Eue to the weight factor and the ability to almost discharge down to "0" w/o a drop in voltage, I am going to switch to Lithium this winter. A bit pricey, but will be worth it in the long run, less weight, better performance, longer run time. Can't beat that ! TD, do a write up on your Lithium battery so people can get a good read on them !!So far, I have only made 4 or 5 trips with the Lithium. But I definitely notice some positive comparisons.
1. Much lighter. My series 27 AGM batteries are over 65#. Getting tougher for this old guy to haul them to and from my tube. The new Lithium is only 24#. Definitely an improvement in carrying...and less weight in the tube.
2. More power longer. Although the series 27 AGMs are rated a bit higher in amp hours, they do not deliver a constant output...and decline a lot...almost failing at about the 40% capacity level. I have had a few tube trips when I was barely moving by the time I hit the ramp after about 4 hours of fishing. The lithiums put out a constant 12.8 volts until failure...at 0% level. This gives a longer use on the water at a constant high level of output. I have already had a couple of high useage trips lasting almost 5 hours...and still had plenty of power as I brought my tube back to the ramp.
3. Faster recharge time. Only about 1/2 to 1/3 the time to fully recharge the lithium as compared with the AGM after a trip of similar duration.
The new lithium will probably outlive me. But I am more than pleased with my decision to pay the extra for this battery.
