Just spotted these red headway cells which I heard are high discharge. $15 a piece for 8AH seems pretty good? https://www.ebay.com/itm/Headway-38...-/184596206364?_trksid=p2349624.m46890.l49292
That price is good, those batteries are good. I plan to switch to these whenever my 15 Ah cells start dying off. My caution would be the description that marks them as used - I know Marty bought some of the blue cells off ebay and had at least 3 of 8 show up dead on arrival - maybe if the seller was willing to check the voltage on each, if they are in the 3.1-3.2 ballpark they should be fine, if not I would probably pay slightly more for something that I would know won't have a reject rate (or is at least marked new or had some sort of return policy). Last year I ordered a few headways from a Chinese website that never produced, so I stick to more reputable sources.
