The word is passing on !
The Pana's 3500 are out, ok, not a big deal in terms of numbers (1,1V at 30Amps) and with a strange shape to say the least.
Now the rumors are pointing out Orion 4000 ...
What did you know about that ?
Output voltage is going to have to take a significant increase, as well as capacity if the cells continue to gain weight. Otherwise, the extra weight is going to off-set any advantage of voltage or capacity.
I swear I could go as fast in stock with sanyo 1700 as with gp3300. well, almost.
