Description

WARNING Overvoltage-Reverse voltage protection with PTC and diode, Overcurrent Protection with PTC U2-U3. Overdischarge protection with microcontoller. Wrong setting may cause Injury or Overheating. Overheating + Battery = Acidic gas + Fire + Expolosion. Only for indoor and well ventilated areas. Produce at your Own Risk

12 to 15 volt step up converter,12V lead acid battery charger, output voltage keeper. All circuits can be baypass by solder trace. Keeper circuit has precharge of capacitor and shocky dyode for discarge. Relay can be turned on by Vin or Vout step up(V15). Step up can be enabled or disabled, charge circuit can be isolated from power, output and feedback. Vout and V5 can be connected to VIN o V15 rail. Any current gain could be make changing polarizing resistors on NPN and PNP transistor. To produce V15 steady 50V change D1. MOSFET Disconnect battery from load and does not protect during charging. To change protecntion profiles change PTCs.
