Bro, don’t sell yourself short. You’ve got so many more resources available to you if you’d put in the tiniest bit of effort.

I’ll throw you a bone on this one. First google search result.

If you really want to know the specific differences, pull up both the product pages and use those eyes your mother gave you.

looking to buy Flipsky’s Dual FSESC6.6 Plus for 12s EMTB setup

do you have any thoughts about it? pros/cons?

#15241

Pros : if it works, you are lucky that it works. No guarantee for how long.

con : its flipsky
Bad QC, probably no warranty or support.

Can’t help you much but i see a red led flashing there, coincidentally on the side the motor doesn’t spin

#15244

Make sure that flashing red light is not on the ESC. It looks like it might be on a radio receiver, which is okay I guess

I think those remotes have UART and PWM (“PPM”) modes of operation. I haven’t used one. How do you have it connected?

Connect the remote as PWM (“PPM”)

Turn on the “real time app” on the right side in the VESC Tool

Make sure you can see the pulselengths in real time. That’s probably the first step to checking that the ESC sees your radio input.

#15245

make sure you are connected (bottom right)

The “From VESC” and “VESC Tool” should be displaying a realtime graph that you can move with the remote

Are the C ratings for Zippy lipos somewhat accurate or grossly exaggerated?

#15247

Thanks Bill!. I’ll check out those links. Appreciate it =)

#15248

Any harm in leaving your charger plugged in after charging is completed?

#15249

Nope, I often recommend it as this is when many BMS do their balance work.

These would be cool for a last mile penny board for college students, but I think its more suited to larger FPV vehicles and stuff

I am looking at using @eboosted 's 12s BMS but it states that he only builds them for charge and not for discharge because it isnt safe.
Mentions power loss from braking on a full battery which i get but how is that discharge? Thought that was charging. And because you cant overcharge so it goes to heat at that point. So does this mean that it doesn’t support regen braking?

#15253

Hmm gotcha, I asked because it looks very similar to the mini FOC and mini FOC plus. Just arranged in a circle vs square

#15254

I can’t imagine it would go above 20A batt without some active cooling. An FPV flying in the air at 100km/hr will be able to be used at slightly higher power

#15255

Is this due to the small size? If I’m not wrong, it’s bigger than the miniFOC and miniFOC plus

#15256

I think you miss something. Bms is wired for charge only, indeed.
From the charge plug, through bms, to battery. Charging.

For the esc, the wire comes directly from the battery, with no stops except for the antispark/loopkey. The esc draws power safely like this, and when you brake, sends that extra energy back into the battery. If the path to battery is interrupted when you brake, the esc explodes. And a bms tends to cut the power in the nastiest situations

#15257

Ok so what does he mean that he doesn’t build them for discharge then? do some do that? and what does discharge actually mean I guess.
not knowing much I imagine it safely takes it down to a certain level for storage.

#15258

And what would cause an interruption to the battery path?
