No, the zip tie was what held mine back to only 3300mA. I'm hanging it all out at 3400mA now baby!
CMAG, I tried pushing the latch pin as far as I can push it with my old Palm stylus, and didn't see any potential problem. Another thing I did find is a secret hand written number under the spring coil making contact with the anode. I cannot divulge the secret code however.
Good to hear the lock does not self destruct, I pictured pins and spring flying off never to be found.
No number I can see under spring, maybe it will show up at 3.4 amps
