No; only Ackmaniac firmware
You’ll basically need a CV/CC DC-DC converter on your external pack that acts as a charger for the other pack, so you just connect it to the fused charge port on your board.
It seems too dangerous to try to match levels every time you plug them together.
If it was a permanent arrangement, I would match the levels and connect them in parallel… ONCE.

I would put a fuse on the charge port

Connect the balance wires to the negative sides not the positive ones.
Slow down if you don’t want fires.

when you block someone and someone quotes them. is the quote also hidden?

air hammer=handheld jackhammer essentially. those (the stainless pair) seem to be part of a universal chisel/driver set. they originally came with a handle you could pop them into

Log out and see the thread? Or even simpler, copy/paste in a incognito tab
Whats going to happen to me if i use a gear ratio of 1:1 (16t/16t) Would i explode? calculator says it would get me 59mph

You will have a very, very low amount of torque. Probably take ten minutes to reach top speed from a stop

More serious question. Is there a part of the forum dedicated to finding people to ride with in your area ?

i think (but i don’t know) that your hubs use ntc thermistors
the esc applies a current across the thermistor’s two terminals, and measures the voltage drop. the thermistor’s resistance falls as the temperature rises (hence the term ntc). the rate at which the resistance falls with respect to temperature is the so called beta coefficient,
it’s not important to understand this formula, just know that adjusting these beta values in the vesc firmware can help you either:
- calibrate the vesc’s motor temperature measurements so that it more accurately reflects the actual motor temperature, or
- calibrate the vesc’s motor temperature measurements so that the 120° measurement better corresponds to the upper range of your motor temperature
the default beta value in the vesc firmware is 3380 kelvin. a sane range of beta values is probably 3000 to 5000. in vesc firmware version 3.28 and up this value is user configurable using vesc-tool, the setting field is simply called “beta value for motor thermistor”. in vesc firmware prior to 3.28, the beta value can be changed in #define NTC_TEMP_MOTOR(), but you’ll have to compile the binaries on your own after fucking with the source code.
i’m sorry for the late reply. i haven’t been more helpful simply because a little knowledge can be dangerous. also, i think newbies should stick to the ackmaniac fork, in which the ntc beta value isn’t easily user configurable in vesc-tool. not everyone shares this view
but, i love the smell of urethane burning early in the morning, so i’m happy to do our lord sk8tan’s bidding and point you in the direction of hell
all the best my friend

well he did misguide himself to cutting the wrong sensor wire. 
but since we seem to be about giving enough rope to hang oneself with multiple times…
the firmware variant: VESC_default_no_hw_limits.bin will eliminate that pesky 120c limit. along with other limits that you probably need to set reasonably.

dude could even have set his thermistor to some really wacky out of scale readings so it would be impossible to reach thermal limits…
but dood did what he did, and then took it personal when I laughed at his ineptitude…
I can’t see dude and I don’t care to…
kook out…
Would it be possible for a Canadian (me) to buy batteries off a vendor that only deals in the USA, have them shipped to an American (you) and have them forward it to me? Is that even viable?
Context: I wanna buy from jehu

@Flasher I’ve had some Canadians treat me really right on multiple occasions. If you’ve got a way to provide the label to re-ship I’d be glad to help you out and pay it forward. Seems expensive, though.
