Victron Blue Smart 4 Amp 12 Volt Battery charger with Bluetooth built in is a true smart charger and is the Professionals choice of Battery Charger, it is designed to keep your batteries in great shape. This compact design allows for easy storage and yet is powerful enough to be used for charging a car, bus, truck, caravan or boat battery system. This European designed 4 Amp 12 Volt Bluetooth Battery Charger is the latest in state of the art technology with a built in Li-ion Lithium-ion charge mode.
The Victron 4 Amp Blue Smart Battery charger is a small versatile charger that is perfect to have around home for those time when you need to give those batteries some extra maintenance, but the best part is you are able to monitor the status of of the Blue Smart Battery Charger and even control the function all via the Victron Connect App, so you have full control of the charging in your portable device phone or tablet.
The Victron 12 Volt 4 Amp Battery Charger is designed with some important features:
A lead-acid battery that that has been insufficiently charged or has been left discharged during days or weeks will deteriorate due to sulfation. If caught in time, sulfation can sometimes be partially reversed by charging the battery with low current up to a higher voltage.
Recovery function for fully discharged batteries
Most reverse polarity protected chargers will not recognize, and therefore not recharge a battery which has been discharged to zero or nearly zero Volts. The Blue Power Charger however will attempt to recharge a fully discharged battery with low current and resume normal charging once sufficient voltage has developed across the battery terminals.
Ultra high efficiency “green” battery charger
With up to 95% efficiency, these chargers generate up to four times less heat when compared to the industry standard. And once the battery is fully charged, power consumption reduces to 0,5 Watt, some five to ten times better than the industry standard.
Durable, safe and silent
- Low thermal stress on the electronic components.
- Protection against ingress of dust, water and chemicals.
- Protection against overheating: the output current will reduce as temperature increases up to 60°C, but the charger will not fail.
- The chargers are totally silent: no cooling fan or any other moving parts.
Storage mode: less corrosion of the positive plates
Even the lower float charge voltage that follows the absorption period will cause grid corrosion. It is therefore essential to reduce the charge voltage even further when the battery remains connected to the charger during more than 48 hours.
Temperature compensated charging
The optimal charge voltage of a lead-acid battery varies inversely with temperature. The Blue Smart IP65 Charger measures ambient temperature during the test phase and compensates for temperature during the charge process. The temperature is measured again when the charger is in low current mode during float or storage. Special settings for a cold or hot environment are therefore not needed.
Li-ion battery mode
The Blue Smart Charger uses a specific charging algorithm for Li-ion (LiFePO₄) batteries, with automatic Li-ion under voltage protection reset.
Water, dust and chemical resistant
Seven step smart charge algorithm
Recovery of fully discharged ‘dead’ batteries
Automatic power supply function
