In my opinion, 2.9v/cell is too low of a cutoff point. By the time you hit that, your batteries are over-discharged. 3.4v/cell is a good setting (you don't have that option tho).

You should never run your boat til it hits cutoff. Cutoff is a last ditch effort to save your lipos. It should be based on time. Monitor your voltages the first few times you use your boat. You'll be able to get a good feel of how long it's safe to run the boat.

General rule of thumb is to not discharge your packs lower than 20% capacity. If you have a charger that tells you how much mah got pumped back into a pack after charging, you can figure out how far you went. Then go back to your times, and now you can get a good feel for how long you can run. So a 5000mah capacity pack should not be discharged below 1000mah. Your charger should pump 4000mah back into the pack.

I agree, and disagree... Sure this is a good way to extremely ensure lipos but...
I have used lvc on all my rigs ever since I been running lipos and never had an issue. Its there for a reason, not to save your lipos from extinction, but to properly tell you when to stop. There is nothing wrong with using a properly functioning lvc, IMO.

I guess that's where we'll have to disagree, lol. I say it's there as a last resort of protection. Especially when it's set at 2.9v/cell. If you have it set at 3.4v/cell, not too big a deal if you hit it. 2.9, you've gone too far.
