12 Volt Planet

If you have a campervan, motorhome, caravan, boat or other vehicle that has a deep-cycle auxiliary or leisure battery (or batteries) installed then you will want to be able to re-charge it from mains power when available (e.g.

Fixed voltage battery chargers won't achieve full re-charging of a leisure battery because the lead plates are thicker, so charging has to take place in controlled stages with the voltage level being automatically adjusted throughout to ensure full charge absoprtion.This is where dedicated multi-stage or 'intelligent' chargers need to be used to ensure your battery receives a full, deep charge and its serviceable lifetime is maximised.

Battery-To-Battery chargers (also commonly know as DC-DC chargers) allow you to charge an auxiliary / leisure battery from your alternator whilst driving.

They are installed in-line between the positive terminals of two batteries (one of which is connected to an alternator, typically a starter battery) and offer several benefits when compared with traditional split charge systems that utilise a Voltage Sensitive Relay (VSR) or heavy-duty, alternator-triggered relay.Direct alternator charging used in a traditional split charge system with a VSR will only achieve around an 80% charge state.

DC-DC chargers (also commonly know as Battery-To-Battery chargers) with built-in MPPT Solar controllers allow you to charge an auxiliary / leisure battery from your alternator whilst driving, and from your solar panel when parked-up. These units offer the same benefits as a separate DC-DC Charger and an MPPT solar controller, but in a more compact footprint and requiring fewer cables.

These three-way chargers offer the ultimate all-in-one charging solution for your campervan or motorhome leisure batteries.

They can manage multiple charging sources thanks to their combination of a battery-to-battery (DC-DC) charger, an MPPT solar controller and a mains-powered charger, enabling you to charge from your vehicle's alternator whilst on the move, from solar panels whilst wild camping or from an AC mains hook-up whilst on-site or in storage.

Discharging your battery to very low levels can cause irreversible damage, reducing its performance and ability to hold charge. Battery guards prevent this excessive discharge by disconnecting the battery from loads in an under-voltage situation. They also disconnect the battery in an over-voltage situation, so protecting sensitive electronic appliances from damage resulting from faulty alternators or chargers.
