Various practical situations show that the Jet Thruster displays optimal performance using an Optima YellowTop battery.

Using an OPTIMA® battery under a heavy electrical load offers two important advantages. On the one hand you have a higher voltage at your disposal, granting you higher starting power than with traditional batteries. On the other hand the battery offers the deep-cycle possibility. The OPTIMA® YellowTop is a dual power battery (starter and deep-cycle), and possesses the unique ability to be repeatedly discharged at a low voltage, only to be charged again.

The preferred placement of the Optima YellowTop battery/batteries is directly beside the Jet Thruster’s pump unit. You can then connect it with short cables, or have someone do this for you. This will result in the Jet Thruster performing optimally with the smallest possible electrical losses.

– An Optima YellowTop battery placed directly beside the pump unit guarantees a minimal voltage loss between the batteries and the Jet Thruster’s DC motor.

– In this installation lighter cables can be used, and they can be fitted more easily.

– The relatively light, compact and impermeable Optima YellowTop is even easily installed in small spaces.

– An Optima YellowTop battery has a very high cold start capacity. This high capacity ensures the Jet Thruster’s optimal performance.

In addition to a correctly executed installation of the Jet Thruster system, the available electrical capacity is important for getting the best possible output.
