Application Kit from Altairnano

[Lock]

Anybuddy here played with the Application Kits from Altair?
http://www.altairnano.com/appkit

http://www.b2i.cc/document/546/117502.pdf
24V 50Ah
Altairnano’s patented nano-lithium titanate
Max continuous discharge 300A
Cycle life at 2C charge and 2C discharge 100% DOD 25°C, >12,000
Operating temp range -40C to +55C
Expected calendar life 20 years...
25.3kg (ouch)
etc

Basic kit config:
(1) Altairnano Advanced Lithium-ion 24V 50Ah Battery Module
(1) Connection and Control Unit (CCU) – Contains Battery Management System (BMS), Charge and Protection Circuit
(1) Netbook (Factory verified communication with BMS including detailed system performance monitoring)
(1) Set of user guides and installation diagrams

Kit Options:
Additional 24V 50Ah Modules
3’ Harness Kit to connect multiple modules in series
Advisement on recommended cyclers

Mostly wanna know if they're "giving away" these kits at promo prices, or...

tks

Looks like it's got possibilities... is it real? Is it available? What is the cost? If it's economical it could be another game changer.

If they're only going to offer 50 Ah batteries, then just to get up to 48V (and this seems to be the absolute minimum that anyone here would want) then you're talking 2 batteries, or 51 kg (114 lb) of batteries! And I thought my SLAs were heavy...

Even 48V 20 Ah is going to be over 44 lb. Gotta be some way to get that weight down.

They describe it as "Battery module with integrated heat sink designed to maximize efficiency of external cooling infrastructure for demanding and repetitive duty cycles..."

So dunno how easily the sink could be stripped away or watt the lack of the sink would do to performance but at it's heart it's just Nano-lithium titanate cells like the Toshiba SCiB
http://www.scib.jp/en/product/spec.htm

24V x 50Ah... 1200Wh of the SCiB cells would weigh 17.8kg, if they have similar energy density to the Altair cells. It's possible the hear sink (case?) may be 8kg or so.

Quite a diff. in claimed cycle life though, 6000+ claimed for the SCib vs 12,000 for Altair.

Heatsink for 5C discharge???

 

[redorblack]

a 72v 100ah pack 3s2p would weigh a bit over 200lbs. Compared to my 6s1p SLA setup where each battery weighs 78lbs... for a total of 468lbs... I'd shave off 266lbs and have a battery solution good for the next 20 years?

Maybe that "little" amount of heat resulting in a temperature change (on charge and discharge)* is a major determining factor in battery life (and maybe the AllCell folks really are on to something, too).

Ah, ha! Now I get it. I am always thinking in terms of e-bikes that it didn't even cross my mind that this would be useful for an e-motorcycle (do we call it an e-Bike?). Now the real utility is clear. Sorry about that, losing 266 lbs does seem like it might make a little difference, after all.

I looked into AllCell. They are within the US which I would rather buy from than waiting a month for a battery from China.

Eh, depends on your load. If you cruise along pulling 10-12 amps all the way to work it's fine.

Wouldn't consider anything less than 20c for a fun vehicle though. 8) Even though I may only pull 20 amps on it, I want light weight on the dirt bike. Much better for that use, to just get a battery that doesn't waste watts heating itself up.

Back to the Altair stuff, 12,000 cycles does sound interesting, even after the standard cut all claims in half procedure. 2c would be 100 amps, so that could work for a daily driver motorcycle. Say your range was 30 miles, 6000 cycles would be 180,000 miles. Enough to wear out several motorcycles.

The way I treat em, ( constantly doing something dumb) I'll jump for joy if most of my HK lipo lasts one year. But, I don't have that much money in em.

Well damn gotta keep the standards high or drink alot of Ice House to stomach through it.

ahhh - pedal assist - the ice house of ebiking
