They perform fairly well and the biggest plus is the price of 2.08€/piece same story for EVE 40P 2.09€/pc
Yes, thanks. I am ordering 12s i just miss it here.
Again price 165$ vs 265$ (I need 2pcs so 200$ is quite a lot diff.) , and flipsky motors are 95A so DV4s is going to be okey i hope. Honestly, I might take one DV6s and one DV4s.
Yes, I’ll take EVE 40P.
Please correct me if I say something stupid. I understand why you would bypass the bms and only use it for charging. But you only connect it as charging from the charger port. So the energy that flows from the VESC during recuperation/braking does not go through the bms. right?
Regen energy in esk8 is generally negligible in terms of needing protections for the battery in place. There are fringe circumstances where regen may prove to be significant enough to warrant protection for the battery, but i’d hazard a guess that 99.9% of esk8ers don’t need to worry about it.
But for interest’s sake, the thought experiment goes like this: you have your board wired so that regen current goes through the bms. You’re bombing a big hill down towards a busy intersection. You brake hard. The bms becomes overloaded and refuses to accept regen current. What happens next?
I tried using Neptune-Vesc BMS in circuit for my first build.
In theory it was supposed to see a duty cycle over UART, and apply different parameters for overvoltage protection.
In reality, it wasted a lot of my time before I gave up on the idea when it kept not working properly. It’s also a good way to over-voltage the ESC under braking and get a helpful notification on the phone that the battery has finished charging.
