opinions about batteries....

THat's interesting, it seems like old school lipo's are made with a more stable chemistry as far as calender life is concerned if what you guys are saying is true.

Anyone else have some old (6+ years) packs that are still perform strong? Post it here.

BTW, a good pack these days will hold a 20C discharge at ~3.7v/cell (at mid discharge) or how about 3.5V @40C discharge.

Hmm... quite funny I was thinking that my older LiPo's were better than my newer packs somehow. In 2008 I think I bought some Rhino's (at that time they were the high-quality packs at Hobbyking. Is it still like that now?), 1350mAh rated for 30C continious (= about 40A). They've seen lots of 80A+ spikes and the cells reached 2.7V per cell. Now, 4 years later, they're doing nothing in my hobby room with no single cell puffed. And as far as I remember, they always performed awesome during I was abusing them.

I'm very careful with my newer Turnigy packs as I'm afraid one of them will start to burn out of nothing and take out my house as well. So I always put them in a LiPo bag in the garage on a stone floor. But those old and abused Rhino packs lie in my house, without LiPo bag, on a wooden table and I'm very confident nothing will happen with them. It might sound very funny but I'm so scared of my new LiPo's...

I leave my neu batterys that are years old and probably more at risk of burning up laying around charged or nearly discharged and not worry about them but this zippy lipo I bought, I can't go to sleep unless im sure that souless SOB is tucked into a lipo sack near the fire extinguisher. Wish I was kidding

haha, put it in a battery recycling bin then.

I recommend quality over cheap batteries that won't last as long. MaxAmps.com is a great option:

HAHAHHAHHAHA
Pay extortionist prices for a chinese celled pack assembled in a garage by a bunch of smug guys that throw a flame decal on it and call it the "best"..No thanks.

The word maxamps is "taboo" around here. Bring it up and the bashing begins.

Hey Mods- let's ban Brandon Wilcox. It will be easier than monitoring every thread he comments in- we are going to bash him relentlessly.

[jayjay283]

omg no he didn't.

Mods can't ban, only Mike can do that. Personally, I think we should since Brandon hardly ever (if at all) has any input except to peddle his product, but again, it's up to Mike.

Unfortunately, I once was a sucker for MA and regretted it.

I dropped nearly a grand on several packs years ago and they all puffed within weeks in very conservative set ups. I called customer service and was told I was SOL with zero explanation. I know things have changed slightly for their returns since then but I'm still out huge hunk of cheese.
No mercy from me

Luckily I only made that mistake once! It still amazes me how popular they are due to the publicity they get....little to do consumers know they are in for trouble
