i NOTICED THE voltage difference after a run.
2.82 4.20 after balancing
I would solder on new balace plug and re shink wrap the pack. But if they are Maxamp make them stand behind it and replace it. I won't touch maxamp stuff with a ten foot pole. By all accounts and my own experance they are worse than the $12 rhino packs from hong kong.
Hobby King is the best place to get good, cheap lipos. They sell Rhino, Turnigy and Zippy, which I suspect are all the same batteries with different stickers on the shrink-wrap. They're unbelievably cheap, especially when compared to "boutique" vendors like maxamps. I have four batteries from them, and they've all performed perfectly. Shipping is expensive, but when the batteries are literally 1/4 the price of US vendors, it's still a good deal. Try finding a 2s 5000mAh hardcase anywhere else for $23. I dare you.I would have disputed this comment before you became a NL Chapter president, but now i may just sell my maxamp packs and buy some of these rhino's, can you give me a link?
Have you verified the individual cell voltages at the balance plug with a different meter? If you're just going by what the charger says, it might be wrong. If one meter is saying the the total is 8.2, and the monitor is giving you individual readings that don't add up to that, then one of them is wrong. I'd check it with another meter and make sure. For preference, a standard multimeter would be best so you know it's the same circuit measuring each cell.

lol that was a joke ... put those cells behind a 150-200 amp system and its all different story's with the same end result.Hobby King is the best place to get good, cheap lipos.

You need to call castle and let them tell you ... I wont try and educate you on sine waves and all the other things that effect the ESC in 8th scale systems. I have made that call. Do it, its worth your time... If they are properly rated any pack will be fine. The issue with the sub par brands is they are rated at 30 C yet put out 22-25 and void your warranty on the castle system with HPI. I think its 26C or so might be 24 that is the cut off , not sure but any pack less then that WILL smoke the MMM. Only reason I use the Hyperion packs Is I run 5S I need my pack ratings to be exact on the 2S and 3S. The other company's can't give this to you. Ill gladly pay. On my 10th scale stuff Ill run anything and do ..No battery pack will ever cause your ESC to catch fire, no matter how bad it is. Bad packs can give poor performance or destroy themselves, but they can't hurt the ESC unless they actually explode and physically damage it that way. If your ESC melts down, it is because it is overworked, shorted on the output side (the wiring or inside the motor itself), or was defective from the factory. You can't blame a blown ESC on the batteries.
And honestly, I've never seen any legitimate testing done that shows the HK batteries to be all that much different than the premium brands. The only thing close to a scientific test I've seen was the big squid LiPo shootout, which puts zippy smack in the middle of the pack. And honestly, the packs that beat it didn't beat it by much in any of the categories. The number one pack (hyperion) was a whopping 2mph faster and actually had a lower measured capacity - all for more than 3x the price.
I know that RC is a competitive thing, and that it's worth it to a lot of people to pay 3-5x more for a battery that is maybe 5% better. It's your money and your truck, so if that's how you want to run, then awesome. But it is a mistake to automatically assume that a cheap pack is "vastly inferior" to an expensive one, because what little verifiable data exists (and my own experience with them) says they're damn near as good.
Thanks
I'm not sure how to measure the individual cells threw the balance lead.
I am testing the total voltage threw the deans and that matches the charger readings
so I tried to check the cells individually threw the balance leads but that didnt work
one reads 4.2 and one reads 8.4 so thats not going to work.
I did go ahead and replace balance lead and plug.........Its fixed!!!!!!
Thanks to all that helped~
