Hi

Anyone have any experience of these tiny batteries?

Looks insanely small compared to everything else on the market. ..

Cheers.

It'll be 13S3P, so 39 cells, which weigh about 50g each, so about 2.3kg by the time you add the BMS and case. I've no experience of them, but they must be the 3400mah cells. They give about 5A each, so you could get 15A out of that pack if the BMS allows it. The sag would be considerable at that current - about .3v per cell, so 4v total.

Tiny battery, but you don't arf pay for miniaturization, after import taxes, courier handling fees etc...

It's could potentially be the very latest NCR18650G at 3600mAH:

I however doubt it as they are very expensive and with such a small pack you'll stress so much the cell that you'd only get 3AH out of them at 5A / cell.

True capacity at 15A is about 9AH, which would be the same as getting a pack with 3C type cells such as the INR18650-32E:

I'm considering getting these cells from them as soon as I moved to my new place. I have a spot welder I can do few packs

Let me know if you fancy making extras to sell
