[QUOTE="hispls, post: 8786147, member: 614752"] Not sure what you're paying on the headway cells, so they might be OK, but their nominal charge rating is 3C (3x your amp hour rating) so if you get say a 200A alternator you're probably going to hurt those batteries if you don't have more like 80AH. They claim you can charge them harder under the right temperature conditions but personally I'd plan around being safe to operate in any condition as opposed to having to make sure the temperature is within a certain window so you don't destroy your cells. Max continuous discharge is supposedly 15C which leaves you at 600A draw out of a 40AH bank which should just about cover your 6000W amp but you'd be running them really hard. Bear in mind the further you go beyond those nominal rating the worse you can expect your cycle life to be below published. I'm personally a big believer in LTO, but the headways should function if you size your bank appropriately and if you're getting a decent price. [/QUOTE]
