    I recently replaced my dead battery with a brand new oem toyota battery. Giving it some thought after reading
    about now heat is the enemy on these and will shorten its life some. Since my car has no real choice of being garaged or out of the sun and after paying 3.6k for this i want to see if there is any way i can help keep it healthy as much as possible. So if you can see from the photos this is what i came up with. Now before i go any further with this battery idea i really want feedback from anyone at all. I want to know if this might be a good or a bad idea asap so i don't cause any problems or maybe just make adjustments if i'm on the right track.
    Thank you for your thoughts in advance.
    p/s If this is good then hopefully you might concider this. If not then we will soon find out why or possibly how to improve on this. Rechargable Batteries really don't like heat. gee you think? :)

    Don’t have to do anything, this new battery will most likely outlast the other parts of your car, so you should just leave it alone

    If you were going to do something like that you're going to keep the heat in the battery more it'll radiate outwards and away from the battery just do the sheet metal but once you put that blanket on it where is it going to go You're depending upon just the fan only to suck out ambient temperature plus heat of the battery correct? And like others have said these batteries make about 10 years of good use that's probably going to outlast the car unless you're me.

    i guess i would measure the temp inside the battery and out, to determine which way you want the heat to flow.
    are you using window shades?

    And the winter time I don't really run the heat so it's getting pretty cold air circulated around the battery when the fans on If I thought it would make a big bunch of difference I could rig up a larger CFM fan pretty easily 12 volt and all that but the regular unit is clean seems to do a fine job in the summertime I keep the air in the cabin ice cold so the air that's getting sucked to the battery is quite cool and in the winter time I really don't run the heat unless it is near zero or just to clear the windows and then down to low vent towards the floor I'm in the southeast United States so seeing freezing temps is not often.

    nc and la are probably fairly similar climates too, although i have read that gen 3 batteries are less robust than gen 2?

    THANKS FOR YOUR INPUT! YOU ARE PROBABLY RIGHT TOO. JUST LEAVE IT ALONE.

    YEAH, I PROBABLY JUST OVER THINKED THIS IDEA AND WHY I POSTED SO I CAN BE CHECKED ON IT. THANKS

    IT WAS JUST A THOUGHT. BUT THANKS FOR YOUR INPUT!

    I WILL BE TINTING THE WINDOWS BUT THAT ABOUT IT. THANKS FOR THE INPUT.

    I SEE WHAT YOUR SAYING. OK JUST AN IDEA. YOUR WAY WOULD BE BETTER WITH A BIGGER FAN BUT NO, ITS ALL COMING OFF. THAT FAN IS TOO SMALL AND PROBABLY WON'T REALLY DO MUCH. yOU GUYS ARE ALL GREAT FEEDBACK HELP!

    Some guy with a popular referral code tried this already with micro fans that moves 4 cfm, no luck. At least you have a larger fan, still won’t draw any air from the intake end. You’re better off with reflectix window cut out with a flat stock up the middle.

    Good for you! Hope it all works out. I was just curious about if what i did would actually make any difference. I don't think it really did.

    I still have the mod in place but not being used at the moment.

    Im planning on connecting it to the solar roof panel from the solar controller usb.

    That way I will not have to charge any power bank or mess with it anymore.

    As for the fans, they are not causing any restrictions while not being used.

    Was planning on reconnecting it back when I connect the solar controller again.

    Been testing out the lithium v2 and watching temps as is before I connect the fan mod again.

    Hope the OP keeps this updated with his testing.

    I am also working on a A/C mod to direct the HVAC air to the intake fan to keep the temp in the sweet spot.
