Default Battery Mod

Hi guys,

Having just finished modding my Connecticut according to the [link=http://captainnemo12.tripod.com/sitebuildercontent/sitebuilderfiles/motorworkssubmarinemods.pdf]mod manual[/link] I thought I might share some of my ideas.

First, when diving and surfacing, the sub seemed to be stern-heavy. So after using up my 1600 mah rechargables I found that they were too heavy and encumbering at best (not to imagine what 2500 mah+ AA's would be like[&:]).

The solution? I decided to swap the heavy AA's with one of the battery packs from one of my radio systems. These packs are usually included when you buy a radio and are used to power the receiver and servos. Mine also happened to be 4.8 Volts so everything was perfect.

To begin, I used some light grit sandpaper to roughen the connector leads inside the battery compartment. Next, I soldered the male battery connector for the pack (you might have to purchase this from your LHS depending on the pack you have) being careful not to melt the plastic case. With this being done the battery pack now fits nicely inside.

The reasons for this mod?

-These packs are small, light weight and more compact than AA's,
-More current and runtime for the same voltage,
-Charger is included when you bought your radio,
-Fast charge (after 1 hour of charging my sub seemed like a fish on steroids )
-Heat-shrink wrapping also protects the cells from water to some degree.

*For added performance, you can also perform the voltage mod as mentionned in the mod manual.
**You might have to re-balance the sub after installing the new pack.

And last but not least, here are some pics:
