![]() 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. The display also allows you to program all settings of the charger, as well as activate the silent mode. 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 ePOWER 20A Battery Charger display gives you all the information you need for the operation of your charger. Enerdrive Battery Charger Lithium Features ePOWER Battery Charger Display The graph below shows the ePOWER charger algorithm perfectly supporting Lithium battery requirements. 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). The Enerdrive ePOWER charger can be programmed for Lithium batteries. 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. With most traditional ‘smart’ chargers their suitability to Lithium batteries is limited. The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. In the event that all 3 banks are in need of a charge, an over-ride function helps recover all 3 banks quickly and evenly before switching back to prioritise on Bank 1. Enerdrive Battery Charger Bank One Priority The priority function also 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 banks. ![]() The ePOWER 20A Battery Charger delivers a priority charge to Bank 1, or your main house battery bank which allows the charger to get this bank recharged the quickest, then transition the cycle to the lesser bank 2 & 3 batteries. 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.īank 1 PRIORITY – Charge Where You Need it Most Stage 4 – Maintenance This stage is a regular timed “return to bulk” stage. This stage allows for the charger to be used as a DC power supply. This prevents the battery from being overcharged while supporting any additional loads connected to the battery, such as DC lighting and refrigerators. In this step, around 80% of the battery capacity is recovered as fast as possible.Ībsorption Charge With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its full charge.įloat Finally, in the float stage the charger voltage is lowered and held at a constant and safe predetermined level. Our ePOWER multistage smart 20A battery charger deliver four primary charge stages:-īulk 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. As dictated by battery manufacturer’s recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. Multistage smart charging technology enables the charger to be connected to your battery banks permanently. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. The Enerdrive ePOWER 20A Battery Charger is a fully automatic, “set and forget” charger.
