The Vapcell BL4 is a powerful universal charger for a wide range of modern battery types and has been specially developed for users who want to reliably charge, analyse and maintain their batteries. With four independently operating charging bays, precise charge monitoring and extensive test functions, the charger is suitable for everyday use as well as for demanding applications in the hobby or technology sector.

Extended analysis, test and maintenance functions for lithium and NiMH batteries

In addition to the classic charging process, the Vapcell BL4 offers additional functions such as capacity tests, discharge programmes, a storage mode for the optimal storage of lithium batteries and a repair mode for the possible reactivation of deeply discharged cells. This means that the condition of rechargeable batteries can not only be checked, but also optimised in a targeted manner. (1.5V Li-Ion: charging function only, no analysis functions)

LCD display with real-time display of voltage, charging current, capacity and internal resistance

The integrated LCD display shows all important charging parameters in real time during operation. These include voltage, charging current, capacity, internal resistance and the charging time to date. The automatic battery recognition and the adjustable charging current enable safe and controlled charging of a wide range of cell types.

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 BL4 is a versatile charger for many common battery formats. This makes it suitable for torch, e-cigarette, electronics and modelling batteries as well as for many other everyday applications.

Highlights of the Vapcell BL4

• 4 independent charging bays for simultaneously charging and analysing different batteries.
• 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.
• 5 operating modes with Charge, Test, Storage, Discharge and Repair.
• Capacity test function for reliable determination of the actual battery capacity.
• Storage mode for gentle storage of lithium batteries at optimum storage voltage.
• Discharge mode for the targeted discharge and condition assessment of rechargeable batteries.
• Repair function for the possible activation of deeply discharged cells and for refreshing compatible batteries.
• Large LCD display with real-time display of battery type, operating mode, voltage, current, capacity, internal resistance and charging time.
• Adjustable charging current for customised and controlled charging of different cell types.
• Automatic battery recognition for convenient and safe charging of many common batteries.
• Support for 1.5V Li-Ion batteries with customised charging characteristics.
• USB-C power supply for modern and convenient power supply.
• USB output with power bank function for supplying external devices.
• Safety functions such as reverse polarity protection, overcharge protection, short-circuit protection and faulty battery detection.
• 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, the Pro mode with manually reduced charging current should preferably be used. In Simple mode, the automatically selected charging current may be too high for very small cells. A detailed table of the charging currents can be found under "Technical data"

Supported battery types

The Vapcell BL4 is designed for a wide range of modern battery types and supports both lithium and nickel-based round cells.

• Li-Ion 3.6V / 3.7V in Pro and Simple mode
• Li-Ion 4.35V in Pro mode
• LiFePO4 3.2V in Pro mode
• Ni-MH / Ni-Cd 1.2V in Pro and Simple mode
• 1.5V Li-Ion in Pro mode

The charger is compatible with formats including 10440, 14500, 16340, 16650, 17500, 18350, 18490, 18500, 18650, 20700, 21700, 22650, 25500, 26500, 26650, 32650, 26800 and 32700 as well as AA, AAA, SC, C and D.
Rechargeable batteries xx800 can only be charged without integrated protection electronics (max. 82mm).
Size 32650 can only be charged in charging slots 1 and 4, also some 26650 depending on design. Cannot be charged in charging slots 2 and 3 as the positive terminal can slip off the contacts.

Operating modes briefly explained

• Charge - For reliable charging of compatible batteries in normal charging mode.
• Test - For determining the actual battery capacity through automatic charging and discharging cycles.
• Storage - Ideal for preparing lithium batteries for gentle storage.
• Discharge - For controlled discharging and assessment of the battery condition.
• Repair - Supports the possible reactivation of deeply discharged or underperforming batteries.

Scope of delivery

Technical data of the Vapcell BL4

Recommended charging currents for common battery types

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.
