HK "B" Grade LiPo's

[Diesel6401]

Looks like HK got some super cheap lipos in, "B" Grade , so my question is who's going to be the test sucker - I mean subject ?!?

[Basstronics]

How cheap are they compared to there "A" grade?

[ron1950]

not me said the guy that just threw away a hk grade A battery that was prob 3 months old and had a cell that would not charge

I don't know, I was checking them out last night as I was ordering a few packs from HK anyways, seems kinda sketchy. The $$ wasn't bad on some, but I still couldn't bring myself to order them.

I would try one MAYBE as a rx pack, but I have 0 intention on using them as my main power source.

i wouldnt even bother, unless youre really on a budget. whats a 2s pack like 25 bux? is that not super cheap?

IMHO... That is the last place I would try one of these packs. How much are your boats worth to you?

I can tell you this, they are worth alot less when they are beached on a load of rocks.

This is just my opinion though, and I am all about a good value.

I'd only use them in my scale boats where the amp draw is only between 15-40A, depending on the boat. But that's where my used & tired packs from the fast boats get retired to. So I guess I won't need any at all. But I think they are more suited to very low amp draw setups.

The last batch of "A" grade turnigy's I bought are crap! Dead or low cells on arrival. Puff on first 1C charge, and one ignited on the bench!

NO MORE CHEAPASS BATTERIES FOR ME.

I think Turnigy are taking advantage of their own popularity now & don't care about quality control anymore because they know that people won't bother sending them back. Happened to a guy at our club. A dead cell on arrival. He just gave it to me & I converted it from a 4s to a 3s pack. Another pack for my scale boats.

I agree with that statement and value your opinion, and I doubt I will ever buy these, I still use nimh rx packs, but reason I stated that that if i did get them i would use them on my rx is my ds3x gives me a voltage reading of my rx pack and all my fail safes are set, so if I lose signal or battery power to the rx boat just stops dead in the water (servo and esc to neutral.)

*I do not plan on ever buying these packs though ANYTIME. I posted this thread for conversation and alert on new products.

i wouldnt risk these they are telling you right in the description that these are high resistance
unstable batteries for your not so important applications, no matter what the application WHEN IS SAFETY NOT IMPORTANT just my 2

I was reading the subject when i ran across what Paul 785 said about a friends gift of a 4s and he made it a 3s

I was reading the subject when i ran across what Paul 785 said about a friends gift of a 4s and he made it a 3s.------****** Where can i find out info on how to change -say a 3s to 2s when 1 cell goes bonkers. If there's an article, i sure would like to get that info. Thanks.

seems how i'm taking a 2s cell and a 4s cell that each have a dead cell an making a single 4s i'll include some picks of that.

I made a couple videos for you, hope it helps
