Victron Blue Smart IP65 Charger 12/25A (230V)

12V smart charger • 25A max charge output • Bluetooth VictronConnect monitoring • IP65 splash and dust proof

Product Overview

The Victron Blue Smart IP65 12/25A is a high output 230V mains battery charger designed for fast charging and long term battery maintenance. It is ideal for larger 12V battery banks in caravans, camper trailers, boats, workshop vehicles, and 4WD touring setups where you want reliable charging, clear status information, and safer storage charging between trips.

Bluetooth is built in, so you can monitor charge current, battery voltage, and charge stage in the VictronConnect app. You can also review charge history and change charging profiles to suit AGM, GEL, flooded lead-acid, Calcium, and LiFePO4 batteries. The IP65-rated enclosure helps protect the charger from dust and splashes, making it well suited to real world use on the bench or mounted near your batteries.

Key Features

25A maximum charge output for faster recovery on larger 12V battery banks.
Built-in Bluetooth for setup, live monitoring, and charge history in the VictronConnect app.
7-stage adaptive charging algorithm that automatically progresses through bulk, absorption, float, and storage stages.
Select the right profile for your battery, including dedicated Li-ion mode for LiFePO4 and lead-acid profiles for AGM, GEL, flooded, and Calcium batteries.
Low current mode reduces maximum output to 10A, helping when charging smaller batteries with a high output charger.
Power supply mode can provide a stable 12V output from mains power when configured, which is useful for supporting 12V loads while working on a vehicle or system.

Accessory Compatibility Note

Important: Not all Victron IP65 accessory leads are rated for the full 25A output of the IP65 12/25 charger. Before using an accessory lead (such as cigarette plug leads, extension leads, or certain connector adapters), confirm its current rating and fuse rating suits your intended use. Using an underrated lead can cause excessive heat, nuisance fuse blowing, or damage. If you are unsure, contact Archer Batteries and we will help match the correct lead for the 12/25A charger.

Why Choose Victron IP65 12/25A?

If you are charging a larger 12V bank, the charger output current matters because it changes how quickly you can get back to a usable battery. The IP65 12/25A is designed to recharge faster than smaller workshop chargers, while still using a multi-stage algorithm that reduces battery stress once the battery approaches full charge. That is especially useful for seasonal vehicles and boats, because the charger can move into float and storage stages rather than holding the battery at higher voltages for long periods.

Bluetooth monitoring also removes guesswork. Instead of relying on basic indicator lights, you can confirm charge stage, voltage, and current from your phone, and use charge history to help identify batteries that are no longer accepting charge properly. If you want help choosing the right charger size for your battery bank, or matching accessories like eyelet leads, extension leads, carry cases, or protective bumpers, Archer Batteries can help. You can purchase online for delivery Australia-wide, or contact our team for practical advice before you order.

Choosing the Right Charger

Q: What is the Victron Blue Smart IP65 12/25A charger best used for?

It is best for charging and maintaining larger 12V battery banks where faster recharge time matters. Common uses include caravans, camper trailers, boats, workshops, and 4WD touring setups with auxiliary batteries. It can also be used for long-term maintenance charging when a vehicle or boat is parked between trips.

Q: Is 25A too big for a small car or motorcycle battery?

A 25A charger can be too high for some small batteries if you run it at full output. If you need to charge smaller batteries, use Low Current mode where available and select the correct battery profile in the app. If you are not sure, ask us and we can help match the charger to your battery capacity and battery type.

Q: Can this charger maintain a battery for long periods during storage?

Yes. The charger uses staged charging and a storage mode designed to reduce battery stress during long periods of connection. This is ideal for seasonal vehicles, boats, and standby batteries that sit for weeks at a time. It helps keep the battery ready without constant high voltage charging.

Q: What battery types can the IP65 12/25A charge?

It supports common lead-acid batteries including flooded, AGM, GEL, and Calcium. It also supports LiFePO4 when set to the lithium profile in the VictronConnect app. Always confirm your battery manufacturer charging requirements, especially for lithium batteries with a BMS.

Setup and Use

Q: How do I connect the Victron IP65 12/25A to my battery?

Connect the positive clamp or eyelet lead to the battery positive terminal, then connect the negative to the battery negative terminal. After that, plug the charger into mains power and confirm the correct battery profile is selected. For a clean install, you can leave the fused eyelet lead on the battery and plug the charger in when needed.

Q: How do I select the right mode in the VictronConnect app?

Pair your phone to the charger in VictronConnect, then choose the battery type or charging profile that matches your battery. You can also view live voltage, current, and charge stage to confirm the charger is operating as expected. If you are changing from lead-acid to lithium, verify the lithium profile is selected before charging.

Q: Can the IP65 12/25A be mounted permanently?

Yes. Many people mount it in a workshop, caravan, or boat for a tidy charging setup. Make sure it is mounted in a location with reasonable airflow and where the leads are protected from sharp edges and moving parts. If you need longer reach, use an appropriately rated accessory lead.

Charging Modes and Safety

Q: What does Low Current mode do on the IP65 12/25A?

Low Current mode reduces the maximum output so the charger is better suited to smaller batteries. This helps reduce heat and stress on small capacity batteries during charging. It is also useful when you want a gentler charge rate rather than the full 25A output.

Q: What protections does the Victron IP65 12/25A include?

It includes protections such as reverse polarity protection, short circuit protection, and thermal protection. These features help reduce the risk of damage if a mistake is made during connection or if operating conditions become too hot. Always connect clamps securely and avoid charging a damaged or leaking battery.

Accessories and Support

Q: Are all Victron IP65 accessory leads suitable for the 12/25A charger?

No. Some accessory leads and adapters are not rated for the full 25A output, and may have a lower current rating or a smaller fuse. Always confirm the accessory current rating and fuse rating matches your intended use to avoid overheating or nuisance fuse blowing. If you are unsure which lead is correct, Archer Batteries can help you choose the right accessory for the 12/25A charger.
