ProTek lipos
 

Hi,

I found this http://www.amainhobbies.com/product_...ducts_id/16870 browsing amainhobbies.

5S 4000Mah 20C 2C charge rate for $130, seems excellent? To good to be true?
Anyone tried these?

Too bad I have a MM esc, there doesnt seem to be any 4S packs :(

Without having run this pack, I can't comment on it. But in the description it says it comes with 16awg. wire, which is way too small for a pack that's rated at 80amps continuous.

Deal looks good, but MetalMan is correct... .. but that's a good price if the specs where true... Maybe it's 20C continuos discharge for 15 Seconds... LOL
the max discharge rate of 30C is only for 3 seconds.. :lol:

I would bet theyre wrong about the 16ga, in the pictures it looks more like 12ga wire. If I were in the market for more lipos I would probably give those a try.

Håkan Johansson: Hi?

Dan: How may I help you today?

Håkan Johansson: I was just wondering if the wire type on these lipos where correct it says (16 GA Wire), http://www.amainhobbies.com/product_...ducts_id/16870

Håkan Johansson: it seems too thin for 80A cont.

Dan: Give me just a moment to check on that for you.

Håkan Johansson: Thank you!

Dan: that is how those batteries come to us. We have flight tested them and they work great, we have had no issues. You can always solder thicker wires on if you feel you need to.

Håkan Johansson: ok, could you also get them in 4S?

Dan: we do not have them in 4S all we have in that size is the Thunder Power batteries.

Håkan Johansson: ok thanks for your help!

Did you spot these? You'll need two for 4s, but it has the same discharge ratings as the 5s pack- same cells I guess.

Okay, so what he is saying is that they used about the thinnest wires on them they could find.. :)

Cool feature though, that live chat..

Yeah I was kind of surprised that it worked actually :)
Im in Sweden and didnt check what time difference it was so I guess I got lucky :)

If I have 2 2S packs can I charge them as one pack somehow?

Yeah, you could.

But i isn't it an option to buy two 4S packs from truerc.com?

But the ProTek lipos has 2C charge rate which would be a really nice feature!
I always charge my TrueRc lipos through a balancer, could you do that with two 2S packs? Could I just solder them togheter to one balancer contact?

No, you need to charge them in series and treat them like a 4S pack with balancing.

But how do I physicly connect them to the balancer? There will be two connectors from two packs?

well, you need to make a special charge harnass for them;

you need a total of 5 wires on the ballance cable.

Yeah ok I see what you mean, I was thinking of 2 4S packs in parallell.

so has anyone tried these yet
