12 Volt 5 Amp Hour Blue Smart Charger - IP65 by Victron

Victron's Blue Smart IP65 charger is a battery charger with built-in Bluetooth transmitter. The Blue Smart IP65 can be used with equipment in your workshop or with motor vehicles such as (classic) cars, motorcycles, boats and caravans. The seven-step charging algorithm gets the best out of your battery. The charger provides the battery with the energy it needs, ensuring optimal performance and longer life. Unlike other devices, the Blue Smart IP65 will attempt to recharge a deeply discharged battery by forcing a weak charging current on it. Normal charging operation will then resume as soon as there is sufficient voltage between the battery terminals. The Bluetooth transmitter allows you to check the status of the charger and battery on a smartphone or computer. All charger settings can be configured using the VictronConnect App. As the charger is supplied with both crocodile clips and M8 cable lugs, connection to the battery is very easy. You can always leave the unit connected if you wish.
