   * the vagaries of voltage sag across the system may result in the various charging sources seeing slightly different voltages and therefore contributing in unpredictable ways.((probably a non-issue as long as the bank is getting properly charged))  Voltage Sense wires can help with this issue.     * the vagaries of voltage sag across the system may result in the various charging sources seeing slightly different voltages and therefore contributing in unpredictable ways.((probably a non-issue as long as the bank is getting properly charged))  Voltage Sense wires can help with this issue.  
-  * Multiple controllers set up to trigger Float from endAmps((trailing amps)) may enter float early since they are providing only some of the charging current.+  * Multiple non-communicating controllers set up to trigger Float from endAmps((trailing amps)) may enter float early since they are providing only some of the charging current.
   * Multiple sources may inadvertently exceed the bank's recommended charging current, or your preferred current.  Example:  a lithium battery wants 50A max but each charging source can make 30A.  This might result in overcurrent (60A) during Bulk.     * Multiple sources may inadvertently exceed the bank's recommended charging current, or your preferred current.  Example:  a lithium battery wants 50A max but each charging source can make 30A.  This might result in overcurrent (60A) during Bulk.
