this is really good video and it explains how parallel charging works really well.
I haven’t seen the M5Stack before - looks quite promising and expandable. Have you used them before?
Nope, but up until less than 2 years ago, my day job for the 17 years before that was analyst programmer, so I won’t be completely useless.
I’m going to re-flash this one to run Micropython on baremetal though, so won’t be using the pre-installed Arduino platform.
Check out these pics, looks very promising and capable. Dual core too.
Presumably its for the esc? what exactly is it and whats for?
Its a modular microprocessor with WiFi, BT, 9-axis accelerometer, buttons and a screen with I/O ports to control hardware peripherals.
Initially I’ll use it between RX and ESC to control PWM, enabling different throttle/braking curves and modes. Then more capabilities later.
Does this mean that you can alter the amount of current that goes back into the battery, when braking, depending on the stage of your on-board battery?
No, it wouldn’t replace the capability of the BMS, rather add some to the RX, and then some of its own via other sensors. It’ll only be used to change the signal to the ESCs, later with input from optical and accelerometer sensors.
Be careful with APS 6384 200kV both of them got loose magnets within a 2 weeks
You mean, those spensive chinese motors ‘manufactured’ in England by a renown british electric motor company!
Launch control, boost when heading up hills, etc
Mostly limits and controls, boost can be done by the user, not sure I’d want to make the decision on when to boost, much more comfortable with limiting too much power though.
