Out with the dogs atm, but if you then read on, I explain why they can be used.
I'll do a full reply when I'm home, purely as my reynauds is acting up just replying this.
But this is the basic reason.
The 350s, can you tell me the actual manufacturer of them? And don't say Efest, if you do, I will cry. Do you know the exact spec sheet as well? And how many amps they can pull whilst pulsing, and how they sag for both current and voltage when under load?
If you do, then fuck it, use 350s. But until you Know all that info, don't.
I know the 30 amps can do it, as I've read the spec sheet, tested them in over 10 mechanical mods with low builds to account for different levels of voltage drop, and have read the spec sheets published by the manufacturer.
However, I do also add a notice saying, in effect "on your head be it". Ie, I don't actually advise doing it, but it is possible to do.
Toodle pip.
