New YGE 90lv V2

[trexpro]

Hi Guys,

I want to know if the YGE 90lv V2 with the new improved bec of 8 amp's continuous and 18 amp's peak has a cut-through protection (which means the battery voltage won’t get through to the receiver if the BEC is accidentally damaged)?

Thanks

Does anyone know this?

I have send YGE a email but they don't answer

Not to highjack the thread but I haven't seen these anywhere yet,we're can I get one in the states

how do you tell V2 from V1

what about the v 4 ? is there any difference the v 4 and v2

my understanding the old esc is upto v4 - 6A bec 12A peek ; backflow protection
the new esc that ppl call v2 is actually v5 - 8A bec 18A peek ; no backflow protection

[ragge1]

new pics on the difference of the old v1 and the new v2

old with the 6A BEC



new V2 with the 8A BEC

What can be done to protect the electronics in the event of a failure?
Thanks

Ragge1 - thanks taking a look...

Hmm. .... ragge1 missed that when reading manual! How would these be fitted?

using the optiBEC guard ; manual


using the diode , borrowed a pic from a helifreaker from the Swedish forum

Thanks Ragge1, the diode was what I was unsure off, but this helps a lot,

[helirifick]

So we are trying to limit the full current from flowing from the flight packs to the RX/FBL/servos in the event of a BEC failure??

That Opti BEC Guard will clamp anything over 10 V and then shutdown. I am thinking of getting it, but it's $40 and they recommend 1 per master and 1 per slave power output from the BEC -- so that's $80 per standalone BEC or ESC/BEC .


Ragge1, how does this Schottky diode rectifier that you posted work & how does it prevent massive current from the main battery from going through in event of BEC failure vs. allowing regular 5A 8.4V per master / slave connection out of the YGE90LV v2? I looked at the spec sheet for that thing from International Rectifiers, but can't yet make sense of it.

thanks

The new Version (V2)

• BEC 8A duration. 18A peak
• 5,7V /7,4V/8V adjustable by jumpers
• The BEC is short circuit proof and temperature supervised
• Two Receiver cables (Masters/Slave)
• RPM output for VStabi

Any idea when these v2's will be available in the states?

I went ahead and ordered a v1 90lv with power bec from mikado usa and I just got it in the mail. I was pleasantly surprised when I opened the box and saw v2 8A/18A bec. If you are looking for the v2, order from Mikado USA. They have them.
