RE: [Electric Boats] Feasible to change to 6v golf cart batteries?

 

Hi

 

Charging lead acid batteries give off hydrogen at ANY stage of their lives. Which is why they always need to be well ventilated, terminals tight and covered, and away from any source of ignition.

Batteries in parallel get dangerous at the end of their life.   So yes you can go out and have a good time for years, but then one day your batteries start gassing off hydrogen gas.    They can gas off when charging or when discharging and yes they can blow up.   It can be quite disconcerting to see your battery in pieces and acid all over the place.    Might even wreck your mood that day.

Be careful, and monitor batteries for balance more near the end of their battery life, and replace the entire pack when the voltage gets spongy.   If there is any abnormal warmth in the battery at all, or any anomaly in the performance, its time for a new pack.   

this applies to all lead acid battery packs.

Safety First Always.   We don't want carelessness to ruin years of good fun with electric boating.
