Enerdrive ePower 20amp 12v Battery Charger EN31220

The Enerdrive ePOWER 12V 20A Battery Charger is a fully automatic, “set and forget” charger. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging technology enables the charger to be connected to your battery banks permanently. The ePower 20 amp, 12 volt smart battery charger with display and the ability to charge 3 separate battery banks. Suitable for caravans, camper trailer, motorhomes and boats. Profiles to charge GEL, AGM, Flooded, Lithium and even full custom profiles are included.



Future Proof Lithium Battery Charging - Built In

Lithium batteries require a constant current / constant voltage charge algorithm. The Enerdrive ePOWER charger has a class leading Profile for charging all types of Lithium batteries to their full potential. This setting delivers the full rated output of the charger constantly with the charger switching to power supply mode once the voltage peak is met (indicating a full battery bank). Also feature fully customisable charge rate and end voltage settings;

Select Charger Voltage Constant: 13.9, 14.0, 14.1, 14.2, 14.3, 14.4, 14.5, 14.6 Volts
Select Charger Current: 5A, 10A, 15A, 20A  - So you can charge different size batteries or battery banks
 
Industry Leading Warranty

5 Year Product Warranty & Lifetime Technical Support . They also promote a track record of near perfect resolve - Purchase any Enerdrive Product with peace of mind your covered by a company at the forefront of lithium battery systems in Australia.

 
Display Panel

The ePOWER 20A Battery Charger display gives you all the information you need for the operation of your charger. At a glance, key information such as charger amps, battery voltage and charge state continually alternate on the screen. When in float / power supply mode, the load amps are displayed so you can see exactly what the charger is doing. The display also allows you to program all settings of the charger, as well as activate the silent mode.

Silence when you need it – By pressing the “SEL” button for 5 seconds, the ePOWER Charger enters the ‘Silent’ mode that prohibits the fan from working. This ensures totally silent and safe operation at night, ideal if the charger is located close to your sleeping quarters. Silent mode limits current output to no more than 50%, and is programmed to remain on for 12 hours before automatically returning to a normal ‘fan-on & full output’ setting.

LED Display: Easy to use “set and select” menu along with scrolling charger status.
Silent Mode: Disables the cooling fan for total silent operation at night or whenever required & reduces charge output by half and locks out fan for 12 hours.
Temperature Sensor: Battery temperature sensor included with 3 meter cable.
5 Year Warranty from an Australian company renowned for customer support.

Multistage Charging Process

As dictated by battery manufacturer’s recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. Our ePOWER multistage smart 20A battery charger deliver four primary charge stages:-

Stage 1 – Bulk or Boost Charge; The battery is charged at full rated output current of the charger until the battery reaches its final charging voltage, known as its absorption voltage. In this step, around 80% of the battery capacity is recovered as fast as possible.

Stage 2 – Absorption Charge; With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its full charge.

Stage 3 – Float; Finally, in the float stage the charger voltage is lowered and held at a constant and safe predetermined level. This prevents the battery from being overcharged while supporting any additional loads connected to the battery, such as DC lighting and refrigerators. This stage allows for the charger to be used as a DC power supply.

Stage 4 – Maintenance; This stage is a regular timed “return to bulk” stage. After 7 days of constant operation in “float” the Enerdrive ePOWER Battery Charger will switch the charger from float to bulk to agitate the batteries electrolyte helping to provide an extended service life.
