for a few days now, i've been thinking about an electric motorcycle.
nissan leaf modules seem to be a popular choice, but by now, they're considered old tech. the better batteries now use NCM and NCA chemistry, but my understanding is that they also tend to be a little expensive. my interest isn't with the energy density of the batteries so much as the electrolytes additives that companies are adding these days that boost cycle life to upwards of 1000s of cycles, which is a huge improvement from 2010-2011, around when the first nissan leafs came out. i assume that these 2p2s nissan leaf modules come from the same time period, and nissan is apparently phasing out these modules in favor of NCM chemistries for their future productions
18650 is another option, but it would involve a lot of spot welding and a lot more work, compared to having larger packs that can stack nicely against each other, and be easier to work with. perhaps some people sell 72V 18650 packs that can be used. that would take away a lot of the leg work on my part.
but that's the extent of my knowledge as far as what options are out there. are there good recommendations for cost effective, easy to work with battery packs that also use somewhat modern chemistry, or am I dreaming?

this is what i mean when it comes to electrolyte additives. jeff dahn is the real deal. look at that man.. they're tripling the cycle life of these batteries with that secret sauce.
