how I think of total power capacity is telling me I should build the 1080Wh pack that the calc tells me will give me 72km range.
3x power level is throwing me off though, would I theoretically get more range out of the high amp pack? is the 50A 25Ah 1080Wh pack even worth it? or is it the longer lasting pack?
my main priorities are range and uphills.
I already own both cells so it’s not a matter of cost. the cells I end up not using will be repurposed for an eBike.
packs will be made with direct discharge and a charge-only BMS
It depends on your settings, but I’d say use the LR2170LA on the esk8 and the 50E on the ebike.
If you kept low settings in your ESC, no more than 24A “battery max” per ESC (two motors) then the 50E would actually be better in the esk8. This would still be plenty powerful. If you plan to exceed this specific setting than I would use the LR2170LA no question at all in the esk8. Keeping that number low also buys you more range.
I’ve done a few tests on hills with a 12x4 pack of 30q (same drivetrain I’m using for this pack) and I’ve found most hills don’t demand more than about 45A so I think this would be okay.
IMO, with Samsung 50E’s (not 50E2 or 50E3) the Lishen LA will be the better choice at anything over about 10A per cell, perhaps even less. There’s a lot of voltage sag with the original 50E and there are a lot of old 50E’s out there too.
