High-Capacity 100A Multi-Bank Charging for Off-Grid and Marine Systems

Managing multiple battery banks in a large motorhome, caravan, or marine vessel requires a robust and intelligent power solution. The Enerdrive ePower 12V 100A Battery Charger is specifically engineered to handle heavy power demands, providing fully automatic multistage charging for up to three separate battery banks simultaneously. With a powerful 100A output, it rapidly replenishes high-capacity storage systems, ensuring reliable power for demanding off-grid applications.

Important charging profile note: Battery bank 1 can be programmed independently and is intended as the priority or main battery bank, while battery banks 2 and 3 share the same charging algorithm rather than being configured separately. This means the charger can support a mixed setup such as bank 1 on lithium and banks 2 and 3 on AGM, however banks 2 and 3 must use the same battery profile. Once charging is complete, all three banks then move to a shared float stage determined by the bank 1 setting, so mixed-chemistry installations should always be matched against the battery manufacturers’ recommended charging requirements.

Key Performance Features

• 100A Maximum Output: Rapidly recharges large battery banks, with user-adjustable current control to suit smaller generators.
• Broad Battery Compatibility: Selectable profiles for Lithium, AGM, Gel, and Flooded chemistries.
• Wide AC Input Range: Operates seamlessly on 100-240 VAC, making it ideal for variable generator power or international marina shore power.
• Heavy-Duty Connections: Equipped with robust 8mm (Approx. M8) thread terminals for secure, low-resistance cable installation.
• Thermal Management: Includes a battery temperature sensor to automatically adjust charging parameters and protect your battery investment.

Priority Charging for Your House Bank

The ePower 100A multibank charger features an intelligent Bank 1 priority system. Recognising that your primary house battery typically experiences the deepest discharge, the charger focuses its initial output on Bank 1 to recover capacity as quickly as possible. Once the primary bank reaches a stable state, the charger smoothly transitions to maintain the auxiliary banks (Banks 2 and 3). Furthermore, Bank 1 can be programmed with a different charge algorithm than Banks 2 and 3, giving you total flexibility over mixed-chemistry battery arrays.

Optimised for Lithium Batteries

Modern off-grid systems increasingly rely on high-capacity lithium (LiFePO4) batteries, which require specific charging parameters. Standard smart chargers often fail to deliver the sustained current required by lithium cells. The Enerdrive ePower charger includes a dedicated lithium profile that delivers a constant current for as long as possible, ensuring every amp-hour is efficiently absorbed. Once the peak voltage is reached, the unit switches seamlessly to a power supply mode, perfectly supporting lithium battery requirements without the risk of overcharging.

Intelligent Multistage Charging Process

To maximise the lifespan of your deep-cycle batteries, the charger employs a sophisticated four-stage algorithm:

• Bulk Charge: Delivers the full rated 100 amp charger output to rapidly restore approximately 80% of the battery's capacity.
• Absorption Charge: Holds the voltage steady while current tapers off, safely pushing the battery to a 100% state of charge.
• Float Stage: Lowers the voltage to a safe maintenance level, preventing overcharging while acting as a DC power supply for active loads like refrigerators or lighting.
• Maintenance Stage: Automatically returns to the bulk stage after seven days of continuous float operation, agitating the electrolyte in traditional batteries to extend service life.

Silent Mode for Night-Time Comfort

Installing a high-output charger inside a caravan or boat cabin often introduces unwanted fan noise. The Enerdrive ePower solves this with a dedicated Silent Mode. By pressing a single button on the backlit LCD display, the thermo-controlled cooling fan is disabled for 12 hours. The charger automatically halves its output to prevent overheating, ensuring totally silent and safe operation while you sleep.
