Concern to a 12V Guru
Possibly one item that the guru may prefer to deal with is the addition of a caravan that is second to a preexisting caravan 12V system that presently has only one household battery pack. Exactly What shall we give consideration to 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 a Jayco is suggested by me Silverline?

12V Guru answers
Many thanks for the question. Numerous RVers find one battery is not enough to service their demands, particularly for a van such as for example a Silverline where there are numerous appliances.
Get in on the batteries in parallel
To own a two battery pack set-up, you will have to get in on the batteries in ‘parallel’ where in fact the good terminals are linked together basically with all the negative. Utilize dense cable such as 8.4mm2 grizzly gay (AWG 8) and quality battery lugs. a synchronous setup increases the capability of the system in Amps and keeps the nominal voltage at 12V DC, that will be exactly what your van needs. So, two 12V 100Ah batteries joined up with this way will provide you with 200Ah capacity at 12V.
Maximise the worthiness of the large system
To increase the worthiness whenever creating a bigger system, make certain you have actually two batteries regarding the exact same chemistry, age while making. Various battery pack chemistries such as for example AGM, gel, calcium have different charging voltage requirements and also you would not obtain the two batteries correctly charged to behave as you. Likewise, a cycle that is deep in synchronous having a starter (cranking) battery pack are affected as there are construction distinctions internally during these batteries.
