just been doing some more testing. [>:]

Take a look at this lott 10 packs of 4s 2100 cells. these aint cheap (£90.00 a pack but there 20c Yes 20C ) they are as hardy as the 340s

the eye are about 25% heavier than the 2000 cells and a fair bit larger but they will give 45A!!!

i have tried to test a pack to distruction (not by under volting, thats stupid[:@]) but i was sucking 75 amps out of one pack and only noticed a volt drop sag (down to 2.7volts per cell under load) but they recovered instantly when the current was dropped below 30 amps. this will obviously cause long term damage but if there kept at 40amps or less they should be good for a hundred or so charges.
