External circuit for GV-10 Series

Detection Circuit for GV-10 Solar Controller that work with our battery pack that has pcb/pcm installed.

• The GV-10 solar controller must see the presence of a battery (detect battery voltage) before it start charging. If the pcb/pcm is open (no battery output voltage), GV-10 solar controller will not charge the battery pack.
• Consist:
  
  • 1 x 9V regulator 511-L78L09ABZ
  • 1 x Schottky Diode 511-1N5817
• This circuit is design for the GV-10 solar controller to simulate there is a battery present so it can start charging (if our battery pack's pcb is open - due to low voltage or wrong polarity)
• Notes: You need this ONLY when you have PCB/PCM installed on the batteries. And it is for GV-10 Solar Controller ONLY
