I am impressed with my 12 volt DeWalt drill, run time and power is great. Considering using in my RC sub, maybe in the wet side, Any opinions?

There are circuit boards internal to those batteries. You shouldn't get them wet unless you waterproof them somehow. https://youtu.be/8eDtZX6isbI?si=BkzVN2BgJ-LXqsT2&t=377

A dive scooter manufacturer currently employs these batteries in a dry-sealed application. My older model uses a legacy proprietary battery pack, and converting to tool batteries would provide greater flexibility and ease of replacement. https://dive-xtras.com/pages/cuda-x-seriesNow if you'll excuse me, I'm going to go on an overnight drunk, and in 10 days I'm going to set out to find the shark that ate my friend and destroy it. Anyone who wants to tag along is more than welcome.Comment

Just lithium cells in a pack. Look for 18650 and 21700 cells.Comment

What are the amp hours of that battery? AMPH?Comment

12V @2AH, I get hours of heavy use like installing self taping wood screws. I am impressed at how long it last.Comment

Got one, using it on my workbench for 12VDC power supply. Works great, don't think I will put it in a boat. PS - it comes with a fuse, very handy, had a speed controller with a short, no damage.Comment

Water can cause corrosion and damage to the internal components of the battery. My opinion? Stop asking ridiculous questions about running batteries in wet, especially batteries that weren’t meant to be wet, period. Do you really think that a drill battery was meant to run in water? There are plenty of batteries out there that will fulfill your needs, in dry conditions. The battery pack itself is a potential hazard. If submerged in water, it can short-circuit, overheat, and even explode. And I don’t give a damn what kind of experiments have been run with batteries and water, you’re always risking yourself and your boat by doing it. Just imagine you submerge your battery and water, run it for a certain amount of time, bring it out, open it up and it blows up in your face, hurting you and someone else. You really want to take that risk? If so, get yourself some extra insurance. Lastly, DeWalt drills typically use lithium-ion batteries. Screw with those, and you’re gonna get hurt.

It seems if you try to correct a post more than once for spelling, or whatever reason, it gets flagged. This has really gotten old.Of the approximately 40,000 men who served on U-boats in WWII, it is estimated that around 28,000 to 30,000 lost their lives.Comment

That's nto a ridiculous question. It's 100% valid and pertinent to our hobby. Ask away, Ed. Casey seems to have a severe case of the kermudgeons he needs to work through before he gets his ass in trouble.
I fully agree that the potential exists, but it would have to be exceptional circumstances. I've been running SLAs, NiMh, NiCd, LiPo and LiFe in the wet for decades and not one has exploded. Prep them properly. Treat them well, and running them in the wet is perfectly valid.
You miss your morning coffee or evening nightcap, Casey? You got a serious case of the grumps. And no one likes a grump.
