12V Guru – add a 2nd caravan battery pack
Concern up to a 12V Guru
Maybe one item that the guru may prefer to address is the addition of the caravan that is second to a preexisting caravan 12V system that currently only has one household battery pack. Just What shall we think about whenever assessing the capacity to accept the battery that is additional selecting the new battery pack, as well as the fitting and wiring? For reference caravan https://hookupwebsites.org/bondage-com-review/, may i recommend a Jayco Silverline?
All the best, Bob Murray

Thank you for the question. Numerous RVers find one battery is not adequate to service their needs, particularly for a van such as for example a Silverline where there are numerous devices.
Get in on the batteries in parallel
To possess a two battery pack set-up, you need to join the batteries in ‘parallel’ where in actuality the good terminals are connected together basically using the negative. Utilize cable that is thick as 8.4mm2 (AWG 8) and quality battery pack lugs. a parallel configuration increases the ability of the system in Amps and keeps the nominal voltage at 12V DC, which can be what your van needs. Therefore, two 12V batteries that are 100Ah this way provides you with 200Ah ability at 12V.
Maximise the worth of a big system
To increase the worthiness when creating a bigger system, make sure you have actually two batteries associated with the exact same chemistry, age and then make. Various battery pack chemistries such as for instance AGM, gel, calcium have different charging voltage needs and you also could not have the two batteries precisely charged to behave as one. Likewise, a deep cycle battery in synchronous having a starter (cranking) battery pack are affected as you can find construction distinctions internally during these batteries.
Batteries obviously degrade as time passes and their capability decreases, so a mature battery pack having a brand new one will likely not offer maximum performance. Aligning these factors will enable the battery to use as you big bank along with cells into the condition that is same.
Failing that, an unbalanced battery pack bank can cause the batteries or their interior cells never to get a much number of the existing because of the various internal resistance, which leads to various areas of battery pack bank getting various quantities of present. For instance, a bank composed of a battery that is three-year-old with age and brand new a battery won’t fee evenly over the different phases of asking. Which means state of charge (SOC) will be different regardless of if the battery that is new the exact same brand name and chemistry.
Therefore simply speaking, to update your battery pack system to a higher Amp ability it would be best to purchase 2 to 3 new batteries of the same 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 certain the new battery pack bank will be with the capacity of being fully charged look at a DC-DC charger or even the addition of the solar setup.
Lithium setup choice
Needless to say, there’s always the choice of updating your system towards the latest Lithium setup Jayco has simply released, which may imply that with only one battery you might have double the Amp capacity, longer life, fewer than half the extra weight and a shorter asking time—but it comes down at a price!
