Intelligent Four-Stage Charging

The REGO uses an intelligent four-stage charging profile to provide controlled charging while helping maintain battery performance.

The charging stages are:

Bulk
Absorption
Float
Equalisation

The charger automatically manages these stages according to the selected battery charging profile.

35A / 510W Charging Output

With up to 35A of charging current and 510W of rated charging power, the REGO provides a convenient way to recharge your 12V leisure battery when a mains AC supply is available.

It accepts an AC input range of 180–264V at 45–65Hz, making it suitable for integration into compatible mains-powered leisure electrical systems.

Broad Battery Compatibility

The charger supports a wide range of common leisure battery technologies, including:

AGM / SLD
GEL
Flooded
Lithium
User-defined battery settings

This allows the charger to be configured to suit different battery installations rather than being limited to a single battery chemistry.

Comprehensive Electrical Protection

Built-in protection features help safeguard the charger and connected battery against common electrical and temperature-related issues.

These include over-voltage, over-current, over-temperature, low-temperature, short-circuit and reverse-connection protection.

Clear LED Status Indicators

Built-in LED indicators provide at-a-glance information about the charging process.

The indicators display charging stage, battery status and fault notifications, making it easier to check the charger’s current operating state.

Optional Bluetooth Monitoring

The REGO can be paired with the optional Renogy BT-2 Bluetooth Module to enable wireless monitoring through the Renogy App.

With the BT-2 connected, users can view real-time operating information, access charging data and adjust parameters remotely. Bluetooth is not built into the charger itself.

Compact Design

Measuring 228 × 160 × 72mm and weighing 3kg, the charger combines its 35A charging capability within a relatively compact unit for installation as part of a campervan, motorhome or off-grid electrical system.
