12V Guru – add a second caravan battery pack

Concern up to a 12V Guru

Possibly one item that the guru may prefer to deal http://www.hookupwebsites.org/bicupid-review with is the addition of a 2nd caravan battery pack to a preexisting caravan 12V system that presently just has one home battery. just What shall we give consideration to whenever evaluating the capacity to accept the battery that is additional selecting the brand brand new battery, as well as the fitting and wiring? For guide caravan, may a Jayco is suggested by me 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 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 own a two battery set-up, you need to get in on the batteries in ‘parallel’ where in fact the good terminals are linked together and likewise aided by the negative. Utilize dense cable such 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, that will be exactly what your van requires. Therefore, two 12V 100Ah batteries joined up with in this way offers you 200Ah capability at 12V.

Maximise the worth of the large system

To increase the worth when creating a more substantial system, make sure you have actually two batteries regarding the exact same chemistry, age and work out. Various battery pack 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 behave as you. Likewise, a deep period battery in parallel having a beginner (cranking) battery pack are affected as you can find construction distinctions internally in these batteries.

Batteries obviously degrade as time passes and their ability reduces, so an adult battery pack 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 in the same condition.

Failing that, a battery that is unbalanced may cause the batteries or their internal cells to not ever get a straight quantity of the existing because of the various internal opposition, which leads to various areas of battery pack bank getting different quantities of present. As an example, a bank composed of a three-year-old battery degraded with age and brand new a battery won’t cost evenly over the different phases of billing. Which means state of fee (SOC) will change regardless of if 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 capacity that is amp might be best to purchase 2 to 3 brand new batteries of the identical brand name and chemistry, make use of the more substantial quality cable, fuse appropriately and make sure your charger is with the capacity of fulfilling your needs. To make certain the new battery bank will be effective at being completely charged think about a DC-DC charger or the addition of the solar setup.

Lithium setup choice

Needless to say, there's always a choice of updating your body into the latest Lithium setup Jayco has just released, which will imply that with just one 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!
