Hi,
But the prismatic cells are more compact and weigh quite a bit less per ah than the M1's. The 15ah pack of prismatic cells are 401g per cell. The 2.3ah M1's are 70g per cell. So 4p (9.2 ah) are 280g. Maybe another 20g per cell for the extra connections and the larger housing. So roughly 100g per 15ah cell more. So a 16s pack will be about 3 pounds more which might not be a show stopper when you factor in the convenience of having a larger pack.leamcorp said:The Mighty Volt said:I don't know why anyone would want to go below 10AH at all.....
Because if you don't need that capacity, why would you want to carry all that extra weight? My regular commute is 6 miles or so. And at that distant, I use no more than 2ah and certainly less than 4ah on days I don't pedal as much, so at the most, I would build 7 or 9ah pack for this commute (I do charge at work). And I do this all without BMS. The M1 battery is very robust and you have to literally drain the crap out of it to kill it. So if you keep a watch on its capacity, its will do you fine.
Also, I enjoy riding a bike, and as I went up in weight with 20+ah packs (and heavier motor to drive them - I do have a 40+ mph bike), the less I enjoy commuting on them. To me, that extra weight made the bike feel, well not a bike. So to each his own.
