RE: 3's & 500 watts

You have 4amp hours. You will be demanding 45amps. 4/45= 0.0888889 of an hour. Multiply 0.089 by 60mins and you 0.089 hours is 5.3minutes. 5.3 minutes is 5mins and 20sec.

Given that you cannot use...

RE: What does this mean?

I would say not. Your power supply can supply 12vx1.5= 18watts. Call it 15 due to heat loss.

You are asking for 9.6v x3a= 28.8watts.

With 15watts charging a 9.6v battery you will only manage...

RE: Battery charging help lipo

Can you cycle the lipo with that charger? Alternatively use the lipo gently, take it down to say 3.5V then try balance charging. See if that is an easy fix"

RE: Storage of Lipo / size

RE: can someone explain lipo to me ?

Erm most of the decent lipo chargers are NOT limited to 50w. In fact almost the opposite is true. I.e there are hundreds of sub 50w inaccurate chargers. Now most chargers over 500w are...

RE: series or parrallel?

Not sure of the question. Connect the batteries so that the voltage x kv of motor equals approx 25-30k revs. I beleive selecting the best prop, balance and trim is more of an art.

RE: NiMH - Trickle

It is not a big problem but it is a problem. I believe it can accelertate the degregation of the pack. Also if you have a small pack the "trickle" charge might be relatively more than a trickle!

RE: Charged battery acting dead

It may be that the peak sensitivity of the charger is detecting a full charge when it is not. The first forming charge should be done by a dumb charger.

Basically divide the capacity, 5000mah, by...
