www.dronesdirect.co.uk
It is 45V, 6Ah
(this seems an awful small battery for a 6.5kG drone?)
The charger (BS65) for it is this...
BS65 charger:
dji-retail.co.uk
..This charger claims to be able to charge 2 x TB65 batteries and 1 x WB37 batteries simultaneously
(WB37 is just 8V X 5Ah)
WB37 battery:

The BS65 charge station says it runs at 992 from 230VAC.
But hang on....batteries should be charged at 1C and no more..therefore, the power draw from charging the 2xTB65 and 1XWB37 batteries should be no more than 580W, so howcome it is delivering 992W?
