Yes, since it’s the recharging in and of itself that cause the wear on the batterylife. It’s just that it is the motor that provides the charging current instead of the wall-charger.
Sorry for gravedigging 
If i understand this thread correctly, the only way to generate current to charge the battery is while breaking. This means, pushing the board in neutral mode doesn´t even charge the battery a bit, even if i do this for 10 km. So the only way to charge the battery on the road is to push very hard while braking with the remote or roll down a very long and steep hill breaking?
What if your using dual Vesc’s? Would you devide the current and set each Vesc at -6 amps battery regen max?

if i recall correctly it is not recommended that you push your board with out using the motor since it will fried a componenet in your vesc, i know i read it somewhere here
If the batteries aren’t connected

The discussion was whether or not your VESC/ESC will be damaged by riding with the board off due to the small amount of electricity created from the spinning motors. We never conclusively found out if it is/isn’t harmful for your system, but agreed that you would be fine as long as the board is on. My personal theory was that the current generated would be minuscule enough to not damage components even when the system is off.

vesc will turn on if connected to motor and they spin. if there are no batteries connected as well to send the energy too it will generate enough current to slam on the brakes if you’re lucky and coasting or ruin components if youre not. think the capacitors. read this on vedders forum and I’ve experienced the brake slam on.
so i guess coasting is regening as well. using the brakes without a battery attached is bad news though and quick death…although I got lucky there too

What if you disconnect the motor wires to push home, say if your battery runs too low. Would it damage the motors to spin if they are disconnected ?
Pretty sure it won’t damage anything, the current has nowhere to go.
I’m pretty sure as long as you have batteries connected and coasting your fine. Assuming they aren’t fully charged and you don’t go down a super steep hill that puts you over the erpm limit
If I have 2x4000 3s batteries in series can I charge at 8 amps?
How does regenerative braking work on a diy board?
whey you apply the brakes the energy of your momentum gets converted back to electrical by the motor, then chemical energy in the battery with roughly 30 percent efficiency. you can adjust on the vesc the amount
Does VESC monitor the actual battery charge? If the battery is full and you try to charge it with 4 Amps, it might damage it.
does it charge via the xt60 connectors?
I have the same question. But it would make sense to me to devide it, if you have a dual vesc.
Did you ever get an answer on your question? I’m wondering the same

As long as the connectors on the end of the phase wires don’t touch each other closing the circuit, there will be no resistance between the wire and the magnets. I believe it is safe to roll with the phase wires disconnected and secured so they don’t short out.

Thanks, but I ment your regen question. If -12a is set with single setup. Should it be -6 with dual setup?
Yes, but this is a personal preference, you have to try a few combinations to see what you like better
The truth is, any charge current that has sufficient braking force is already too much to the small battery’s that most of us use (3P) but since there is currently no alternative we have to live with it, since we brake for only a short period it may have little influence on the cycle life of the battery
That’s way boards like @Mellow have a integrated braking resistor, the excess energy goes there and is converted to heat
