![]() ![]() I think being an electrical engineer, its probably easy to forget how foreign electricity is for a lot of us when we first start down this path, and the learning curve is steep and not always intuitive. Time, someone already mentioned this, but I wanted to elaborate, its not just the time it takes to build the battery, its the time it takes to research suppliers, do due diligence on unknown resellers on the other side of the world, the time it takes to learn the basics of LFP, and for many of us, the time it takes to learn the fundamentals of electricity, batteries, etc.Though I have my reservations about how often we do this nowadays, I also understand that it can be liberating or comforting to not have to worry and stress over a bunch of little decisions, especially if you don't have confidence in your knowledge or ability. Shifting some risk/responsibility away from yourself, responsibility of building it correctly, responsibility for choosing the right parts, responsibility for setting the right BMS parameters, the responsibility for deciding whether 25f or 32f is the minimum acceptable temperature.While I personally, and many people here share your preference for the DIY route, I think you are understating (or misunderstanding the value BB and companies like them provide). But totally understand if you would rather pay someone $500 to drop in $300 worth of batteries and BMS and sell it for $800. That is literally TWICE the Battery for half the price. Right now for 429.00 you can get (4) 3.2V 200aH LFP batteries plus busbar plus shipping (8-12 days) battery from the same country BB gets all their stuff. ti guess they drop it all in the box - and slap a sticker on it. The battery and the BMS - and probably the container is all from China. ![]() I do give you points for saying "assembled in USA" and not MADE IN USA. ![]() and they may get more and more picky about warranty issues BB will start dropping their price to keep up with consumer pricing. ALSO YOU have to ship the BB back and forth YOURSELF for warranty. Yes a 10 Year Warranty on paper - but lets see how long that actually lasts until allot of caveats begin to appear. BUT would love to hear BB explain how they can do something that NO other LFP manufacturer does. and yes - it takes about 24 hours to charge a 200aH battery that way. at work when our LFP batteries MUST be charged on emergency equipment below 32F we drop our 60A and 100A chargers down to less than 3A. MANY ppl have asked BB this and NEVER got a good answer. The low temperature cutoff at 25F on the BattleBorns has never been proven to be safe - BB has NEVER told anyone how they are able to charge a chemistry that at 32F becomes bad. ![]()
