A wide range of
batteries are available for the model boat builder. Your
options range from standard disposable batteries to more
expensive but longer lasting rechargeable. The voltage used to
power a motor will determine how much speed it is capable of
producing. For model freighters 6 to 7.2 volts is normally adequate. Disposable
For small models AA or AAA size may be used, each battery
provides 1.5 volts. Large
models can use C or D batteries. These provide the same
voltage but run longer. They also add much more weight.
Disposable
batteries are easily mounted in an inexpensive holder from
Radio Shack. Rechargeable
A wide range of options are available in rechargeable
batteries. standard size rechargeable batteries can be used in
place of disposables. Though more expensive to but initially,
they are cheaper to run in the long term.
 NiCd
Battery Packs
For larger models the choice would be a 6 or 7 cell rechargeable
battery pack. These affordable batteries produce between
6 and 7.2 volts and last much longer than standard batteries.
The higher the milliamp-hour rating (mAh) on the battery the
longer it will provide power. Your
local hobby shop or Radio Shack will provide batteries ranging
from 1000 mAh to 3000 mAh, this means the 1000 mAh battery has
only 1/3 of the capacity of the 3000mAh battery. The R/C model
"Great Laker" is powered by two Radio Shack 7.2 volt
3000 mAh batteries. This gives the model a very long
running time of about an hour. These
packs come pre-wired and plug directly into the speed control. Gell
Cell
6 volt Gell cell batteries are commonly used in
large models. They are
maintenance-free and
spill-proof, ideal for
model boats.
A 6 volt 9.6 amp hour battery powers most of the Moon Light
Modeler's fleet. He uses as large a battery as space permits.
Gell cell batteries do not like to be quickly drained and will
not last long if operated that way (with a fast drain motor
connected to them).
