My question was: If in direct drive I can barely get 2.7A how the hell can a 8*7135 stay in regulation?
But you answered my question: I need copper braid and bigger wires. Maybe that the transistor used for PWM has a high RDSon too… I don’t know.
About my battery, I use Sanyo 2.6Ah protected. The internal resistance of the cell is less than 100mOhms.
I just added braided wires on my springs… The result is… Well, I let you read this.
