Our Jonboat power system had began to fail, after 8 years of use. We run this thing great distances, sometimes several miles, so we needed a dependable battery system. I decided to give the new deep cycle LiFeP01 batteries a shot. The battery we selected is rated at 100 Ah, will hold the output voltage steady for its full capacity, and good for over 5000 charge cycles! The series 27 battery we had weighed almost 80lbs, this new battery weighs 20.8 lbs!!! Wow, what a difference... and the usable battery power is amazing! Here's a few pics...
I recently jack-knifed the trailer and bent the spare tire bracket. I repaired it...
The new battery in the boat. Guess I need a smaller battery box, now!
