The Manager30 can charge all battery types - including lithium.

Redarc’s Manager30 can charge auxiliary Lithium Ferro Phosphate (LiFePO4) batteries as well as lead acid, calcium and AGM batteries.

redarc manager30The Manager30 operates like six separate products: an auxiliary vehicle battery charger while on the move; a 240-volt charger; a solar regulator; a battery isolator; a remote battery monitor and a load-disconnect controller.

All functions display on the remote battery monitor screen.

A user-programmable load-disconnect feature allows an external relay or solenoid to be switched by the Manager30, based on battery voltage or battery state of charge.

This means that no matter the type of battery and load combination, the Manager30 can ensure that the battery can’t discharge to the point of damage.

New to the Manager30 is additional control over the load-disconnect feature. The unit now allows for deeper discharge levels, to accommodate the increased performance of LiFePO4 batteries.

There’s also a load-disconnect override, allowing the user to switch loads (such as lights) back on temporarily, in order to connect a charging source.

Green power priority means that, like its predecessor, the Manager30 has been designed to charge an auxiliary battery from multiple sources simultaneously. If 12-volt solar power input is available, solar power will be used before 240V mains or DC vehicle power.

Our current (poor pun) test phase is with the new MD30 battery management system controlling power input. That charger was fitted in January 2016 and has just completed a two-month bush trip. On that test we experienced varying weather conditions, so the charger's three-mode charging system got a workout.

We checked its operating mode several times each day and monitored battery voltage every morning, after overnight fridge operation. The lowest voltage we experienced was 13.2V.

The Manager30 used solar power whenever possible - even with 240V mains power plugged in - and our 200W mono-crystaline solar panel fed some amps into the charger nearly all the time.

Only very thick cloud reduced solar input to less than one amp, at which point the Manager30 took power for the lithium battery from the engine alternator. That happened only twice on our 10,000km trip.

The Manager30 edged slightly over its rated 30-amp charge capacity with mains or alternator input, giving a very fast recharge. However, even with typical solar input around 6.5 amps the lithium battery recovered in a couple of hours every sunny morning.

The Redarc Manager30 isn't cheap, but our first two years' testing shows that it's the best battery charger and management system we've used.

One of the OTA Team is fitting a Manager30 to a new off-road caravan where it will charge and manage two 100Ah lithium batteries. We'll keep you informed of its performance.
