Concern to a 12V Guru

Possibly one item that the guru may prefer to deal with is the addition of the caravan that is second to a preexisting caravan 12V system that presently just has one home battery pack. Just exactly What shall we start thinking about whenever evaluating the ability to accept the battery that is additional seeking the new battery, plus the fitting and wiring? For guide caravan, may a Jayco is suggested by me Silverline?

All the best, Bob Murray

12V Guru answers

Many thanks for your question. Numerous RVers find one battery is not adequate https://www.hookupwebsites.org/christian-dating-for-free-review to service their demands, particularly on a van such as for instance a Silverline where there are lots of devices.

Get in on the batteries in parallel

To possess a two battery pack set-up, you need to get in on the batteries in ‘parallel’ where in fact the good terminals are connected together basically utilizing the negative. Utilize cable that is thick as 8.4mm2 (AWG 8) and quality battery pack lugs. a configuration that is parallel the capability of one’s system in Amps and maintains the nominal voltage at 12V DC, which will be exactly what your van needs. So, two 12V batteries that are 100Ah this way provides you with 200Ah capacity at 12V.

Maximise the worthiness of the system that is large

To increase the worthiness whenever creating a more substantial system, make certain you have two batteries associated with the same chemistry, age while making. Various battery pack chemistries such as for example AGM, gel, calcium have different charging voltage needs and also you would not obtain the two batteries precisely charged to do something as you. Likewise, a cycle that is deep in parallel with a beginner (cranking) battery pack are affected as you can find construction distinctions internally in these batteries.

Batteries obviously degrade in the long run and their capability decreases, so an adult battery with a brand new one will likely not offer maximum performance. Aligning these facets will let the battery pack to use as one big bank along with cells within the exact same condition.

Failing that, an unbalanced battery pack bank may cause the batteries or their interior cells never to receive a much number of the existing as a result of the various interior opposition, which leads to some other part of battery pack bank receiving different amounts of current. As an example, a bank composed of a three-year-old battery degraded with age and brand new a battery won’t cost evenly throughout the different stages of charging. And so the state of charge (SOC) will be different just because the new battery pack is exactly the same brand name and chemistry.

Therefore simply speaking, to upgrade your battery pack system to a higher Amp ability it would be most useful 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 guarantee your charger is effective at fulfilling your needs. To make sure your brand-new battery pack bank will be effective at being fully charged consider a DC-DC charger or even the addition of the setup that is solar.

Lithium setup choice

Of course, often there is the choice of updating one’s body to your latest Lithium setup Jayco has simply released, which may imply that with only 1 battery pack you can have twice as much Amp capacity, longer life, not even half the extra weight and a smaller billing time—but it comes down at a price!
