300ah Gel Battery
If an LFP battery does catch hearth, you don’t need to be near it. The specification additionally claims % SOC to 0% SOC cycles so the purchaser would assume you possibly can actually go to zero% on each cycle. No one is aware of the place the ABYC standards will land on Li-Ion batteries being used on boats but, but the committee is getting close. If you might be moving into into LFP, pre-ABYC standards, as I have accomplished alone vessel, be ready to be denied insurance coverage and be capable of take up that value if your financial institution does not meet these standards.
If you need LFP and don’t have the ability to DIY, of those three firms I can definitely suggest the Lithioncs/OPE Li3 system. The Lithionics/OPE Li3 battery system at the top of the list for us and checks each box for a marine specific software. I personally have essentially the most expertise with Lithionics, Genasun and Mastervolt marine LFP systems. Factory Integrated Lithium-Ion Systems – Victron & Mastervolt are about as close because it will get as a result of they sell both the charge sources and the LFP batteries as a factory built-in system.
Nothing mistaken with gambling just have the ability to settle for to shedding out, when you chose the incorrect product. Trojan’s entry into LFP, I consider, helps to legitimize the underlying LiFePo4 chemistry. There are also other massive lead-acid US battery producers are working on this too. Up till Trojan entered the LFP area, the “drop-in” market has been flooded, aside from for Lithionics & Battle Born, with US based mostly sticker application firms. 4) If or when the cells do turn out to be out of stability, most actually because the cells were not well matched to begin with, the mA level balancing circuitry might never catch up.
I recently watched a video by a extremely popular YouTuber the place he was touting a “very good deal” on a drop-in battery. It was absolutely not a drop-in battery, and had ZERO BMS PROTECTION!!!! As can be seen, underneath Bureau Veritas standards external communication between the battery and the remainder of the techniques such as charging is a requirement. If the producer uses 5Ah cells, and a few do, we then solely need 80 cells whole, and a hundred and sixty spot welds or bolted connections to doubtlessly fail or work free.
The BMS disconnecting whereas inverting additionally damaged his inverter/charger. When I pulled up the spec sheet on the 300Ah drop-in battery he bought, the problem turned crystal clear. Compare that to most of the drop-in batteries being sold on the market which have very low-current handling functionality due to the usage of FET primarily based switches. The manufacturers constructing “marine particular” LFP batteries know what a cruising boat wants when it comes to present handling and so they engineer this into the product.
If you want to conduct a DIY construct, we additionally strongly recommend buying cells from Carl at Electric Car Parts Company. Carl spends a lot of time in China, on the factories, and solely buys premium cells.
He felt snug because it was, what he thought-about, a “respected producer“. He quickly destroyed three alternators and the BMS stored disconnecting when he was inverting along with his giant 3kW inverter/charger.
Lithionics/OPE-Li3, Victron & Mastervolt all build LiFePO4 batteries for marine particular purposes. These systems are nicely engineered, well executed but additionally at or close to the top finish of the pricing spectrum.
