Using a quality lead acid battery is the better alternative.
Hey guys, I am looking at building a 16ah headway lithium battery to put in trunk as primary battery for audio system. My other battery would be lead acid to power car electrical.
If I have a charge controller on lithium, how should I connect the two batteries?
Would an isolator work? Or would I need to use a separator? I understand mixing battery types is generally recommended against. I also realize lithium has higher nominal voltage than lead acid.
If there is a better alternative than using lithium in trunk, I'm open to all recommendations.
You really should use a battery management module with these. Yes; they are more robust than other lithium chemistries from a safety point of view, but there's other concerns as well.
Without a charge controller, you are likely going to exceed the max charging rate and end voltage on the cells as well as put excess stress on your alternator. Also, I think these are raw cells, without any internal voltage cutoff chips. The result will be reduced cell lifespan; and potentially immediate cell failure upon exceeding the lower discharge limits.
Well, if you're carrying a load of fertilizer and diesel fuel... I guess that's one way to get a car that goes boom!Timothy McVeigh says
yeah you can research them .... specs appear accurate. they are used in industrial applications.If that page is accurate; that's one monster of a cell.
stock alternator?Not recommended, I would suggest to use AGM and have isolator in between if possible depending on what kind of battery you will use. If you go with headway cells, than you be fine.
I ran AGM with lithium side by side without isolator, and now I have AGM with Headway lithium love the extra power!
Safest headway batteries, also they provide power for days! My voltage doesn’t drop below 14.2 volts with music or without!
