I have 4 batteries that are capable of providing a continuous 10 amps each. They will be connected in parallel to drive a motor controller with the intent on delivering 30 amps of continuous average power. It is desired to have each battery in a diode OR configuration such to prevent reverse current flow into the battery, damaging them.
Will a 4 battery diode OR circuit automatically handle load balancing between the 4 batteries? Someone briefly described it to me as working like this: The first battery will deliver a burst of 30 amp current, causing its voltage to drop, in which the diodes will change to enable the battery with the highest voltage, and the process repeats. He said this switching happens so quickly that it effectively balances the voltage across the batteries, causing all diodes to effectively be "ON," acting like batteries that are directly connected in parallel (except with a diode voltage drop).
Is this description generally correct? Are there any other concerns for doing this (IE, use schottky diodes for example).
The batteries are BB-2590/U
