Sea Scout – What battery pack?

[Simon FrostParticipant @simonfrost57886]

I am new to model boats and have nearly finished building a Sea Scout kit from the Vintage Model Boat Co. She will be powered by a 545 brushed motor probably with an Electronize ESC.

My question is, what battery pack should I consider using? Can anyone share their experiences with this particular model?

Many thanks for your help

Simon.

NiCad pack of voltage to suit the motor. Capacity, generally, as much as you pocket will allow, based on C" size cells.

Hi Simon For that type of motor I would be looking at 8.4v NiMh With as large a capacity as can be fitted comfortably. (4000 or 5000 mAh)

As Malcolm Says; as large capacity as you can justify and afford I tend to use bigger battery and less balast, it gives longer sailing times.

I am building a similar model (sea nymph) what sort of run time can I expect from a single charge (of say an 4000mah battery) I am just looking for a ball park figure

Sea Nymph is only 18" long and powered by a standard 385 motor with a 30mm 3-blade prop (if you use the recommended one). On 4000mAH I reckon you'll get 3-4 hours running at full speed. Just pottering about with a few full-speed bursts there will be enough capacity to send you to sleep!

Phil Using a 545 motor set up for best efficiency the motor would take about 6A flat out (the value for current is that quoted in sales literature ).

From 4000mAh ie 4ah this would give about 60 x 4 /6 ie about 40minutes max.

Realistically half a hour would be a good estimate.

If the model was set up for more performance then the time would be considerably less

Thanks for the info. I think 30 – 40 mins is more than enough for me
