i use interstates as well ..I get mine at senters in plaistow ..Milford marine has them as well..not sure where you are located but just do a google search for a dealer near you
Aren't you all missing a completely new style of battery? I'm VERY new to the electronics game but isn't there a LifePO4 style lithium batteries on the market that can draw a much more consistent amount of power through the life of the battery, weigh less than half of the lead acid batteries and have a longer shelf life? They come at a very steep price but I recently ponied up the cash for one since I want my setup to be as portable as possible. Unfortunately in the situation we are in I can't get the thing until May.
My buddy got one for his yak. $800. Too steep for me.
For my purposes I could get away with the 54ah but yeah cost double the amount of the trolling motor. Weight was a big factor in my decision since it will be used in an inflatable raft or my kayak.
You guys like the flooded lead? I am not in favor of having to add distilled water to 4 batteries so I stuck to sealed on the bass boat. My trolling rig has 4 flooded lead. They probably need distilled water. Wouldn't mind that flooded lead price though.
I also have 8 deep cycles too and while I could afford to replace them all with lithium, it would be a considerable cost...money better spent elsewhere....like the 1400 I just donated to tackle direct last night
Yeah the short term cost benefit is good, but I bet if you do the math on lithium it may win that battle over time. Especially when you consider the durability and weight benefits of lithium. I do sometimes pound the ever loving daylights on my boat, especially on the salt, and the batteries are what makes me cringe the most. Lithiums are more or less bomb proof. But if you take care of lead acids and make sure they are tied down good they are pretty stout.Do they make great on board chargers for lithium batteries? I'm sure they must.I made a great 60 amp hr. LIfepo4 battery ammo box for my ice shanty last season, it is awesome but that is obviously a huge bonus for the weight factor. But for some reason I didn't consider it for my trolling motor install?
I did have fun today in the wind with spot lock. 36v's and 110lbs of thrust moves.
