YET ANOTHER BURNED SCHULZE
:)

I burned 2 Uforce-75 and a Future 18.97 .
Sure, loose contacts was the first Schulze reason for the first burning.
Nothing more false ... They say that loose contacts on the battery side
make resistance and this get the controller in flames.
Even if it was, here we have a competence problem: if a motor side connector
was loose, I could believe them, having a resistence phase doesn't help the
esc understanding impedance and rotor position; but the ones from battery
side ? This goes oput from my understanding.

The second Uforce (burned after a week from the first one) was repaired
in warranty, but they say me I used it with too volts for a 6600kv motor.
True I used a 3s pack to see if the controller was still programmable.
I did not throtle it, and they said that it burned due to the higher 3S tension
used with that high kw motor. Well not true but they passed it by waranty.

The future was burned with a feigao 380. Unbelievable .... a motor with less
than 500 watt burned a 1600 watt capable esc ... and connectors were all right.
Burned with a feigao (that I still use) and It did not burn with a plettenberg ...

So I closed too with their ESC.

But let me say they charger and balancer technology is really good. They have
an old design, and they are cryptical to understand and to use, but the do their
job in a really really good way. The Lipo balancer is wonderful.
Anyway neither the chargers, neither the balancer have a polarity inversion
protection, and the reason is that in their point of view it does not make sense:
if you invert polarity you are not enaugh coompetent to buy and use their
products, with a professional and warned use is a top reliable product.

My 2 cents about Schulze.
Ciao,
Daniele
