I am using and have been using a Bioenno 12V 12Ah LFP Battery (ABS, BLF-1212AS) for a few years now. The price is far more than a typical SLA battery but the battery run time and the overall weight of the battery outweighs the additional cost of the battery.

As far as where to mount the battery.......mine is mounted inside the kayak right under the seat and just aft of the center hatch, it is easily accessible while sitting. The battery bag that I used is the Ocean Kayak Battery Bag, its about $35. The Bienno battery fits perfect in the bag, it almost as if the bag was made for it
