Question up to a 12V Guru
Maybe one item that the guru may love to address is the addition of a caravan that is second to a preexisting caravan 12V system that presently has only one household battery pack. What shall we think about when assessing the ability to accept the extra battery pack, selecting the brand brand new battery pack, as well as the fitting and wiring? For reference caravan, may i would recommend a Jayco Silverline?
All the best, Bob Murray
12V Guru answers
Thank you for your question. Numerous RVers find one battery is not adequate to service their needs, particularly for a van such as for instance a Silverline where there are lots of devices.
Join the batteries in parallel
To possess a two battery set-up, you will have to join the batteries in ‘parallel’ where in actuality the terminals that are positive linked together basically aided by the negative. Utilize cable that is thick as 8.4mm2 (AWG 8) and quality battery pack lugs. a configuration that is parallel the ability of one’s system in Amps and keeps the nominal voltage at 12V DC, which can be exactly what your van needs. Therefore, two 12V 100Ah batteries joined up with this way provides you with 200Ah capability at 12V.
Maximise the worthiness of a system that is large
To increase the worthiness whenever starting a more substantial system, make certain you have actually two batteries for the chemistry that is same age while making. Various battery pack chemistries such as for instance AGM, gel, calcium have different charging voltage needs and you also would not obtain the two batteries precisely charged to do www.hookupwebsites.org/ukraine-date-review/ something as you. Likewise, a cycle that is deep in synchronous with a beginner (cranking) battery are affected as you can find construction differences 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 performance that is optimum. Aligning these facets will let the battery pack to use as you big bank along with cells into the exact same condition.
Failing that, an unbalanced battery pack bank may cause the batteries or their interior cells not to ever get a level quantity of the existing because of the various interior opposition, which leads to various areas of the battery pack bank getting various degrees of current. For instance, a bank composed of a battery that is three-year-old with age and brand brand new a battery won’t charge evenly throughout the various phases of asking. And so the state of fee (SOC) will be different whether or not the brand new battery pack is the exact same brand name and chemistry.
Therefore simply speaking, to update 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 identical brand name and chemistry, make use of the weightier quality cable, fuse accordingly and make certain your charger is with the capacity of meeting the needs you have. To make sure the new battery pack bank will be with the capacity of being completely charged look at a DC-DC charger or the addition of a solar setup.
Lithium setup option
Of course, often there is the choice of updating one’s body to your latest Lithium setup Jayco has simply released, which will imply that with only 1 battery pack you might have double the Amp capacity, longer life, not even half the extra weight and a smaller charging time—but it comes down at a price!
