Thanks, Rodney. I’ll check that out. Maybe the EPropulsion is a little less pricey than the Torqueedo.

If you could somehow get it overboard; that, would be good for the boat, but bad for the environment. Because of the huge amount of stored energy and reactivity of lithium/water, I don’t think any commercially available fire extinguisher would work on that type of fire. That’s my whole point. Although it’s a low probability event, if your lithium battery starts burning, it might be a lose the boat situation. There’s no good way to put something like that out and it’s bolted down so you can’t get rid of it.

Is there a better recommendation than abandoning ship and watching the boat and the battery sink? Is there a good device to extinguish a Li battery fire? All I carry is a 10lb ABC extinguisher.

Batteries must be securely mounted so they can’t tip over, preferably low and near the center of the boat. If lead/acid batteries get dunked in sea water, the sulfuric acid electrolyte and lead sulfide on the plates will react with the sodium chloride in sea water to produce chlorine gas, which is quite toxic. If lead acid batteries are overcharged, they can release hydrogen sulfide gas, which is very smelly and also toxic. More modern nickel/lithium batteries use lithium. Lithium is a reactive alkali metal and reacts with water to produce hydrogen gas, which is quite flammable. Note, if your lithium battery pack is on fire, do NOT try to extinguish the fire with water! You will only make things worse. Modern marine batteries are usually sealed against water intrusion; but, especially with big battery packs, you need to be aware of what hazards you are carrying. It’s another big energy source that needs to be properly handled and respected.
