Twin batteries DECODED



Have you ever ever wished to arrange a 12v camp energy supply, however don’t know the place to start – we’ll break down the necessities so you realize precisely what elements you may want to collect to arrange your individual 12v tenting system.

The Journey Kings vary shares heaps of various equipment so that you can improve your setup, beginning with an very simple 12v setup all the way in which to a complete setup that’s totally self-sustaining.

Beginning with some of the fundamental setups, a easy deep cycle battery, such because the Journey Kings 115Ah AGM Battery. the thought being that you simply cost up your deep cycle battery at dwelling, and use it while you’re at camp, and easily cost your battery again up when you get dwelling. This straightforward setup will work okay for just a few days, however whenever you get to prolonged journeys away you’ll in all probability wish to contemplate a solution to tip up your batteries and replenish your power supply.


An Journey Kings Photo voltaic Panel is an extremely environment friendly solution to cost your tenting energy supply again as much as full! With greater than 9 hours of daylight shining even on the darkest winter days, There are a plethora of choices to recharge your battery, from the The Transportable 120W Photo voltaic panel which is able to outputting over 7 Amps of charging energy each hour, to an enormous 5.5KVA Generator with capabilities to cost 12v in addition to working 240V AC.

With the selection to easily ‘refuel’ your battery whenever you want it, nevertheless beginning a generator isn’t all the time an choice and also you’ll have a little bit of problem establishing your photo voltaic panel if you’re driving via the day that means your setup might not cost to its full potential. That is the place an actual true blue “twin battery” setup comes into its personal.

For individuals who might not know, a twin battery setup makes use of a relay/change between your automobiles “crank” battery this implies you utilize your car alternators large 100+ amp output could be rediverted to prime up your accent battery “mechanically” that means your campsite energy will all the time keep totally charged!

There are 2 separate methods to attach your tenting twin battery setup throughout the vary of the Journey Kings merchandise. The primary is by way of a Voltage Sensing Relay (VSR), and the second is with a DC-DC Charger. A VSR is actually a “Dumb” isolator what its roll is inside a twin battery setup is to make sure that while your car is working your alternator will maintain a cost always flowing to your auxillary deep cycle battery, till the automobiles engine is turned off. While the VSR won’t immediately change off the connection between your “crank battery” however reasonably will keep “open” till a threshold is met.

Within the case of the Journey Kings Twin Battery System the cut-out threshold is 12.8V this implies as quickly as your “Crank” and auxiliary batteries each drop to this degree they are going to be minimize off from each other.

While the VSR is ideal for older automobiles which don’t use a “sensible alternator” which is a contemporary kind of charging system that varies the alternators output to go well with the calls for of the car. Should you discover that your car makes use of a wise alternator you’re going to must get your palms on a DC-DC charger just like the CTEK D250SA which is much more intelligent than the VSR- a DC to DC charger makes use of extraordinarily intelligent circuitry to not solely isolate the 2 batteries, but additionally to cost each batteries from one another by adjusting voltage and present provide to each batteries to prime them each up, moreover, you may add an unregulated photo voltaic panel to the photo voltaic enter, and it’ll regulate and divert the voltage on to each batteries and make sure the battery with the least quantity of cost stays topped up.
