I already spoke with the batspace guy like 3-4 months ago.
If nothing changed till now the best thing they are supposed to have is 20ah 10c continuous NCM wich are made by EIG. Not sure if the price is going to be good.

5.6kg fully assembled 40amp continuos (20Ax2)
I would risk on two of thoses myself I, but I already have a ping.
