Multiple battery protection features like external temperature sensor, absorption time limiter, and initial battery charge acceptance test.
Use as a stand alone 13.8V/25A power supply.
Fully Australian complianced (c-tick and electrical safety approval number).
High quality of all components and workmanship.
Two year warranty.
Extremely competitive pricing.

I'm glad to answer any questions you might have, pls read on for more details:

It's a top of the line 12V/25A charger for a range of batteries.
It is an 'intelligent multi stage' design. Plus, it offers some very welcome means of manual tweaking, to make it perform according to the battery specifications, no matter which batteries are concerned or which operating environment it'll run in.

It starts with taking the guesswork out, which charging regime the charger will apply, because it lets you manually adjust the battery type/charging voltage.
Charge up to three separate batteries at the same time, e.g. starter battery, as well as two deep cycle AGM batteries. The batteries don't need to have the same capacity rating and/or SOC.
E.g. you can connect one AGM 100Ah at 50% SOC to battery output 1, and another AGM 60Ah at 10% SOC to battery output 2 and the charger will perfectly recharge both of them.

Then there is the 1 amp 12V starter battery maintenance output: never let small loads (like car stereo, cabin lights) drain your starter battery. The 1A 13.8V maintenance output restores full charge in your starter battery, while charging your second/house batteries.

Half power mode: this is an extremely useful feature for charging smaller capacity batteries, as they won't be subjected to the brutally high 25A bulk charge current, which is something for their 100Ah+ brothers.

When travelling, you can use a small inverter to power your charger in half power mode. The alternator/starter battery/inverter will benefit from 50% reduced current demand, especially under high ambient temperatures.
This way, you can perfectly recharge any battery up to 14.8V, via the 12V on-bord system.

Another scenario is that you could tap into an existing small solar setup, which charges your starter battery at anywhere between 11 and 14.4V.
Your inverter/charger (in half power mode) will now perfectly precision-charge any type of house battery up to 14.8V - no matter how badly regulated your solar setup is.
In fact, you can use any means of recharging your starter battery, including generator, solar, alternator - as the starter battery will now act as an energy buffer for your precision charging of the more picky deep cycle house batteries.

3 ways of battery protection:

Temperature compensation of all charging voltages/stages, by external battery temperature sensor.
Chargers lacking this all important feature will shorten battery life dramatically in our high summer temperature environment. On the other hand, during use in cold winters, sulfation can result, if the voltages are not increased accordingly.
Automatic battery test before boost charge ramp up:
This effectively prevents overheating of a weak battery, as the increased internal resistance won't allow for high rate boost charging, without further weakening the battery.
Adjustable time limits for boost/absorption stage:
Note that this feature can prevent your valuable battery from being seriously overcharged in the following very common scenario:
Your house battery is connected to your fridge, which will draw current in irregular intervals.
Multi stage chargers are meant to reduce the charging voltage after the absorption stage has finished. The chargers therefore measure the charging current, and only if it has tapered off by 90%, the charging voltage will be switched over to the float charge level.
As you can imagine, any load currents will fool the charger, because it has no means of telling load currents from battery currents.
Our state of the art charger effectively prevents this from happening by applying a (manually configurable) time limit to the bulk/absorption stage. In case the switch-over point goes unnoticed, the high current charging will run into the preset time limit.
The charger will now force itself to reduce the higher boost output voltage to the float level.

Other nice features:

True 14.8V boost charge voltage standard, for Asian made AGM batteries (while keeping the 14.4V as a switch selection).
Compared to 14.4V of some very popular chargers, 14.8V allows for quicker charging as the 25A bulk current will now push the SOC to a higher level, before the battery starts to cut down it's current intake.
Heavy duty battery clamps, and AWG #8 charging wires standard.
Quiet fan only runs during high charge current demand.
Polarity mismatch and short circuit protection.
13.8V power supply function, with or without battery connected.
Built in power factor correction means less heating inside your generator thus less fuel use.
Built and certified to Australian EMC standards (c-tick).
As a result, this charger is a little heavier than the competition's due to a significant amount of additional filter components in the form of iron cored copper coils (3.5kg).
Built and certified to Australian electrical safety standards (consider that fire and personal injury insurance cover are only effective with this type of certification).
