Hobby King 20C Lipo packs with protection (testing water)

[RallySTX]

I don't need no stinkin, "Born on," date. I just want lipo, lots of lipo. So you're askin about $60. Per cell. That would be reasonable to ensure, tested good, packs, from a U.S. member. Just means a longer wait for me cash wise.

i'm still in for purchasing some.

Matthew has just finished building a pack for a customer.
I think I heard him talking about ordering 50 packs once that transaction is done.

Methods I'm looking for someone with a spot welder to make some packs for me, if you know someone that handles really well A123 cells let me know. I'd also like to purchase some lipo from you at a given time for some of my projects..

[BATFINK]

hello Methods,
great idea. I'm using Ping battery just now but need to get into Lipo for the lighter weight and improved performance but a bit apprehensive at building my own pack, it would be great to have a custom pack built. Just now i have 48 volt 20ah Ping with a Mac 8t kit, what sort of pack could you make to be the same as this with regards to performance, would it be possible to send a battery box and have you fill it with batteries and send it back? I would also be happy with a pack and just find a box to work around it. Is Lipo giving you more power and lighter weight for the same amps in Lifepo4? i.e. a 48 volt 20 amp lipo pack versus a 48volt 20 amp lifepo4 pack? Also what sort of price would this be?

[BATFINK]

Also im in the UK

[methods]

Sorry - international shipping will not be possible due to the retarded lithium shipping laws.
I suggest contacting http://www.jozztek.com/shop/
Jozzer can definitely build a bad ass pack.

looks like a good site, thanks, il hit him up with a message

[stoney]

Lets say he was in the US. Would you please answer his question. This would be very useful for people who are intertested in your services

[stinkler]

I would buy from you even just for the quality control.
A turnkey lipo pack would be even better.
Im kicking myself for going 8ah packs. They are too stinking big.

so per 5ah chunk
based on your 50$ pack, 50$ lvc/hvc, 50$ breaker pricing.

12s 50v 5ah 100$ | 10ah 350$ | 15ah 500$ | 20ah 650$
18s 75v 5ah 150$ | 10ah 450$ | 15ah 650$ | 20ah 850$
errr plus shipping and slave labor.
Is this right? My math is crap.

[LI-ghtcycle]

This is a GREAT idea!

Wish I had your courage methods, but I've been warned away from shipping batteries as a business with out a huge amount of liability insurance, so I'm glad you are able to do this!

[visuthdy]

Hi Methods,
I'm interested in 4 -6S packs to make 12S2P battery pack for my ebike project. I've already had a bad experience once with hobbyking. It would be nice to the the guarantee of working packs delivered to me

thanks.

Hey, still offering these?
I would like to get a 20s2p pack... Is this the best place to look?

go to methtek.com for details

[Dudeofdoom]

I like the Idea....but batteries are a pain for shipping for non-locals.

but how about making a lightweight battery holder with the the electrics enclosed and pigeon holes for the batteries
(like those funny old square holders that took 4 AA and had a nine volt battery terminal on the top.)

Then people could source batteries and you don't have liability.

I could not give a shit less about being sued

I am fairly certain that one of the biggest problems with innovation and business today is that everybody is preoccupied with liability, political correctness, safety, and short term profits. F*^k all that.

When I am making a decision I ask myself: "What would Tyler Durden do"?

Sticking feathers up your butt does not make you a Chicken, and I dont want to die without any scars.

With that said - who wants to buy a hat woven out of firecracker fuse with a sparkler on the top?

Love the movie and that quote, one of the finest!

At first, I thought this service would not fly, but the more I think about it, the more I realize not everyone wants to deal with HK and the waiting etc.

I hope you are able to get a bulk deal from HobbyKing for the Turnigy packs.

[RallySTX]

Everything on the Methtec website but batteries. I just ordered a frame bag from Canada, and would rather give my money to Methy than HK. Is there a supply yet?

I think methods has not made an answer on this yet, but I would guess there's no chance he'd be supplying HK LiPo. To make it worth something he's have to test them all, and his time would add up, and then the costs of the LiPo would be much higher than HK. And liabilities dramatically increase when supplying lipo.

Eitherway, your money would be going to HK or maybe HK and Methods, because for LiPo I don't know of any other good and affordable source.

This would change if methods ever gets into supplying some of the cooler chemistries. Still, doesnt seem up his alley of interests.

(>.< let me continue to reply on behalf of methods. Sorry, he can speak for himself (and matt I guess) and eventually will.)

There is only one cooler chemistry ATM. And thats only because its safer and more energy dense but not as power dense!

If you are thinking of the Li(NiMnCoO2) chemistry, it's power density isn't too far off A123s, maybe 7% less? But definitely less than HK LiPo, yes. Plenty enough for e-bikes, that's for sure.

I've been using the Turnigy 40C LiPo in my battery packs and they deliver remarkably high amps with little sag. They don't have the gravimetric energy density of the 20C LiPo (about 160 Wh/kg) but I think they do pretty well (140 Wh/kg).

A while back I started putting together custom packs for a few local guys and some from ES but I haven't had much time lately to work in that realm.
We may still offer some kind of battery support in the future but right now we are both strapped for time.
I do have some battery packs built up out of some emoli cells by some crazy old guy that I may put up for sale after I have fully tested them.
They are something like 10S5P packs made from single cells.... figure around 10Ah.

[Kris B Krunch]

Hey Methods, are you still doing this? I'm very interested, not quite sure if I want to tackle building my own lipo pack or not. If you don't still do this, I think I'd at least like to get your battery protection kit.
I live in Canada, but very close to the US border and have a US mailing address that I use all the time.

Thanks

ps, I'd pm, or email you, but couldn't find that anywhere.

[Ryank]

Could we do this for the 10S packs? Those 5 Amp (5000MA) seem like a cool size/weight......

[methods]

We completely dumped this idea and instead we are going to offer a full kit that people can use to build up their own pack. Our kit will have the balance tap parallel boards (or LVC/HVC protection boards), buss-bars for paralleling the high power, etc.

Going to be a while tho as everything around here moves as slow as snot while I am trying to build my hooch in the woods.

Good call man. It's just too hard to assure n00bs won't do something to blow themselves up, despite your best efforts. A kit ensures at least the most basic understand of what's going on.
