In our case the extra space we gained enable us to fit a significantly larger battery - perfect for our solar panels and all those loads. As you are probably doing this because you need more capacity, it is worth checking the existing heavy-duty cables… it would be a good time to think about if the existing stuff needs upgrading too. So now we have two new identical batteries how do we go about connecting the two batteries together? You are right in your conclusion. On installation, the location of the relay is important. I am fitting a split charge Relay,and 400w of solar 2×200 panels on the roof of my camper van convention. I think I am right in saying that this is the only example I have ever come across where doing something the correct way actually looks less elegant than doing it incorrectly. If you know anyone with a caravan that has an interest and wants to learn more… pass on a link to the page.

Voltage Sensitive Split Charge Relay 12V 140A

For the main feed from leisure battery to fusebox I got myself an amplifier wiring kit which had a 50 amp cable with an inline fuse already fitted. I bought a Ford S max 4 weeks ago and when I got it home, discovered to my delight that it had a Ford Factory detachable tow bar fitted with a 13 pin swing down socket hidden underneath the bumper. Always try to use identical size cable or larger as the existing cables connecting your old battery. This is another reason why you should never connect up electrically caravan and tow vehicle with the engine running. All of the range of 140amp voltage sensitive relays are dual sensing meaning that if a charging voltage like through a mains charger or solar panel is applied to the leisure battery that exceeds the relay activation voltage of 13.

This way the two batteries will be connected as a common unit and any voltage drop on the earth cable from your earth distribution point back to the batteries will be common to both batteries and they should remain equalised. In summer you might have 12 hours of usable sunlight, about 5 of it will be overhead enough if your panel is mounted flat to be effective. However look at where the load would be connected. At times fuses spark when they fail so a battery enclosure is a recommended part of a 12V system. If we draw 100 amps from this battery bank we will effectively be drawing 25 amps from each battery.

Understanding the Leisure Battery Charging Circuit

It would be cheaper to just use a plain 30 Amp relay and link it to the vehicles ignition circuit. Leisure batteries are designed for regular discharging and re-charging unlike standard batteries. Only that one single connection has been moved. However, pins 9 and 10 become live whether the ignition is on or not. Ive decided to run the link cables between the new aux batteries in 16mm.

In this article we discuss how to recharge your camper battery from your tow vehicle and point out basic requirements as well as other recharging options. People get around this situation using a polarity reverser connection. They are both fitted with Cigarette lighter female sockets. Some things have been done for so long, in a certain manner, that it seems they must be the best way of doing it. If the voltage of the starting battery fell below a pre determined level, the split charge relay would switch back and charge the starting battery again. Do I need to run an earth lead to the chassis for both batteries? Caravan running on local mains for everything including the water heater. This can happen from the charge controller end or the alternator end.

I must say, it all makes sence when I read what you have explained. The lower the temperature the higher the charging voltage, and conversely, a higher temperature requires a lower charging voltage. The cable is available in red and 'black' actually brown , and we purchased a metre of each at a total cost of £17. The display unit shows the battery has 14. I have 2x 12volt 100ah batteries 20hour rating and connected in parallel powering 120 watts of lighting. Be sure to plan the route and locations of cable at an early stage so that you can run the cable without it being visible or having to use conduit where possible.

How to Wire up your Camper

The effects of this are rather complex and do not mean that the life of the bottom battery will be half that of the top battery, because as the bottom battery loses capacity quicker due to it being worked harder the other three batteries will start to take more of the load. A few words on battery charging Before we look at connecting batteries for split charging, it's worth taking some time to understand how a battery obtains charge from the charging source. If it is an old installation, someone may have installed a voltage sensitive relay. It is then easy to see how connecting your caravan allows the engine to charge the caravan leisure battery. If you look at the electrical drawing it should give you an idea of how to configure a set up for a winch battery. Even with the glove-box removed you will still have to reach up into a very tight space to get to the wire fed from the engine bay. If however a fuse is there and the wire shorts it will just blow the fuse.

However, if the batteries are in less than tip top condition, or they are not matched, this will reduce your viewing time. All 12V products are wired to the battery and when mains power is available the charger will replenish the battery. . Same make, Amp hour Ah rating and if you can the same manufacture date. Do you think that would introduce any issues and preclude me from running the same setup again? If so, what is the effect of pin 4 being permanently live when the tow car is connected but not running; and if not, can you explain what I should do? There should be a fuse that only goes live when the engine is running, not just when the ignition is turned on. When the engine is turned off, the solar panel regulator will respond and if the battery needs additional charge, it will provide it.

Could you suggest a 3 battery wiring diagram please?

This will ensure the system is safe and will aid when selling the vehicle. I checked all fuses and there is no separate light master switch. You also want to use these four batteries to power a 250 watt 12 volt motor that is coupled to an alternator and use that to recharge the four batteries. Conclusion The task is a simple, low-cost job that is easy to do, and well worth it if you have lots of wires going to your battery. As the battery pack increases in size, the charging period will increase too given a limited energy source.
