Projecta IC25RV Battery Charger 12V 25 Amp 7 Stage RV Multi Chem Lithium

Projecta IC25RV Battery Charger 12V 25 Amp 7 Stage RV Multi Chem Lithium

Fully automatic 12V 25A 7-stage RV battery charger with multi-chemistry compatibility covering lithium, AGM, GEL, and conventional wet batteries, adjustable output for different battery sizes, power supply mode, wired remote control, and spark-free polarity protection, backed by Projecta's 5-year warranty for caravans, motorhomes, and RV applications.

Product Overview

The Projecta IC25RV is a professional-grade 12V 25-amp automatic battery charger designed specifically for RV, caravan, and motorhome applications where reliable multi-chemistry charging across a range of battery types and sizes is essential. The 7-stage charging algorithm delivers a comprehensive charge and conditioning cycle that optimises battery health, maximises capacity restoration, and extends battery lifespan beyond what basic 2 or 3-stage chargers can achieve. The multi-chemistry capability covers all major battery types commonly used in modern RV and caravan builds — including lithium (LiFePO4), AGM, GEL, and conventional wet lead-acid batteries — making the IC25RV a single charger solution across an entire fleet or vehicle inventory without requiring battery-type-specific charger variants. The adjustable output function allows the charger to be configured for different battery bank sizes, ensuring the charge rate is appropriate for the battery capacity being charged and preventing undercharging of large banks or overcharging of smaller batteries. Power supply mode converts the IC25RV into a stable DC power supply, enabling 12V equipment to be run from mains power without battery involvement — useful for workshop diagnostics, caravan accessory testing, and electronic system maintenance while connected to shore power. The wired remote control provides the ability to operate and monitor the charger from a convenient location away from the battery bank, particularly valuable in caravans and motorhomes where the battery compartment may be inaccessible during charging. Spark-free operation and polarity protection safeguard against wiring errors and connection arcing, and the shock and dustproof construction ensures reliable performance in the under-vehicle, storage bay, and outdoor environments typical of RV charging setups. Projecta's 5-year warranty reflects the build quality and long-term reliability expected from one of Australia's most established battery charger brands.

Features & Benefits

7-Stage Automatic Charging Algorithm: The 7-stage charging cycle delivers a comprehensive charge, conditioning, and maintenance program that optimises battery state of charge, desulphates lead-acid plates, balances cell voltages, and maintains batteries at full capacity — significantly extending battery lifespan compared to basic multi-stage chargers.

Multi-Chemistry Compatibility: Supports lithium (LiFePO4), AGM, GEL, and conventional wet lead-acid battery chemistries in a single charger unit, providing a versatile single-unit solution for RV and caravan builds running any combination of battery types across house banks and starting batteries.

25A Output for Rapid Charging: The 25A charge output provides rapid charge restoration for large caravan and motorhome house battery banks, significantly reducing the time required to restore a discharged bank to full capacity compared to lower-output chargers.

Adjustable Output for Different Battery Sizes: The adjustable output function configures the charge rate to suit the capacity of the battery bank being charged, ensuring optimal charge current for both small auxiliary batteries and large multi-battery house banks without the risk of under or overcharging.

Power Supply Mode: Converts the charger into a stable 12V DC power supply for running 12V equipment directly from mains power, useful for caravan accessory testing, workshop diagnostics, and electronic system maintenance without requiring a live battery in circuit.

Wired Remote Control: The wired remote control provides operation and monitoring capability from a location away from the battery compartment, particularly valuable in caravans and motorhomes where the battery bay is under the floor or in an inaccessible storage compartment during charging.

Spark-Free Operation: Eliminates connection arcing during clamp or cable attachment to the battery terminals, reducing the risk of igniting battery gases in enclosed battery compartments and storage bays.

Polarity Protected: Electronic polarity protection prevents damage to the charger and battery in the event of reverse connection, safeguarding against wiring errors during installation or reconnection after maintenance.

Shock and Dustproof Construction: Robust housing withstands the physical demands of RV storage bay, under-vehicle, and workshop environments subject to dust, vibration, and incidental impacts.

Fully Automatic Operation: Once connected and configured, the IC25RV operates through its full 7-stage cycle and transitions to a maintenance float charge automatically without requiring manual intervention, protecting the battery from overcharging during extended storage periods.

Projecta 5-Year Warranty: Backed by Projecta's 5-year warranty, providing long-term confidence for caravan and RV owners, fleet operators, and workshop professionals specifying a reliable multi-chemistry charger for ongoing use.

Frequently Asked Questions

What does the 7-stage charging algorithm do that basic chargers cannot?

A basic 2 or 3-stage charger performs bulk charging followed by a simple absorption and float phase. The IC25RV's 7-stage algorithm adds desulphation, soft start, analysis, equalisation, and conditioning stages that progressively restore battery capacity, remove sulphation build-up from lead-acid plates, balance cell voltages, and verify battery health before and after charging. This comprehensive cycle maximises the usable capacity restored per charge and significantly extends battery lifespan, particularly for batteries that have been deeply discharged or left in a partially charged state over extended periods.

What is power supply mode and when would I use it?

Power supply mode bypasses the battery charging algorithm and converts the IC25RV into a stable 12V DC power supply output. This allows 12V caravan appliances, accessories, and electronic systems to be powered directly from mains power without requiring a battery in the circuit — useful for testing caravan lighting and appliances during a workshop service, running accessories during storage when the battery has been removed, and diagnosing electrical faults without a live battery present. Confirm the connected load does not exceed the 25A maximum output current in power supply mode.

Does the IC25RV charge lithium LiFePO4 batteries safely?

Yes. The IC25RV includes a dedicated lithium (LiFePO4) charging profile that applies the correct charge voltage and current profile for lithium iron phosphate chemistry. Charging lithium batteries with a charger that does not have a specific lithium profile can result in undercharging, overcharging, or BMS protection trips. Always select the lithium chemistry setting when charging LiFePO4 batteries to ensure the correct voltage parameters are applied for safe and complete charging.

What is the wired remote control used for?

The wired remote control allows the charger to be operated and monitored from a location away from the battery installation, particularly useful in caravans and motorhomes where the battery compartment is under the floor, in an external storage bay, or behind a panel that is inconvenient to access during charging. The remote provides the ability to select battery chemistry, adjust output, monitor charge status, and control the charger without needing physical access to the unit itself.

What size battery bank is the IC25RV suitable for?

The IC25RV's adjustable output and 25A maximum charge current make it suitable for a wide range of battery bank sizes. As a general guideline, a charge current of approximately 10–20% of the battery's amp-hour capacity is recommended for optimal charging — meaning the IC25RV is well matched to battery banks from approximately 50AH up to 250AH and beyond, with the adjustable output allowing the charge rate to be set appropriately for the specific bank size. Consult the IC25RV instruction manual or contact Projecta for specific recommendations for very large multi-battery bank installations.
