Anyone else kill their battery with the trunk?
 
Twice now I've walked out to my car, pressed the unlock button and nothing happened.. The first time was like a week after I got the car and I thought "oh shit it's broken already" and then after a ton of checking I noticed the trunk was JUST ever so slightly popped open. (It's surprising how hard it is to tell at a glance)
Well it just happened again, and this time with my fancy LiFePO battery :(
Here's to see how well they take getting COMPLETELY drained and recharged..

Debating either leaving the trunk disabled OR if I can get away with just removing the bulb from the trunk..

Why are you using a LiFePO battery?

Had that happen to me. Now I always make sure to check the trunk is securely closed before I walk away.

Because unlike other lightweight batteries it cranks like stock.
And it's baller.

I am popping it with the key, I almost never use the trunk which makes it double annoying when this happens :(
But then if I disable the trunk it will be annoying not being able to pop it when I do want to..

Any half assed lithium cell or package should have low voltage protection that does not let it actually drain below a set voltage. Typically when you reach that preset limit it will been the circuit to protect the cell(s). Id ask the manufacturer and also check it with a multimeter.

Had this happen to me also.

Swapped out the 5Watt light bulb (437mA) with a low power T10 LED (20mA).

With the LED and dash indicator the current draw is ~80mA, this will allow the light to be on for about 2 weeks with enough power left in the stock battery to start the car.

Shorai battery, I wish I had bought the earthX one since it HAS the over discharge AND charge controller ON the battery.
If this one is toast I will buy EarthX

Google is your friend. This one's on the autozone website. It's mine now. Get your own.

Got mine from a local electronics store.

The lowest power ones will be ~20mA, you can source from ebay

The cre LEDs will be brighter but consume more power ~80mA

Wait, I didn't read closely enough. If I get the 20mA bulb I can leave my trunk open for 2 months? Damn it!

You will get about 10 days with that LED, (stock battery down to 30% capacity). Much better than stock bulb (totally dead in 4.5 days)

Yes:mad0260:

But I just took the bulb out and crushed it

With the Shorai charger it recovered quickly

Lol
