Yes, the c rating maters, but that’s a 12000mAh battery so with a c rating of 12 it’s a constant 144A output.
But how are you going to charge them?
I use 2 hobbyking zippy 5s 5.8aH lipos in series at the moment and charge them individually using a lipo balance charger whereas if you get a battery with built in bms you can just plug it in to charge the whole battery in one go relatively safely
that bms will work great. it’s the one i have as well. you just need to remember that you’re limited to 80a total discharge from the battery to the vesc (which is usually enough). if you wanna run more current to your vescs then run a charge only bms
One of the main design considerations between li-ion and li-po is the distinction between specific energy and specific power. Li-ion wins by a large margin in terms of specific energy (Watt-hours per volume), whereas li-po wins by a large margin in specific power (Watts per volume). Those lipos have about 0.33 Kwh per liter, where a 18650 pack has about 0.51 - A 55% increase. (And yes, that is taking into account the inefficient packing of round cells. It’s even better if you ignore that.)
On the other hand, the li-ion cell can only produce 292 watts per liter, whereas the li-po can produce 1200 - A clear advantage for li-po.
Thus the choice between the two comes down to a question of range vs size vs power. For a given size, you will get more range but less power with li-ion, and the inverse with li-po.
Above a certain size though, the power advantage stops mattering so much - You just aren’t going to use more than X amount for a given vehicle design - You run into other limits like tire grip and the ability to stay on the board. Above that size, li-ion is the winner because you have all the power you need, and 55% more range. It’s just a matter of figuring out where that point is for you.
TL;DR, li-ion is better for large packs, li-po is better for small light packs.
Yeah but you are kinda exceptional haha. For most normies/ cruisers a 12s4P is plenty. If you are upgrading from that you will have to need to pay attention to the things you just mentioned. But personally I think that kind off power is quite overkill hahah.
