Diy lifepo4 battery box12/24/2023 With blades it's one box around the whole set, one heat transfer plate under the whole set (if active thermal management is used) - that's it.In the past few years, the cost of solar panels are decreasing drastically but the overall cost of the Off-Grid solar system is still significant. I have no idea why blade cells would need to be individually encased or individually thermally managed, and no one does that with any kind of cell, even pouch cells. What they are planning to offer (it doesn't exist yet, except as that very pretty mock-up) is a set of 6S modules (six groups of cells in series within each module), intended to be used to build replacement packs for the Nissan Leaf. Their ridiculous product web page only provides more videos - they appear to provide no written information, so the whole operation appears to be a joke. Watching the first few seconds confirmed that it is irrelevant: despite the use of the word "blade" in the name of their product, this has nothing to do with blades. I had not watched the video before commenting, as nothing about the title slide suggested that it would contain useful information, and the image doesn't even show blades. Blades are individual cells, from BYD or another another manufacturer copying the format, intended for use in a cell-to-pack assembly without an intermediate module stage of assembly. With blades it's one box around the whole set, one heat transfer plate under the whole set (if active thermal management is used) - that's it.Ĭells are conventionally grouped into modules, which are individually enclosed to varying extents and can even have individual cooling elements, but not when using blades. That, and you posting and running got you the spammer accusation.nothing radical or new and seemed totally blind to the applicability in car conversions that cannot have these cells under the floor for most car conversions or that don't have the sheet metal width to accommodate two across by the time you connect, isolate, and cool them.even in the trunk.Ĭlick to expand.I have no idea why blade cells would need to be individually encased or individually thermally managed, and no one does that with any kind of cell, even pouch cells. If you want to go with that "availability" route, there are a gazillion sources for LG chem cells with the Mach-E and Bolt-EV dimensions on Ali-xxx that actually will fit in a conversion. You'll notice in the New Zealanders' Nissan Leaf module replacement video, above, with these blades.they appear to be liquid cooled, but maybe not.Īs far as getting spammy and a "reliable source", I submit nothing on AliExpress is reliable as a source and it's usually an order consolidator in an apartment flat in Shenzhen that you're dealing with, not the manufacturer that has crazy-high MOQs, who you'll find on Alibaba, not 'express. Thermal management all depends how quickly you want to pee away $12,000 in battery modules and whether you can wait four days to charge them, and how much current you want to pull before smoking them. Even lead-acid can use it to extend life, improve efficacy, and increase charge cycles. People, by the way, use "Tesla" modules because they've drunk the Musk Koolaide and they appear easier to liquid cool. Most cars are also not 80 inches wide for two boxes of your 38's side by each *anywhere". The Tesla modules are 10 inches shorter.so you can just get two across, or one longitudinally in the engine bay, two across for 26 inches. Most engine bays will not accommodate a 40+ inch battery box dimension.
