There’s too many options available to know any specifics on a story like that. Some pros are running 2-36v lithium’s parallel, some are running 3-12v. I think it would be just about impossible to kill 3-125ah lithium’s in 2 full days. I’ve heard of guys killing 50’s in a day, haven’t heard of anyone killing 100’s in a day.

You want to discuss something with Jason and help our group learn, please do. What you are doing is calling a guide who has been on this forum 20 years and always been helpful, a liar. I would call that BS.

I'd say you're on to something about all the graphs not being wired to that battery. Math don't add up otherwise. A single 12" with livescope would make it all day but not 3 12's.

Not calling him a liar at all, but with his setup the math doesn't add up. Now he even says they may not all be wired to that battery which is a very high probability.

You need to work on your wording.

And some people need to learn math and electronic skills.

And you need to learn to show your fellow members some courtesy.

That would be some good info to know, at some point I'd like to go lithium but don't have the knowledge of exactly what it is I need to put in my boat to get this kind of performance.

When you think you are ready, it would be best to contact a lithium seller and they can help you decide what’s best for your situation. Different batteries require different chargers and it can get $$$ quickly.

Only asking because I am unsure and after reading some of the above discrepancies I was even more confused.

Are lithium batteries not like conventional batteries in that you have a battery that has x reserve capacity and it regulates discharge rate (as in 50 AH, 100AH, 125AH) if so that may explain why one brand 50AH battery may last all day and others will not due to reserve capacity.

With what little studying I've done so far; I've found out there are three types and that may play into why some that appear on the surface to be equal may have different life spans under load. That will just take more digging to really sort that issue.

They are supposed to be rated for the number of hours that they will last, there is some discrepancy between brands. I’ve read quite a few post about the Amp brand lasting longer than they are supposed too. Some brands, such as Ionics, have a BT app and you can see how much your charger is putting out and how much drain your graphs are pulling. Pretty cool feature to have.

They don’t have cca ratings like lead acid, although some put it on the label, but it’s not a true number and they don’t have reserve capacity. When a lithium gets down to approximately 10% of capacity (this number might vary by brand), the BMS typically turns off the battery to keep from being damaged.


Then you can get into some batteries that have 16v’s, the graphs tend to use less amps with the higher voltage. But if you have Lowrance graphs, they want a voltage regulator installed if you have 16v batteries. I don’t see the point in them (16v battery), but some do.

Be aware that 16v batteries require special chargers and recommended special wiring and should not be used on starting batteries. Just from what little i read.

16 Volt

Dan, how is the Noco charger doing for you? I am considering the 10x3 charger and would appreciate hands on experience opinion of this charger.

Thanks...Richard

Noco replied to me today and said my gen 4 4 bank is not lithium compatible- I think for now I am going to go with an x2 and revisit the lithium’s in a few seasons.
