Agree with Chuck and Randy. The DIY approach many of us have with regard to our boat systems is not likely to be adequate for current Li batteries of which I know nothing except they can be charged rapidly and they keep going rather well until they don’t! When the battery and charger manufacturers agree on some standard that a boater can understand without an EE degree, it might be time for Li. Until then, I will pass. I will stay with my simple Lead-acid batteries and standard battery chargers/alternators whose ‘bugs’ have been virtually eliminated during the last CENTURY of improvements to both. OTOH, when Li batteries are as straightforward to hook up and charge as lead-acid, reasonably priced compared to lead-acid, available everywhere, etc. I will buy them as a better solution—not just because they are the ‘latest’ in battery technology.

The cost of Lithium batteries and all the necessary power/charging management devices, prohibits the purchase unless you plan to keep the boat for twenty or thirty years. I would only do it for a newer, bigger boat that can support enough Solar Panels to be off grid, like a big cat. Otherwise, keep it simple. Several YouTube sailors have installed the system and I can find those links if interested. Or google "Sailing Uma", "Ran Sailing", and/or "Sail Life" along with "lithium batteries" Chuck S On 09/14/2021 11:52 AM Randal Stafford via CnC-List <[email protected]> wrote: What’s the upside? I got seven years out of a pair of group 29s Everstarts from Walmart, just replaced for $90 each. And I just replaced the alternator on my A4, which lasted 49 years. But the way I use my boat doesn’t require having a state-of-the-art battery system.

I have to say I thought I knew this stuff and it seems massively confusing with a ton of directly contradictory information. One big issue seems that if the BMS disconnects for any reason, that will do a lot of damage to your alternator and perhaps other equipment too. Add to that my regulator does not have a specific lithium setting, I would need to get into the custom menus and try and make one. What seems to be the best bet is just to connect the alternator to the start battery and use a DC-DC charger to charge the lithium bank. Some of them also take solar input, so that saves me buying a solar controller with lithium settings, which is something else I don’t currently have.
