Inline batteries off motor for alternator charging

[djmartin4582]

Can you run a lithium battery inline with your cranking battery (lead acid) to get a charge while running? I had a lithium die on me, and my remaining 125ah will run for electronics for a tournament day, but it was down to 37% at the end of the day and tournament days are my short days typically. I have a feeling it is not going to make it through a full summer day. Plus, I am having an issue with the 1 graph that is on the cranking battery shutting down every time I crank up, so I am going to have it move it off that battery adding more draw to my electronics battery.

what about a charge on the run box to charge batteries when moving?

To answer the question directly, yes.

Yandina Lithium Combiner is one way. When the voltage from the alternator to the lead acid starting battery is X, it will then parallel the lead acid starting battery with the lithium house battery. Both will get charged at the same time.

When the motor is turned off, and the alternator is no longer producing X voltage, the Combiner will disconnect the two batteries. You can use the house battery to exhaustion while being assured that the starting battery remains fully charged so as to start the motor.

I run a PHL Run & Gun charging system that charges my Lithium sonar battery from both Engine while running and off my Minnkota charger at night through my starting battery - https://bit.ly/RnGs

Been a great system so far, I think this fits what you are asking to do

THIS ^^^^^ Troll Bridge is the way to go !!!!
