Battery options

The Damper van sailed OK last time but only if ignored the gentle sinking going on. My feeling is that the battery pack at the front was too heavy. At the very least it was too large so I need options.

Digging through my stash of batteries, I found the ones you see. A few minutes with the scales gave me this:

4 AA's in holder- 101g

Yellow 4AA pack - 84g

Slingshot battery - 129g

Rechargeable PP3 - 42g

So it looks like 9 volts of rechargeable battery it is then. Best of all, the lump is physically smaller than the AA set in it's holder so I can move it back a bit in the boat. Let/s hope this works.
