FF Battery question (ryobi Lithium Ion?)

I use a bioenno 6 volt 10 amp lipo for my vittels bait tank. The tank has a dry box to hold the battery. The battery is heat shrink wrapped with abs. The sides are paper. I wrapped the whole battery with heavy duty clear packing tape making it more water resistant. Is this thing a ticking time bomb? It is encased in a dry box when fishing. What happens to the lipo’s if they are short circuited from water such as flooding of yak? Thanks for feedback. Ps. Thanks for reaching out on my direct message.

I don't even know why I'm wasting my time with this. This is a LIPO battery from my garage

This is a volt meter on the same 3 cell LIPO battery that I just charged. 12.5/3=4.16V


Here's a datasheet for a random LIPO cell with the charge voltage highlighted


If you somehow discovered a 4.7-5V lithium rechargeable battery, hurry up and patent it. Everyone in the battery industry knows that the electrolytes in the batteries aren't stable at that high of a voltage. What happens is that the electrolyte breaks down and starts forming CO2. Probably what happened to you guys

JR, I owe you an apology, my batteries are not charging to 4.7, instead they are charging to 4.2 volts. That being said if you are using the proper charger you cannot over charge LiPo batteries when using the balance charger. My LiIo batteries charge to 3.3 volts per cell and a two cell will show 6.7 volts when freshly charged. The houses and cars burning are not because of overcharging LiPo batteries in most cases, it is from damaged batteries from a crash or some other damage. The battery in the picture shorted to my pickup bed in transport.

Do your "LiIo" say anything about LFP(Lithium Iron Phosphate) or LTO(Lithium Titanate)on them? Easier yet, send a link of what have. I'm willing to bet they're either LFP or LTO batteries which are a sublcass of lithium ion. Which can also be packaged as a LiPo battery.
