Its a bit of a quandary Shakey..
In the end my choice to use them was based mostly on weight..
So with a Lead acid type battery that should only be drawn down to a max of 50% you need a battery twice the size of
LiFePO4 ( mine state 2000 cycles at 100% depth of discharge)..
100Ah LiFePO4 =12-13kgs
200Ah Lead acid = 42-45 kg
with a 36v system times that by 3 and you start to get the picture that i would be carrying an extra 90 kgs in the mid to front area of the boat every trip....its rather significant...carrying 130-145kgs of batteries for the trolling motor is just nuts...
Your battery guy obviously knows a lot more then me but I havent heard of any issues to any other boat components or accessories caused by the higher voltage of
LiFePO4 batteries other then Trolling motors...has anybody got any experience with issues here..?
If you also carry the same thinking of 2 to 1 real usable capacity over from good quality Lead acid to lithium then by using Calbs cells or similar to "make your own" the actual "real cost" of storage is not a hell of a lot more...it is however if compared to something like an Enerdrive purpose built 36v battery which really is a lot of money....
I hope I've explained that in an understandable manner...
Also I wonder if its the Trolling motor technology that isnt up to speed with the
LiFePO4 batteries rather then the other way around...just a theory and happy to be proven wrong if thats the case...
which ever is the case there are definite issues there and as mentioned by fishtragic its us that will be paying for it once out of warranty...
