Vapcell SU2 – powerful 2-slot quick charger for Li-Ion, LiFePO4, NiMH/NiCd and 1.5V Li-Ion batteries

The Vapcell SU2 is a powerful universal charger for a wide range of modern battery types and has been specially developed for users who want to charge their batteries reliably and in a controlled manner. With two independently operating charging bays, precise charge monitoring and a wide adjustable charging current range, the charger is suitable for everyday use as well as for demanding applications in the hobby or technical sector.

High charging current and flexible current selection for many cylindrical batteries

In addition to the classic charging process, the Vapcell SU2 offers flexible current control in auto or manual mode. In auto mode, the charging current is automatically assigned based on the measured internal resistance, while in manual mode the charging current can be selected specifically. This allows the charging behaviour to be adapted to different cell types and areas of application. (1.5V Li-Ion: charging function only, charging current not freely adjustable).

Universal charger for Li-ion, LiFePO4, NiMH, NiCd and 1.5 V Li-ion batteries.

Thanks to the broad support of numerous Li-ion, LiFePO4, NiMH and NiCd batteries as well as 1.5 V Li-ion batteries, the Vapcell SU2 is a versatile charger for many common battery formats. This makes it suitable for torch, electronics, measuring device and modelling batteries as well as for many other everyday applications.

Highlights of the Vapcell SU2:

• 2 independent charging bays for simultaneous charging of different batteries.
• Maximum charging current up to 1×5A + 1×1A or 2×3A for Li-Ion and LiFePO4.
• Versatile universal charger for Li-Ion, LiFePO4, Ni-MH, Ni-Cd and 1.5V Li-Ion batteries.
• Wide format compatibility from compact round cells to larger formats such as 26800 and 32700.
• Simple Mode and Pro Mode for particularly easy operation or advanced manual settings.
• Auto Mode and Manual Mode for automatic current allocation or specific manual selection of the charging current.
• Wide charging current range from 50mA to 5000mA depending on battery type and operating mode.
• Automatic current distribution in Auto mode based on the measured internal resistance.
• Large LCD display with real-time display of battery type, voltage, current, capacity, internal resistance, energy and charging time.
• Adjustable charging current for customised and controlled charging of different cell types.
• Automatic battery detection for convenient charging of many common batteries in simple mode.
• Support for 1.5V Li-Ion batteries with customised charging characteristics.
• USB output with power bank function for supplying external devices.
• Contact design also for difficult cell shapes such as slightly recessed positive terminals, button-top and many protected cells.
• Safety functions such as reverse polarity protection, activation of low-voltage cells and detection of faulty batteries.
• Suitable for many applications such as torches, electronics, measuring devices, modelling and other battery-powered devices.

Important note: For small Li-ion batteries such as 10440 or 14500, Pro mode should preferably be used in conjunction with Manual mode and reduced charging current. For unknown or very small cells, the charging current should always be selected based on the data sheet. A detailed table of the charging currents can be found under “Technical data” or as a download inPDF format.

Supported battery types:

Technical Data

The following values are intended as a practical guide for everyday use. The data sheet for the respective cell is always authoritative. The lower charging current should always be selected for unknown batteries.

Important note: Particularly small Li-Ion batteries such as 10440, 14500, 16340 or 18350 should be charged with a reduced charging current if possible. For chargers with manually selectable current, a low setting is generally recommended for these formats.
