I had a question for all of you who are running battry powered pumps to bail your dories. What kind of housing do you use for the battery. I have seen the housings on jamestown but they would appear to be weather-proof or splash-proof cartainly not water-proof. is water-proofing needed.  What type of battery do you use that can withstand a flip while reatining the neccesary water. I have heard that batteries generate gas while charging is this true of when they are being used. If anyone has comment or photos of what they have done it would be appreciated. Thanks Jake

Several of us have been using steel ammo boxes.  I have attached some photos.

 

WARNING!!!

 

A 100 AMP hours lead acid battery has enough power to melt steel.  Double and triple check that the parts you make to isolate the terminals from the steel of the box can not fail.  If you use a piece of rubber that sits on top of the battary, be certain it can't move.

 

Good luck and be very carefull.

We use an AGM battery which can take a fair amount of movement without damaging the battery.  They can be installed in just about any position, ours is on it's side in wood box.  There is a one way pressure relief valve in the battery but no fluid should leak  They cost more but last longer. The battery we use is made by Lifeline Batteries, I believe they sell nationwide.  Todd Wells, an electric boat enthusiast, has a good book online that discusses batteries and battery care.  His battery interest is for propulsion use but the info is still valuable for any kind of boat battery bank. http://electricoutboardhandbook.com/

David,

 

The 43 page pdf file on battery and electric motor information at this site is great information.  This is the first I have seen of this web site.  Thanks for posting the link.
