ViFly 1S Series Charging Board

The VIFLY 1S Series Charging Board allows you to charge up to six 1S whoop batteries simultaneously using your standard hobby LiPo charger. Unlike traditional parallel boards, this board wires your 1S packs in series, effectively combining them into a single 2S to 6S battery. This allows your primary smart charger to monitor and balance each cell individually, which maximises battery lifespan and entirely eliminates the voltage-equalisation risks of parallel charging.

Key features

• Integrated rotary switch allows you to easily select the exact number of connected batteries (from 1 to 6) without requiring dummy plugs or shorting wires.
• Features dual ports per channel, supporting both standard PH2.0 and BetaFPV BT2.0 battery connectors.
• Series charging architecture ensures precise individual cell balancing from a standard hobby charger.
• Connects to your charger via a standard XT60 main power lead and a 6S balance cable.

Note: When charging in series, only plug in batteries of the same capacity and chemistry. Never mix PH2.0 and BT2.0 connectors on the same channel simultaneously, and always ensure the rotary dial matches the exact number of plugged-in batteries before initiating the charge.
