When using a 12v battery can you use it on its side or not

Hi Les, one thing to think about when laying down batteries, they are heavier at one end than the other, so could unbalance your hull. (guess how i found out!!!) mine capsized in the bath!!! If possible place the batteries, bow to stern, not side to side

Following up on what Jarvo said.  I have SLA batteries mounted on their sides and others flat down in my boats. The ones laying flat I found the center of gravity by placing the battery in its in-th-boat position on a small dowel on the bench top.  Roll the battery back and forth until it balances and mark that spot.  I use blue tape with a pen mark.


And GDSOB to these tiny file size limits.

But my back is fussy about that much weight.   :-)


Bet you can run all day on one charge?

Hi Les lots of good advice there. I am at an earlier stage than you and just about to select my battery. Did you go for a single or maybe two? What did you select Ah wise in the end? In my case I think two might be better as I can probably juggle them around better in the hull once the decks are in place but cannot decide on the appropriate current rating. What did you end up doing? Thanks. Derek

Hi Del Boy
I you use Lipo's you get more power and a number of sizes.
The Hobbyking Turnigy and Compact Zippy from 75 x 33 x 19 to 158 x 45 x 40mm.

Hi all, I watched a documentary about advanced batteries and the last piece was about a guy who had made a water based electrolyte.  It was shown with the battery powering some lights and the battery was being stabbed all the way through repeatedly with a screwdriver at least 10 times with the lights still on etc.  He said it just can't catch fire.
Hope we shall see some of these batteries developed for our use.
regards Roy
