The easiest way to install a secondary battery in a car, the best solution for the secondary battery installation

The easiest way to install a secondary battery in a car is to buy a smart three-stage car battery charger and place it in a small place in front of the passenger, then connect the secondary battery and place it under the passenger seat, and connect the battery’s power cord to the cab. It's okay. When you don’t want to use it, you can disassemble it in just two minutes and restore it to its original state, which will not be so troublesome.

The best solution for secondary battery installation:

1. Connect the positive electrode of the original car battery tofusebox;

2,Fuse boxThe wiring goes through the engine compartment into the cockpit and connects to the positive pole of the air switch or double electric isolator;

3. Connect the negative pole of the air switch or double electric isolator to the positive pole of the auxiliary battery;

4. Connect it from the negative terminal of the auxiliary battery, and find a nearby location to ground the iron, which is the grounding wire.

All of the above are connected with cables. If you are using a double electric isolator, you must lead a 14v thin wire connection from the ACC door of the cockpit or engine room as the working signal line of the double electric isolator.

Generally speaking, the cars that need to install a secondary battery are some modified off-road vehicles. Off-road vehicles need to be equipped with winches, spotlights, etc., which are very electricity-intensive, so a secondary battery needs to be installed. Because the installation of the auxiliary battery involves the circuit of the car, it needs to be installed in a very professional organization. The owner must not install it on his own, otherwise it will increase the risk of spontaneous combustion of the car.
