9Ah is fine. Half of my boards are 5.5Ah

maybe 20 miles or so, depends on your weight and alot of things

Separate but not because of the simultaneous thing. Which you can do if separate.

It’s mainly because BMS capable of proper discharge current are more expensive. Normally only charge is needed for BMS. Discharge is handled more or less on the vesc side.

Please stop offering stuff for sale in non-sale threads. I’ve seen you do this a few times now.

So loopkeys… mounting them. I get the whole idea of them but for a square mount how do you go about cutting a square hole in a Big Ben enclosure?

A dremel is probably the best bet. Just start small and work up to the required shape to avoid blowout/cracking.

The USB port on my slave ESC has shit itself. If I set new motor current settings on the Master, do they get copied to the slave?

Worked fine last night, went for a test ride this morning and now the computer is saying that the device has malfunctioned

I’m not very familiar with can stuff but I’m pretty sure vesc tool has a can forwarding option to modify the slave settings… If a more experienced vesc’er could chime in that’d be ideal.

Yep i figured it out with can forwarding :ok_hand:

Playing around on the 3D servisas Cacalacor I noticed that the lower you set your n for batteries in series, the higher your torque. For some reason I thought that the trade off between P and S counts on your battery was top speed and range, but is it top speed and torque? a 12s4p battery will have shittier torque than a 13s4p (assuming the same cells)?

Torque is motor and motor currents. Has nothing to do with P and S count, but total cell count. More cells, more total watts, more power can be sent to motors. S count increases voltage which increases max motor RPMs for a given system.

dude I was having a mental melt down. Like my whole physical nature was deteriorating at the seams. Thank you for saving me :+1: :+1:

@BluPenguin one thing I’m still confused about thought is how cell discharge affects torque. Does it? Like will a HG6 20650 rated at 30A punch more torque in a 12s4p config than 30qs? Because I thought that rating was just the amount of A it can theoretically discharge before overheating

Well, torque is directly based on motor current. Motor current x RPM is power. On the battery side, S count voltage * amps = power. If you increase the total power capable of the battery, that means you can feed more power to the motors to higher RPMs. Basically, the less power your battery is capable of, the sooner your motor starts dropping off torque as speed picks up…

ahhh, so with a cell rated at 30A, would you set the current limits on the BMS or the VESC to push the battery harder than you would for a 15A cell?

You don’t have to but that’s the goal. The higher discharge batteries are so people can pull more power out of the same size pack.

That’s the one. It’s fugly but seriously capable.

Because one is made by flipsky, and one is not. Flipsky makes (and sells) things cheaper than other places.
