It's nothing outrageous. The batteries will just be a bit warm and well within any normal operating temperatures.

Son...if I've told you once I've told you a thousand times...when deep frying lipos you may ONLY USE sunflower, corn, soybean, and flaxseed oils and NEVER avocado or olive oil. The high levels of polyunsaturated fats are key to proper electrolyzation of your cathodes & anodes which increases your theoretical max amp load by 60-65%. High concentrations of oleic acid in avocado oil is for lead acid batteries only.
lol...that wasn't a break up. That was the girl apologizing for burning the pasta and promising to use use colder water next time.The Saga continues: I got a response back from Hoovo about my negative amazon review. They seem to think the batteries I received had a "slight internal short circuit" which caused the 30mOhm IR, whatever that's supposed to mean

I've never been broken up with by a Lipo manufacturer before... and here I thought the breakup was mutual....???

Yeah, it sounded like a pretty typical customer service response to an unhappy customer. I'm at least happy that there is some visibility to them about the situation and that they confirmed they saw it. Maybe they'll use it to look around and make a few adjustments? I can only assume a lipo manufacturer wants to improve so they can keep customers and keep business.lol...that wasn't a break up.

One would hope that this sort of philosophy is the dominant perspective among manufacturers in general but...thankfully the world is not powered by hope.Yeah, it sounded like a pretty typical customer service response to an unhappy customer.

LiPo seller, none of these companies that sell lipo packs actually make the cells.Yeah, it sounded like a pretty typical customer service response to an unhappy customer.

Is this a potato, potato instance? Yes they don't manufacture the cells, but manufacture or assembly of the cells into packs with wrap/hardcase, wires and leads, tab solders, etc? Still got to be done, or do they just slap a label on?LiPo seller, none of these companies that sell lipo packs actually make the cells.
I'd wager a large percentage just do the latter. Just a gut feeling though. I have the sneaking suspicion that we've probably never heard the name of most of the production/assembly linesIs this a potato, potato instance?

Also, Lipos perform at their peak potential, best when they are charged at aprox 100-110F. How the track guys do it. They like them warm. Charging at very high C rates. But they don't get much life out of them. Just want to get to the mains, what matters. Usually Stock class rigs.If you want to drive the IR lower, just pop them into a heating bag for an hour. You can cut your IR in half doing that.
I read Industry Whitepapers somewhere that IR readings are best evaluated when cells are fully charged.My ISDT does that too the ir evens out and lowers a little bit as the voltage gets closer to 4.2v.
Yeah, exactly. Stock classes are stupidly competitive because you're so limited in what you're allowed to change on the car. I'm sure all those guys have a battery sponsor too so no one cares about how fast they're burning through their packs.Also, Lipos perform at their peak potential, best when they are charged at aprox 100-110F.

And I always felt New packs perform their best after a few cycles of use.

Wow, your RC days go way back..... Like mine. Sanyo's ruled. And dam they were expensive. 1700mah NiCads were considered "high capacity" back then. 1200-1300-mah was more the norm. And yes still barely got you 5 mins into a race. If you geared wrong, you had a DNF. Which was always embarrasing at the track. Handwound Modified class designer motors were costly. $100. + Racing mod class was costly. I couldn't keep up with those guys. But I tried. My wallet wasn't that deep. I did well in Stock class. I could Place once a month. To me that was an accomplishment. I was a young guy running against older seasoned gents. But learned alot. I had 2 RC10T's, one for each class.Yeah, exactly. Stock classes are stupidly competitive because you're so limited in what you're allowed to change on the car. I'm sure all those guys have a battery sponsor too so no one cares about how fast they're burning through their packs.
Check it out man, just found these two hours ago while rummaging through some boxes. The breakfast of champions, a Sanyo 6-cell 1700mAh, a Joel "Magic"Johnson stock and Team Losi "Jr.'s Choice.

Did they not offer to replace after admitting there was a quality issue?Yeah, it sounded like a pretty typical customer service response to an unhappy customer.

They didn't, however I had already started the return process on amazon, so I wonder if their hands were tied potentially. Like "well we can't offer him a replacement if amazon is processing his return". In a way, perhaps i might have shot them in the foot, since now they can't "make right the wrong" and turn around my amazon review. But having both lipos that consistently out of the acceptable range just seemed very coincidental to me. I am not sure if I'd want a second pair to try.Did they not offer to replace after admitting there was a quality issue?
