Scary-Big New LiPo....

[xyster]

25ah cell for $120. Only 1C though. Wish all-battery would get with the program and start selling LiMn and LiFePO4.

There are so many typo's on their's & Batteryspace's web site that I always take their figure's with a mental asterisk- *to be verified.

However if the 100A rate on this 20 Ah lipo cell from Batteryspace is to be taken as gospel, then plunk down a thousand dollar bill, get ten of these bad boys & yer off to the races.

I'm no smoker but one cell is a slab about as thick & 50% longer than the size of a pack of cigarettes?

With those proportions, at that price they should simply silk a pic of Ben Franklin on the side.
Actually that's unfair, it's cheaper than that.
Given current exchange rates Bobby Borden will do.

i'll have 21 of those cells please only becausce 21 cells is about $10 more expensive than 20 cells

$2300 USD for a 77.7v 25ah battery pack - not bad!

wonder how much extra the BMS and charger(s) are?


i hvae to say there are a lot of stats for this battery on the page - which is good. I notice the 0.2c discharge rate at 25ah :S

Those 20ah 100amp BS cells look great for those who want the highest capacity for the least weight and smallest physical dimensions presently possible, and are willing to trade some fire/puffing risk. They also sell 10ah and 8ah 5C versions:

Lezsee....
420 grams/cell X 20 cells = 8.4kg (18.5 lbs) for an 80 volt 20ah pack. A similarly-sized pack of A123's would weigh 70 grams X 168 cells (24s7p should give about the same voltage and usable capacity) = 11.8kg (25.9 lbs). And the physical dimensions of the lipo pack -- I'll skip the figurin' -- would probably be a lot smaller. Could make a great backpack battery pack.

they seems to be interesting, but i keep my trophe for the A123 with:

168cells that would cost around 1700$
that would give 840A burst and 280A continuous WITHOUT any danger 8)

840 amps without any danger, eh? :lol:

Danger you'll suddenly find yourself in orbit without a suit....

Even bigger 50AH Li-Po:

(I've been checking the new products sections because I'm anxious to see LiFePO4 or LiMn in a prismatic form factor widely released by the cheap-o vendors).
