1300kJ/kg Battery - from the Too-Good-to-be-True Newsdesk

This smartphone-sized pocket battery is being marketed for emergency starting of cars with flattery-battery-syndrome, but if the manufacturers specs are believable it would make a fantastic power pack for quads etc.  More than twice the energy density of typical hobby-grade LiPos (typically <600kJ/kg) and with a good punch of the current to boot! (50C, allegedly!)

At only $99.99 ($69.99 for pre-sale purchase - see website) it's not bad value compared to the lower energy-density Panasonic NCR18650B cells.

FWIW

Wait a minute, what? I mean......what? Did we just see a 7oz lipo start a car? What I want to know is how they charge this from a 5V USB charger.....

Interesting product.

 

However it is still a LiPo battery and it would be impossible to change the physics to suddenly double the enegery density. Most likely they are exagerating their specifications and in real life won't have this capacity. As a reference other LiPo batteries at 6000mAh weight at least 450 grams. Their product weighs less than 200 grams. That is just impossible in my opinion.

The large alligator clips would weigh down the quad/plane a fair bit though :-)

Steve the battery you have linked will not suffice for our hubgry energy needs. To little contant current. As for the smart phone sized battery indeed specc are overwelming but actual tests are missing. I could also make a funcy site advertising a 20A battery weighing 200g and all of you here would be throwing parties around it. I want to see a person actually flying it and I am gonna contact them personally to ask more info and propably a sample on a distributor price to prove them right or wrong. If they are right all we need to do is a serial connection and voila 6s at 6A weighing 500g. Another question is how much charging c rate can the battery accept.

Interesting that there is no arc when paralleling across lead acid.  This suggests that here is little difference in terminal voltage (ie - lead acid is above 12VDC).  If there is no difference in terminal voltage, then the lead acid is not flat.

I would not retail a product like this to the end user.  Too much to go wrong.

Smells like BS to me!

I just ordered one, I guess I will have to wait and see how it works.

i wanna see how this actually performs
