the 5Ah one is listed as weighing 0.3kg (or 10.5 oz)
This is just what is listed, I haven't got one yet and assume .3Kg may be a=
"rough" figure, it would make them a little heavier than most Li-Ion's. It=
equals about 8.1grams/Watt, 5to6 grams/ Watt is more typical for a Li-Ion
4 AA's give about 11-14Watts (mine weigh just under 4oz)
As against 37watts for the Li-Ion 5Ah
