Somebody wanted a battery!

[Occulta]

Maybe this one will fit the bill :eyepop:

100,000mAh with 5V, 12V, 16V, 19V & 24V output.

No idea how good it is; just a FYI

In awe and gasping for breath. I want two!

[GTB_an_Owl]

it's only 3.7 volts 100amp hour

It would still be 30Ah at 12V (assuming the internal converter works more or less without loss).

Cheers

My wife works in the UPS ( Uninteruptible Power Supply ) business. I can get a 600 Amp\hr battery anytime ... if I could carry it !! About 60 kg !! :eyepop:

Just FYI though, modern UPS's work at about 95-97% efficiency nowadays. Older models used to be around 80-85% at best. Electronics and control has evolved a long way.

What intrigues me is it is only 2.5kg ( incl case )????
I know LiPo is lighter than LeadAcid
but can you get 100Ahr at 3.7v with that weight of batteries???

Hi Andrew,

LiPo has an energy density of ~ 250 Wh/L while lead-acid has 80 Wh/L

http://www.altenergymag.com/emagazine/2012/04/a-comparison-of-lead-acid-to-lithium-ion-in-stationary-storage-applications/1884

This figure is in litres, so weight for weight, the differential is even higher between LiPo and lead-acid.

The big question for me is safety - LiPo batteries must be carefully controlled for charge current and temperature or they can get very hot and self-immolate. And they must not be discharged below a certain point, which means the battery controller must be quite a bit smarter than an equivalent lead acid controller.
