I've been reading more about the 787 batts. This might have been mentioned prior but the article said these are lithium cobalt's and not the traditional LiPos. The article went on that these are more violent or unpredictable. Anyone have more?

I would disagree. I bought a Fun Cub last year that was plagued with the a vibration which shook the fuse apart. Many others encountered the same problem. Someone started building and selling a lite ply motor mount solution to overcome this design flaw.

So much for "design flaw". More like "end user error".

My Cub has a 480 and runs on 1300s on up. In fairness many over power theirs and get spectacular perfomance. The do have to beef up the nose as it vibrates something fierce. When I took out the Power 15 and reoves the 4 fishing weights in the nose I now have a high wing beauty that flies inverted with a little flap.

These same people have to do major LG mods to keep the prop from breaking when they land. To each his own.

Almost all of our RC batteries are LiCo or lithium cobalt chemistry. This chemistry is the most "unstable" as compared to the LiMn and LiFe chemistry packs.
For instance, the Thunder Power packs.

I'm new to RC and all of this talk about storage/charging/discharging/balancing lipo batteries has me wanting to ditch it all-together...

I just want to fly my RC plane without burning down my house!

Welcome to the sport. Just fly man. It will all be good. Primary rules, don't charge/store unattended and store in a fire safe or ammo can outside or in garage. The rest you will work out and learn for yourself.

For what it's worth.
Mine occurred with the stock motor.

Just do a little reading on the care and feeding of lipos and be sensible. Take care when charging. Beware of any packs after a crash, store them in a safe fire resistant way and you will be fine. Jim

Hellow,

I do not read all those page (but most off them).
What about if You can not charge them in garage or outside house ?
I can only charge the Lipos in my badroom , putted in safe bag from HK.
Anyway..i think that if they get fire, even puted on the bags, the room will not be a nice place where to stay a while.
Once at some month, i prefer to trow away the old Lipos and get new one instead.
I hope that never happend to me.

I almost forget the most important part.
I travel allot with the campervan, and in the summer..I even live on it for long time, so I keep the Lipos with me.
I can not have bags for eacch lippo, and keep more batt in one bag.
Anyone have better solution for this ?
It's not big camper, but only campervan, and the space is limited ..non mention safe space that is inexistent.
When I drive, most of the time , the lipo bags are on the bed, when i go to sleep, I put the bags on front driver seat.
In case of fire, I do not see verry well the situation. What else I can do ?
Don't tell me to leave home the lipos

Here is some more info about LiPo's, charging, using etc. that might be helpful. Also, there is a picture of a LiPo on fire from charging incorrectly.

Get a vented ammo can covered to keep water out and store outside?

Have to keep them from extreme temps though.

I just puffied two eflight 1800 lipos other day. Fairly new batts. I neglected my 1C rule and tried 5C as I thought I may have been being too conservative. Listening to others pumping mega watts into theirs I guess. O well. Expensive leason.

This will not be easy, because the van stay loot in sun, and the ammo can will be verry hot.
But anyway ..I like the idea and I will search some cheap ammo can, even if I have to keep that inside the van, it's still better then only fire bag.
What about if I have a hole in front of the of the passenger legs, under documents box , and I manage to mount some ammo can with a tube that go outside the van for ventilate the can ?
In case of fire, to direct all the smoke outside the van, so I will be more safe inside when I sleep.
I supposed that even if the can is not ventilated from default, with that tube will be the same think (or not ) ?
Can be this a solution, anyone try something similar before ?

This sounds plausible, but test it with a CO2 cartridge or something. (Carefully.)

A general point that people often fail to mention: Don't store fully charged if you are worried. A partially charged battery has less energy in it. Admittedly, it's a pain in the neck to have to charge shortly before flight, so YMMV.
