So I received an email from hobbyking that they are offering new "B Grade" LiPos which seem to be incredibly cheap. Now, maybe it's just me, but these seem to look exactly like the Hobbypartz blue lipos. The specs of them are also written in the same format which makes me think they are the same.

Man, I guess at least they are being honest, but the write up on them sure doesn't give you a warm and fuzzy feeling does it?

To me those look the same as the old blue Zippy packs. I don't have the measurements handy but I'd be surprised if it's not the same pack.

No it does not. I wouldn't buy those after reading that lol. I got the same e-mail today.

I'll try to get them and compare/test them soon. What's funny is that high IR = low C. How can a pack be 40C with high IR?

That description is brutally honest lol. Their A grade stuff is cheap enough for me and they work...I would rather spend a couple extra dollars on those.

LOL that desccription really gets to the point. Some of these batteries are as cheap as the turnigy batteries

"B-Grade Lithium Polymer packs are great for those not-so-important models or testing. They have a high internal resistance (thats bad), normally wont last past 60 full high-discharge cycles and may become puffy over time."

love how they state they say hextronic sells B-grades which is what hobbypartz is billed as on credit card statements

Basically I'm guessing some of those packs are higher capacity packs which didn't meet the minimum reqs, and were down marked.
But if you charge em slower, and use them in low current draws they will preform fine

Hell I use the 3S 15C 1800mah blue lipos in my radios seeing current draw is a minimum. A $13 pack that lasts 2X longer than a set of AA's per charge in my book is a good investment even if it gets only 60-100 charges.

Yeah it seems like a bargain deal though wonder what the preformance would be when compared to a decent nimh?

IMO as long as you don't over do it they should out preform NiMh's. Lets face it they got a 5000mah 4C lipo for $15 where I'm guessing a comparable NiMh pack from other places is around $50-60 (ok I know a place that does that for $20 but they get HOT). So if you pair that up with a 1/10th scale 60A ESC it should blow away almost and NiMh for performance, and run times. It also shouldn't tax the packs too much so they should last awhile.

I don't know that it would blow it away. I don't know
