[QUOTE="hispls, post: 8767145, member: 614752"] Which simply isn't a thing with LTO chemistry. You can see videos of them being drilled, cut in half with an angle grinder, being run over by a forklift, over-charged, whatever. These aren't like LiPo which can have the dangerous failures. Sure, running without balancing probably isn't optimum but again, even if they only last a quarter of their advertised life expectancy I'm happy enough and about 1/3 of the cost I have into my banks is just the copper, hardware, tools and time into busssing. I was probably the first guy in the USA using those for car audio so there really wasn't even anything on the market to balance 6s banks anyway. Wasn't worried then, not worried now. Building a small bank the only other thing to consider is "C rating". That is, how many times the rated amp hours of curerrent you can charge or discharge safely. Some of these cells (like the YingLong) are "rated" 10C which means you could charge a 40AH bank at 400A or pull 400A under load. If you look at the performance specs and cycle life specs they'll be some fraction of that max rating for best performance and whatever max rating you see published should definitely be considered "NEVER EXCEED". So for example, if you have 280A alternator you are going to need 28AH of a 10C rated cell to be safe, but if you double your amp hour capacity you'll get better performance and extend the life of that bank by about double. Again, these are rated to last 20 years or 20,000 or more cycles so I'm going to guess that even with some abuse they'll outlast anything we could have used prior to their invent. Some of the car audio branded battery companies are even selling tailor-made banks which they claim are fine to run along with stock or AGM, which is flat out ******** but they are likely going by the assumption that even with that sort of install they'll still outlast whatever warranty they're offering. Anyway, counter-sinking the bars is an option but an awful lot of work if you don't have access to a real metal shop. Congrats on the pending new job. Hope you're staying out of trouble. [/QUOTE]
