I got this esc that I think does at least 200 battery amps:
Do I need a bms that will do 200 amps or can I discharge around the bms somehow?
Was going to get one of these.

Just get any basic Daly BMS and bypass discharge. Then set the proper battery values in Vesc Tool.
bypass discharge 100%
Ok as long as it can do the right amount in series good enough? And for charging do I need to keep under the max charge rate still?
What max voltage would u do with this esc Knowing will do high regen?
? ?? Whst voltage u think max I should do?
as long as u donât exceed 75v (also account for the voltage spike), then it will work
its recommended u donât go near what the bms is rated for, for example, a 20a charge current bms, u will charge at around 15a.
16s liion max
If I do 18s (lifepo4) can I use a 20s bms? Thereâs no 18s available
ohhh wait, u want lifepo4, there is also 18s version for it
The esk8 hub lord is having trouble picking up a BMS? 
I donât know if thatâs a compliment or not but Iâve never used one and always balanced off board.
I was just surprised that someone who stuck around this long havenât gone through the nitty gritty details of building a battery pack. No offense intended 
Ive made many batteries. I just bought 3000 cells earlier this summer. Iâve never done a bms though.
But as soon as I figure how to bypass the bms when discharging⌠I think Iâll be ready. ?
honestly, thatâs the easiest part, just two wires, one from negative, and one of the highest series positive, solder to connector for esc, then u have a bypass
So whatâs the difference from not bypassing?
So take a wire from the high positive cell and not from the bms?
not bypassing means ur current goes through the bms, and depending on the parameter of the bms, it has the ability to cut off current, which shuts down ur esc
I mean whatâs the difference in wiring?
If bypass I take the highest positive cell wire and not the bms wire to go to esc?
i think thatâs correct, i donât have the diagram on hand, but it should be correct
battery builder club people might be able to answer that
Positive and negative directly from pack to VESC, and only run the charge port through the BMS
I have masters degree in fine arts!
Lemme share my triptych.
This one is titled âNo Bypassâ.
This one is called âThe Bypassâ.
This one is ughhhâŚ
Awesome. Just what I needed thanks.
