We have been using A123s for some time now in THz and Sam and Grant are currently finishing off a couple of 4S5P A123 packs for Tiberius.



Packs are 13.2 V, 11 Ah and weigh under 2 kg each.
Compare with a 13 Ah Hawker Genesis - 4.9 kg, with effective capacity of only around 7 Ah at the rates we are discharging them.
