You don't need 10amps. You'd only need that if you were putting a significant load on the battery or if you wanted to quickly charge it up. We're working with an assumably topped off battery that must stay topped off while we're writing to the ECU, so a trickle charger is all that is needed.
yep - i just flashed my 2011 M3 - and had a battery tender plus trickle charger hooked up - I made sure I was 100% charged up before I started and turned all unneccessary electronics off...
