VIFLY ToothStor 4-Port 2S Charger - BT3.0 & JST-XH2.54

Description

The device VIFLY ToothStor 2S supports 2S LiPo and LiHV batteries and can operate with up to four battery packs simultaneously. Four independent channels allow batteries with different voltages and capacities to be handled without matching their state of charge before connection. This version provides BT3.0 and JST-XH2.54 3-pin connectors, while batteries are connected through their balance leads without requiring the main battery power lead.

Each channel provides a charging current of up to 1.5A, a discharge current of up to 0.2A and a balance current of 0.2A. ToothStor supports target voltages of 3.80V, 3.85V, 4.20V or 4.35V per cell. The 3.80V and 3.85V settings are intended for preparing compatible batteries for storage, while 4.20V and 4.35V correspond to full-charge voltages for LiPo and LiHV batteries respectively. After selecting the target voltage, the charger automatically charges or discharges the battery depending on its current voltage.

The color LCD provides information about the operating status of the individual channels. The memory function retains the previously used settings, while the integrated buzzer indicates the end of a charging cycle and can be disabled. A fan and heat sink provide heat dissipation during operation, particularly when discharging batteries.

Input power can be supplied through USB-C PD3.0, XT60 or a DC 5.5 × 2.1mm connector. The input voltage range is 10-26V and the minimum required input power is 65W. The enclosure measures 109 × 56 × 30mm and weighs 142g. The charger can be used with 2S battery packs in RC and FPV applications.
