Hah ya I think I'll do the same.
I don't need a light in there, the trunk is rarely used except hauling stuff to the track.

Them FEELS! I read about EarthX after I bought the Shorai. :bonk:

The BMS is built into the EarthX; it's the only lithium ion starter battery I've seen properly setup like that!

I found the supplier that manufactures the Shorai battery and they have optional hardware to add a BMS. But it's an additional circuit board that has to be integrated into the packaging; it's not something you can really buy on your own and bolt on to your battery. I might just order parts and build my own next time.

The EarthX and Shorai are not Lithium Ion but Lithium Iron Phosphate batteries. Quite different.

cheap led strip from kmart, auto zone, etc, and 2 spade connectors and you have an upgrade + lights that `virtually` can never drain your battery.

*eyeroll* Lithium Ion is a generic name covering all the lithium ion based battery chemistries. But thanks...

Ha. I had this happen once. Props to @quark for the low power bulb tips!

Anyone else kill their battery with the trunk?
 

Happened to me once. I'm really careful to confirm the trunk is closed now. I notice it closes completely easier now than when the car was new.

I open the trunk fairly often. I keep detailer spray in the back, as well as an umbrella and my sunshade. And I do use it for groceries or home depot runs.

I did replace the bulb for a brighter LED. Didn't even think about the low power aspect. Nice!

I'd just say hit the button and turn the key fob trunk opener off and have to use key to open the trunk. That would save your batt.

How about not closing the trunk like a little girl?

I don't think it is the trunk bulb that is draining the battery. with my headlight switch in AUTO mode and trunk open the headlights stayed on. They did not go out after a short interval when exiting the car as they normally do. I was parked in my garage and unloading packages from the trunk. I made a couple of trips and noticed that the headlights were still on..Once I shut the trunk the headlights went out shortly after..as they normally would.

I do not know if they would have stayed on or not if I had not closed the trunk. My guess is they would have.... its a convenience feature I assume....This may not happen if you park in the daylight..my garage is an under house garage and fairly shady even in daylight..the auto headlights do come on when I pull in to it.

I'm not sure if the running lights would act the same way if you parked in the daylight with headlight switch in AUTO and the trunk open...I going to see about that

Booooo.
