The FBM B3100 spare battery provides extended operational run-time for users who rely on the CombiFlux FP 314 system. In dynamic fluid handling environments, where frequent container changes, long shifts, or high-volume dispensing is routine, having a fully charged spare battery consequently allows for rapid replacement, without interrupting workflow.

The battery utilises Lithium-Ion chemistry, thereby delivering high energy density with low self-discharge. It incorporates protective circuits at individual cell level, consequently preventing thermal overload and ensuring consistent long-term performance. Furthermore, by reducing reliance on mains power and providing cordless operation, the FBM B3100 battery enables mobile pumping in remote or confined areas, where traditional electric pumps are impractical.

What are the benefits of a spare charger for the FBM B3100 battery motor?

Having two charging stations in different locations can be useful, for example, if the CombiFlux battery pump is carried onboard a vehicle, or used on several different sites. In addition, should the battery run out at a critical moment, having the possibility to recharge locally could save a lot of time.

Using our CE and UKCA compliant charger guarantees compatibility with the battery’s built-in electronics, thereby facilitating precise charging cycles that maximise battery lifespan and operational safety. It prevents problems such as overcharging, thermal stress and polarity mismatch – issues that can occur with universal, or incompatible chargers.

The charger’s internal microcontroller regulates voltage and current output dynamically, consequently adapting to changing ambient conditions and battery status. Furthermore, its ability to complete a full charge in just 30 minutes supports heavy-duty operation in critical pumping applications. Moreover, the LED display gives operators clear indication of charging status.

Spare batteries can be instantly replaced for uninterrupted operation, therefore reducing downtime

The rapid 30-minute charging cycle reduces operational delays

Advanced protection against overcurrent, short circuit, deep cell discharge and overheating, thanks to built-in safety systems

Designed for use in challenging conditions, with wide operating and storage temperature ranges

Automatic sleep mode and low self-discharge increase battery longevity

Ergonomic size makes handling and storage simple

Engineered specifically for the FBM-B 3100 motor and CombiFlux FP 314 pump

The FBM-B 3100 brushless motor is a core component of the Flux CombiFlux FP 314 pump — a versatile, seal-less pump solution, suited to transferring low-viscosity fluids from drums, IBCs and smaller containers. The modular design allows users to switch the motor between multiple pump tubes, eliminating the risk of cross-contamination. Therefore, cleaning costs are reduced, while adding liquid handling ability.
