Small&Portable 12V 24V 200Amp Mobile Dual Battery Isolator for Car RV

Product description: Model: BS-153

Working Principle
Dual battery isolator makes up an easy-to-install isolated charging system to charge your auxiliary battery without the risk of discharging your start battery.
A Dual battery isolator allows you to charge 2 or more different batteries from a single alternator safely, keeping the main
starting battery isolated from the second auxiliary battery.

Main Functions
1.Charge and discharge two batteries isolated 

When the engine starts and the alternator works, the voltage of the main battery rises to the connect voltage, the Dual Battery Isolator starts to connect the main and auxiliary batteries, allowing two batteries to be simultaneously charged in parallel; when the voltage of main battery drops and be lower than the disconnect volt, the Isolator will disconnect the two batteries to protect the main battery from discharging. This means that the auxiliary battery CANNOT discharge or draw power from your starting
battery.

2. Assist starting the engine

When the vehicle needs to start (if the voltage of main battery is too low), the battery isolator can supply current to the engine by forcibly connecting two batteries in parallel, and start the vehicle successfully.
