I'm making a project/rc boat to map the bottom of a lake and therefore I need a relatively big battery (say 12V 10Ah) for the operation and electronics of the small boat (propeller motor + telecoms + servo rudder control + GPS + depth sensor + micro-controllers etc).
To make the boat more stable I would like to make the heavy batteries submerged in a sealed container along with the depth sensor.
From all the batteries I've searched LiFePO4 seems like the most viable choice.
Is this a wise choice for this particular application?
I recall everyone that the sealed container can be made in metal (no problems with weight/mass) hence it would always act as a heat dissipation for the batteries therefore reducing possible damage due to high temps.
Is there something that I'm missing about this type of batteries that would not make then suitable for such an application? The boat/rover would have on top a solar panel to recharge at least a bit the boat making it way more autonomous in the lake and hence avoiding annoying recharging of the battery on shore. So the battery would operate sealed and recharging while submerged. Thanks in advance for your comments.
