Are Split charge relays any good?
A split charge relay provides an extra leisure battery charging system to your campervan. Because the kit needed to install the system is budget friendly, and the chances are you’ll be driving a fair bit, it provides a good chance to top up the batteries. We never turn down the chance for “free” power.
What does split charge mean?
Split charging is the term used to describe the simultaneous charging of the vehicle starter battery and the leisure battery (or batteries) from a common charging source.
How can I tell if my vehicle has a smart alternator?
If your readings are around 14.4V DC then you most likely have the traditional, non-smart alternator. If your reading is closer to 12.5-13.5V then it’s likely that you have a smart alternator.
Can I use a split charger with a solar panel?
With a split charge system, I’d leave it all connected and take advantage of the solar system topping both batteries once the house battery is holding 13 volts or so. That will cause the voltage sensing relay to close and also charge your engine battery.
How long does a split charge relay take to charge leisure battery?
As long as you have split charger it will charge a leisure battery in a hour but if you run it right down below 50% it will take a lot longer and may not recover.
Can you run an inverter off a leisure battery?
Inverters connect to a 12V DC supply and convert it to a 230V AC output. They allow mains appliances to be run from a leisure battery or Caravan 12 volt supply. They’re great if you’re wild camping or likely to be using sites that don’t always have a mains hook-up but they do have limitations.
Can I charge 2 leisure batteries at once?
Don’t do it. Why? It’s not a good idea to wire two batteries in parallel – yes you do get twice the capacity – but if one battery is in slightly “worse” condition or any mismatch, then the “better” battery feeds power in the other battery – and this isn’t good. The same happens when charging.
How does a smart charge alternator work?
What are ‘smart’ alternators and how do they help with emissions? Smart alternators are essentially those that have their output voltage controlled externally via the Engine Control Unit (ECU) rather than by an internal voltage regulator as found on traditional alternators.
Can I charge from alternator and solar at the same time?
You can have multiple sources charging the same battery bank at the same time. Whether it is shore power, an alternator, a generator, solar panels, etc., it doesn’t matter. Connect them all. Run them all at the same time.
Can you overcharge a leisure battery?
Leisure battery top tips summary Overcharging can be just as bad for your leisure battery as undercharging. As a general rule, never allow your leisure battery to discharge below 50 per cent of its capacity. Performance will deteriorate with age. A typical leisure battery can last as little as five years.
