Concern up 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 has only one household battery pack. Exactly What shall we think about whenever evaluating the capacity to accept the battery that is additional seeking the new battery pack, plus the fitting and wiring? For guide caravan, may i will suggest a Jayco Silverline?

All the best, Bob Murray

12V Guru answers

Thank you for the concern. Many RVers find one battery is not adequate to service their demands, specially for a van such as for example a Silverline where there are numerous devices.

Get in on the batteries in parallel

To own a two battery set-up, you will have to get in on the batteries in ‘parallel’ in which the terminals that are positive linked together basically utilizing the negative. Utilize cable that is colombiancupid profile search thick as 8.4mm2 (AWG 8) and quality battery lugs. a synchronous setup increases the capability of one’s system in Amps and maintains the nominal voltage at 12V DC, which can be exactly what your van needs. So, two 12V 100Ah batteries joined in this way provides you with 200Ah capability at 12V.

Maximise the worth of the system that is large

To increase the worth whenever establishing a bigger system, make certain you have two batteries for the same chemistry, age and work out. Various battery pack chemistries such as for example AGM, gel, calcium have different charging voltage needs and you also could not have the two batteries precisely charged to do something as you. Likewise, a cycle that is deep in synchronous with a beginner (cranking) battery pack will suffer as you can find construction distinctions internally in these batteries.

Batteries obviously degrade with time and their ability decreases, so an adult battery pack with a brand new one will likely not provide maximum performance. Aligning these facets will enable the battery pack to work as you large bank along with cells within the condition that is same.

Failing that, a battery that is unbalanced will cause the batteries or their interior cells to not receive a straight quantity of the present as a result of various interior opposition, which leads to some other part of battery pack bank receiving various quantities of present. For instance, a bank composed of a three-year-old battery degraded with age and brand brand new a battery won’t cost evenly over the different stages of charging. And so the state of charge (SOC) will be different regardless if the brand new battery pack is the exact same brand name and chemistry.

Therefore in a nutshell, to update your battery pack system to a higher Amp ability it might be best to purchase 2 to 3 new batteries of the identical brand name and chemistry, utilize the weightier quality cable, fuse accordingly and guarantee your charger is effective at fulfilling the needs you have. To make sure your brand-new battery pack bank will be effective at being completely charged look at a DC-DC charger or the addition of the solar setup.

Lithium setup choice

Needless to say, there’s always a choice of updating one’s body towards the latest Lithium setup Jayco has simply released, which may imply that with only 1 battery pack you might have twice as much Amp capacity, longer life, fewer than half the extra weight and a smaller recharging time—but it comes down at a high price!
