one of the reasons i purchased the Bixpy was because i couldn't get the Torqeedo with the larger battery right off the bat. Seemed very wasteful to me to purchase the kit with the 320W battery and basically not use it. I've been sending them messages for a while now asking for a bundle with the 915 battery, but they won't budge. If the sea trials on the Bixpy go well this weekend, i will forget all about the Torqeedo.
