This lot is generally related to vehicles. Disclosed is a system to stabilize voltage load of a vehicle battery so that battery voltage is stable when the vehicle engine is switched ON. The system is using a voltage boost module, a microcontroller connected to the voltage boost module, the vehicle computer and a bypass module in parallel to the voltage boost module. The voltage boost module supplies a boosted voltage when voltage drop is detected and the bypass module supplies normal voltage till the voltage is stable. The technology may be implemented in vehicles, automobile batteries, vehicle battery, etc.
