Enerdrive ePOWER Battery Chargers
Automatic multistage battery charger range with the ability to charge 3 separate battery banks. Suitable for charging all lithium, flooded, AGM or gel battery systems commonly found in motor home, marine, 4WD or caravan applications.
- Multistage Charging: Fully automatic multistage battery charger with the ability to charge 3 separate battery banks
- Separate Battery Banks: Isolated charging design where battery bank one is separate from battery bank two and three
- Programmable: Battery bank 1 can be programmed with a different charge algorithm over banks 2 and 3
- Current Control: User adjustable current output (e.g. Dial the 60amp unit back to run off a 1kVA generator)
- Smart Charging: The ePOWER battery charger will regulate its output based on the loads connected to your battery banks
- Wide AC Input Range: Operates on both 110V / 60Hz and 240V / 50Hz
- 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. Activation reduces charge output by half and locks out fan for 12 hours
- Temperature Sensor: Battery temperature sensor included with 3 meter cable

It’s All About Lithium
The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. With most traditional ‘smart’ chargers their suitability to Lithium batteries is limited. Lithium batteries require a constant current / constant voltage charge algorithm and are unique in that almost every amp-hour of charge delivered by the charger is accepted as one amp hour into the battery, hence the need to deliver a constant current as long as possible.
The Enerdrive ePOWER charger can be programmed for Lithium batteries. 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). As the graph shows, our ePOWER battery charger algorithm perfectly supports Lithium battery charging requirements.
Multistage Charging Process
The Enerdrive ePOWER Battery Charger is designed to quickly and accurately recharge your batteries using algorithms therefore maximising battery service life. As a result of charging battery banks using programmed algorithms, our multistage smart charging technology enables the battery charger to be connected to your battery banks permanently.
The majority of battery manufacturers recommend using a multistage charge sequence for perfect, fast and accurate charging, Enerdrive responded and focused our charger development on four primary charge stages:
Stage 1 – Bulk or Boost Charge; The battery is charged at the full rated output current of the charger until the battery reaches its final charging voltage. This is known as its absorption voltage. In this step, around 80% of the battery capacity is recovered as fast as possible.
Stage 2 – Absorption Charge; As the charger voltage held steady, the remaining 20% is replaced. This will 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 that maybe 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 Stage (3)” the battery charger will switch from Float Stage to Bulk Stage therefore agitating the batteries electrolyte. Most of all this helps to provide an extended service life for your battery banks.
Battery Bank One Priority
Charge Where You Need it Most
The ePOWER Battery Charger delivers a priority charge to Battery Bank one (or your main house battery bank) this allows the charger to get battery bank one recharged the quickest. The charger will then transition this cycle to the lesser battery banks. The priority function allows you to have a battery chemistry different to the other two, such as an AGM battery for house and lead calcium for your start batteries. In the event that all battery banks need charging, the charger has an over-ride function that recovers all three battery banks quickly and evenly before switching back to priority one or battery bank one.
LED Display Panel
The ePOWER 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.
