly throughout the different phases of asking. And so the state of charge (SOC) will change regardless if the battery that is new the exact same brand name and chemistry.
Therefore in short, to upgrade your battery pack system up to a higher capacity that is amp might be best to purchase 2 to 3 brand brand new batteries of the same brand name and chemistry, make use of the weightier quality cable, fuse accordingly and make certain your charger is with the capacity of fulfilling your needs. To make certain the new battery bank will be effective at being completely charged consider a DC-DC charger or even the addition of the solar setup.
Lithium setup option
Needless to say, there’s always a choice of upgrading the body into the latest Lithium setup Jayco has simply released, which may imply that with just one battery pack you might have twice as much Amp capacity, longer life, not even hookupwebsites.org/tendermeets-review half the extra weight and a shorter billing time—but it comes down at a high price!
