30 Mar 12V Guru – add a caravan battery that is second
Concern up to a 12V Guru
Maybe one item that the guru may prefer to address is the addition of the 2nd caravan battery to a preexisting caravan 12V system that presently has only one household battery. Exactly What shall we give consideration to whenever evaluating the ability to accept the extra battery pack, selecting the new battery pack, 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. Numerous RVers find one battery isn’t enough to service their needs, particularly on a van such as for example a Silverline where there are lots of devices.
Get in on the batteries in parallel
To possess a two battery pack set-up, it is important to join the batteries in ‘parallel’ where in actuality the terminals that are positive linked together basically because of the negative. Utilize cable that is thick as 8.4mm2 (AWG 8) and quality battery lugs. a configuration that is parallel the capability of the system in Amps and keeps the nominal voltage at 12V DC, which will be exactly what your van requires. Therefore, two 12V batteries that are 100Ah in this way offers you 200Ah ability at 12V.
Maximise the worthiness of a big system
To increase the worth whenever establishing a bigger system, make sure you have actually two batteries associated with the exact same chemistry, age and also make. Different battery chemistries such as for example AGM, gel, calcium have different charging voltage needs and also you could not have the two batteries precisely charged to do something as you. Likewise, a deep period battery in synchronous having a beginner (cranking) battery pack will suffer as there are construction distinctions internally during these batteries.
Batteries obviously degrade in the long run and their capability decreases, so an adult battery pack having a brand new one will perhaps not offer performance that is optimum. Aligning these factors will permit the battery pack to work as you big bank along with cells within the condition that is same.
Failing that, a battery that is unbalanced may cause the batteries or their interior cells to not receive a straight quantity of the existing as a result of various interior opposition, which leads to some other part of battery pack bank getting various quantities of present. For instance, a bank consisting of a battery that is three-year-old with age and new a battery won’t cost evenly over the different stages of asking. Which means state of fee (SOC) will change even though the brand new battery is the exact same brand name and chemistry.
Therefore in a nutshell, to update your battery system up to a higher capacity that is amp would be most useful to buy 2 to 3 brand new batteries of the identical brand name and chemistry, utilize the more substantial quality cable, fuse accordingly and make certain your charger is effective at fulfilling your needs. To make sure the new battery bank will be with the capacity of being completely charged think about a DC-DC charger or perhaps the addition of a solar setup.
Lithium setup choice
Needless to say, there’s always the choice of upgrading the body to your latest Lithium setup Jayco has simply released, which will imply that with just www.hookupwebsites.org/datemyage-review/ one battery pack you can have twice as much Amp capacity, longer life, fewer than half the extra weight and a smaller billing time—but it comes at a price!
