Product Description
Enerdrive ePOWER 12V 100A Battery Charger, 5 Year Warranty. A fully automatic "set and forget" charger designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging means it can stay connected to your battery banks permanently.
The ePOWER charger can be programmed for lithium batteries. This setting delivers the full rated output constantly, then switches to power supply mode once the voltage peak is met (indicating a full battery bank).
PRO TIP: A common accessory with this 100A charger is the 120A breaker, available in the accessory list above as an optional extra.
Features
- Multistage charging: fully automatic, charges 3 separate battery banks
- Separate battery banks: isolated design, bank one is separate from banks two and three
- Programmable: bank 1 can use a different charge algorithm to banks 2 and 3
- Current control: user-adjustable output (e.g. dial the 100A unit back to run off a 1kVA generator)
- Smart charging: regulates output based on loads connected to your battery banks
- Wide AC input: operates on 110V/60Hz and 240V/50Hz
- LED display with easy "set and select" menu and scrolling charger status
- Silent mode: disables the cooling fan for silent operation at night. Halves charge output and locks out the fan for 12 hours.
- Battery temperature sensor included with 3m cable
- 5 year warranty from an Australian company renowned for customer support
Multistage charging process
- Stage 1 – Bulk: charges at full rated current until the battery reaches its absorption voltage, recovering around 80% of capacity as fast as possible.
- Stage 2 – Absorption: voltage is held steady while the remaining 20% is replaced and current drops as the battery approaches full charge.
- Stage 3 – Float: voltage is lowered to a safe constant level, preventing overcharge while supporting loads such as DC lighting and fridges. The charger can be used as a DC power supply in this stage.
- Stage 4 – Maintenance: after 7 days in float, the charger returns to bulk to agitate the battery electrolyte, helping extend service life.
