I’ve got emtb…
Single motor 192kv 4.33 ratio (65/15), 9inch wheels and I would definately love to have more range with it.
I know there’s different needs/stats for longboards… but basically I think for emtb a battery of at least 250wh is needed… this would translate to roughly 10S, 7Ah battery.
Right now I’ve got about ~190wh battery. and 8-10km in some instances, is a bit too litte :\
So basically, this would translate as 120wh longboard battery minimum, though not sure how many ppl do long shots with their longboards… depends on the road and also on the intention for the ride…
~120wh = ~10s 3.5ah
So I think for e-longboard 5-7ah battery with 10s system, is a good ‘‘middle ground’’ (180 - 252wh)
Basically, the less intensively you discharge the battery, the longer it will live… Ideally, batteries probably should be discharged in 60-80% range. meaning, that you leave about 20% on the low end and also dont charge it up till 4.2v… more like 4.0v or so.
One more thing to consider - the bigger the pack, the more faster it is possible to charge it without ‘‘damaging it’’ (if the charger is capable enough…) More watthours/amp hours per 10/15/20mins to put back into the pack… versus slower charging…
