Description
The Fogstar Drift PRO Active Balancer (4S) is an external intelligent balancing solution created to maintain the health and efficiency of your lithium battery system. Specifically designed for use with Drift PRO 280Ah, Drift PRO 300Ah, and the Drift Seat Base, this device actively equalises the State of Charge (SOC) across all cells by transferring current from cells with higher voltage to those with lower voltage.
Unlike internal balancers that constantly draw power, the plug-in design of the JK Active Balancer allows you to use it only when needed. This means no unnecessary energy consumption and complete flexibility in managing your battery health.
Ideal for periodic use, the balancer can be plugged in every three to six months for two to three cycles, depending on your battery’s condition. Many users may find that their batteries are already well-balanced and require no intervention. This smart diagnostic approach saves time and energy, while ensuring balanced voltage across all 4S strings.
Please note: The Drift PRO Active Balancer is only compatible with Drift PRO and Drift Seat Base models. It is not suitable for standard Drift batteries.
