#Smart battery isolator 300 amp full

It is used to isolate the primary and auxiliary batteries in a system while the auxiliary battery is being charged due to dual sensing technology. Not to mention, it is microprocessor controlled, that is why, our Dual Battery isolator is designed to protect the start battery from uncontrolled discharge while allowing the auxiliary battery supply charge to non-essential loads at the same time. Smart Start (SBI) battery isolators make you stay out of the road for longer rides because it helps prevent your secondary battery from draining the main one. I don't intend to leave the lights on but since I will be taking this to remote areas I don't want to take any chances and get stuck with a dead starting battery.Application: 4Г—4, Sedan, ATVs, UTVs, Side by Side, UTV, Personal Watercraft, Snowmobile, Street Bike, Cruiser/ Touring, ATV Once connected feel the wires and see if any are getting to hot for the first 30 seconds.ok even simpler. Once the jaws are tightly clamped on will make good connection and the sparks will quit flying. So open the jaws fully, and be quick about it. Just beware when you connect to the Isolator, do so very quickly because you will draw a little fire. Disconnect the SLI Battery FIRST, then the other end and drive away. Walk away for 10 minutes, start the vehicle. Then connect the other end to the Isolator terminal with the House Battery. Connect one end to the SLI battery Positive Term Post first, ALWAYS FIRST.

How would you jump a car with a dead battery? Would you buy switches and relays and hard wire to jump a car? Getting any ideas yet?ДЄll you need is one Jumper Cable about 1 to 3 foot long. Not that difficult.ДЇirst you DO NOT want to automate it using a relay or switch of any kind. You are in the right ballpark, but in the wrong section and way over thinking it. if I left my lights on and drained the starting battery down to dead what might be a time frame on charging the starting battery like this? It is a good battery AGM Diehard Since the isolator needs 12v to make the connection between front and rear batteries then I need to run a small 12 AGW from the rear battery bank to a small toggle switch that when flipped turns on the isolator and makes the connection between the two battery banks.ДЄnd. Some can do it, but poorly at best.OK then, so I take it the smart way to do this instead of installing an expensive battery switch with large wire and actually bypassing the isolator would be to add a small toggle switch that controls the isolator? Keep in mind a Deep Cycle battery is not made to crank an engine. What you can do is bypass the Isolator and have the House battery charge the SLI battery. There is no wire large enough to carry 12 volts any distance. You cannot remotely set a battery away from the engine. There is a reason SLI batteries are installed in the engine compartment close to the engine with large wires.

This will only work if the starting battery is dead because it was discharged too far rather than because it has failed chemically or mechanically. The current would then come mostly from the partially recharged starting battery.

Instead of counting on the house battery to deliver the full current to the starter, a more practical solution would be to close the switch and let the house battery charge the starting battery for a few minutes and then try to start the engine. It will be difficult and expensive to run a wire that size through the vehicle, but fortunately you do not have to do that. Plugging in the numbers to figure 20 feet of wire (one way, since we hope that the ground connection through the frame will be good enough to give a low voltage drop) and 200A and a voltage drop of 4V, we get a required size of #3/0 copper. If you can estimate the current drain of the starter motor and the length of the wire you can use tables or calculators to determine the needed wire size. To get significant help in supplying starting current though, you would need to keep the voltage drop on the wire down to 4V or less. is this even doable? What would the AWG of the line running to the rear battery bank have to be to account for a short burst of many amps for 1 second? It's a long line like 15 feet.For the short time of a couple of seconds you can overload a wire significantly beyond its normal carrying capacity, since it will take some time to heat it up to the point where the insulation will be damaged.
