Q: Could I put my own logo on the product i purchased?Ī: Yes, customers' logo can be printed by laser printing, transfer printing, silk printing and carving for free. All our clients, from home or abroad, are warmly welcome to visit us! It takes about 50 minutes from Kunshan to Shanghai Hongqiao International Airport. Q: Where is your factory located? How can I visit there?Ī: Our factory is located in Kunshan City next to Shanghai. Q: Are you manufacturer or trade Company?Ī: We are a premium manufacturer both in direct investment and joint ventures for Automotive Electrics. It is designed for situations where a battery charger or second charging source is used into the house battery. If either battery is receiving a charge the VSR will activate paralleling the two battery banks. It can protect your start battery from being drained by over loads on house battery.ģ) Dual sensing: It allows the device to sense the voltage of both batteries that it is connected between. When charging stops and voltage falls, the VSR automatically isolates the battery banks, ensuring that engine start batteries are kept fully charged.ġ) When the engine is started and the voltage of start battery reaches 13.3 volts, the VSR engages,allowing two battery banks (start and house) to be charged simultaneously.The indicator (LED) is on.Ģ) When the voltage of start battery drops below 12.8 volts (eg the engine is stopped), the VSR disengages, separats the batteries. When the voltage on the charged bank rises sufficiently, the VSR engages allowing the 2nd battery bank to charge. The Voltage Sensing Relay (VSR) allows the charging of a second battery bank from any single charging source. Why do you need a voltege sensitive relay? ![]() This 12V 140A Dual Battery kits will constantly scan the main battery voltage level for connection and charging of the auxiliary battery to the main battery for charging. 12V 140A Dual Battery Isolator for Marine UTV, ATVĪutoscien 12V 140A Dual Battery kits offers you an amazing unit which is automatic separation and connection of the main (starting) battery in parallel with auxiliary battery according to the level of voltage of the main battery.
