I also had to consider the safety of the higher current batteries. Since part of my commute involve taking a train that goes underground, I thought about the "what if" scenerio if there were a short in my wire or battery system while I was on the train. Not many places for me to dump the pack while in a underground tunnel Hence, I chosed the other chemistry battery.
