I am in a QUANDREE as we Alabamians call it. Whether I can spell quandary right or not I have found recently that purchasing lithium battery's for a Allison Bassport boat is an adventure in education, guesswork, and modification in some cases. A person is fine, other than high cost, if they are simply going from 24 volt systems using lead acid type battery's to lithium, but the plot thickens like mom's custard pie when you go from 24 volt systems to a 36 volt system. I've been trying to get prices on a single 36 volt lithium with 100 AH, or double pair of 36 volt 40 to 60 AH Lithium Pro's for 2 days now. Not knocking Lithium Pro nor their dealers at all. Obviously this is still an infantile industry with growing pains and such to deal with. Those guys are just dealing with the growth in sales the best they can. I hope that is the case as I'd hate to run my business forever like that. Customer wants price and deliver, I give it to them quick to sell while the buyer is ready to drop the money. There are many choices to buy 12 volt lithium's so you can series them for 36 volts but then you start looking at putting battery's in places in a nice boat like a Bassport where battery's were never meant to be, and then running wires, where they were never meant to be, to get it all connected. I may have to go there but I would much rather not have to. I wish more manufacturers would see the rise in 36 volt TM unit sales and build 1 group 31 size battery large enough to handle a day on the water. I've heard over and over how I really need 2 each, 36 volt battery's paralleled to give a "not a doubt you are ok" day on the water. Hopefully today my quote will come back. And yes I have been to all the websites and I know I can pay list price off the website but A. I'm not ready to drop over $4K on 2 battery's yet counting the charger, and B. When will I get them. 1 week, 1 month? Who knows! I'll go back to AGM's before I'll stick my hands up and let my pocket get completely emptied or before I start cutting holes in a nice boat or before I have to wait forever till more lithium is mined in Africa to get mine built! LOL. Vent/Comment over. LOL
