Sxx v2 stock spec esc problem

[jampat2004]

Just received today brand new sxx ss v2 for my supastox bought this for the 1 cell function.On connecting up to fully charged 1 cell lipo nothing happened no lights on nothing,thought this a bit odd,tried 2 cell lipo works perfect what is going on?
Have read instructions back to back.
I'm no novice with lrp esc have a sxx v1 in my 4wd buggy and sxx v2 in my 2 wd buggy,have connected 1 cell lipo to both buggy speedos and they work fine, what is wrong with my new speedo.
Hope someone can help with this.
Thanks

Double check your soldering son

It's more than Likly in 2s mode
Also I found with mine you need to disable lipo cut of

Hi
ive read somewhere, that the new logical chip hadn´t got a powerpunch. The punch makes the 3,7V from the lipo to 6V for the esc. Now you had to use an extern powersuply.

Sorry for the bad english I hope you can understand it

A new logic board is available so it is like the Flow.

Read the instructions - If it says it has a booster, it should work. If it says the BEC is linear, it needs an external booster/battery.

That would make sense with the info I got about the Nosram I got that failed out of the box. The only replacement was a "v3" one that had no booster, like a flow.

Thanks chaps for replays, but said esc has gone back to supplier.
