Hello all.
Have a concern, Today while getting ready to fly I notice one of my power 4 batterys to my Typhoon H was puffy on the sides, wondering if anyone knows why and is it a problem. Please let me know.
Wow! ...Your Electrolyte has started breaking down causing excess oxygen, thus the swelling, this excess oxygen fuels fire and explosions, DO NOT USE!
I am sling the Battery ...As BoomBoom says. Sling it.
A swollen battery can be very unpredictable. Some people carry on using them and sometimes they continue just fine. But this is a gamble: Since they are unpredictable, they can drain suddenly causing your aircraft to drop from the sky...this happens without any warning (apart from the swelling already observed), and at worst they can catch fire. A new battery, or a new house...your choice.

I do ....Would love to see images of your puffy battery, if you still have it.
I would never have just thrown in trash ..Do not simply throw it out... to safely dispose of it, you need to drain the battery voltage to 0.0 Volts. To do this, just put the battery in a small bucket of salt water... 1 cup salt to 1 gallon of water. Leave submerged for about 3 days... take out and rinse off corrosion at the terminals of the battery, pat dry, and check with a volt meter. If not at 0.0 V put back in bucket for another day. Once at 0.0 V, you can simply throw out in the trash.
You can just make out the swollen inlay ...
Hey jeff.Whew! Top (and assuming bottom) showing some deformation, not the hard plastic sides.
Several months ago, a similar conversation was taking place. The level of swell a bit more than this. I have a couple “great performing” batteries in similar condition. Seems more like the label plates have expanded and contracted due to heating and cooling, for mine anyway.
Curious how your flight times were for this battery?
Not saying anything contrary, whatsoever, to your decision to discard.
Jeff
Hey jeff.
This battery has never been used. Has never been in my craft,
I have two other batterys and my flight times are usually less than 20 mins at a time so this battery was a back up battery ... And yes on the top and bottom are both puffy and the feel is like there is air or gas behind covers ...
I would rather be safe than sorry.
Its all good ...Definitely your call.
More reading on the topic, including some additional “expert” opinion. (Quotes are acknowledgement, not mocking!)
Level of puff
Eagle is, of course, correct. When I said 'sling it' I should have been more specific on the actions one should take in slinging it. Fully discharge the battery is the neighborly thing to do. Also, avoid putting it into the normal garbage if you can. My local waste/recycling plant has a bay for discarding batteries...usually for car batteries, but a discharged lipo would be good to go in it.Do not simply throw it out... to safely dispose of it, you need to drain the battery voltage to 0.0 Volts.

I would get a real charger instead of the factory thing that tells you nothing. Get the new 7100mah Venom. Great battery life and a warranty.Would love to see images of your puffy battery, if you still have it.
