I’ve searched around and can’t seem to find anything specific to what I’m trying to do. I’m looking for information on the DC charger that keeps the 12 V battery charged up, or more specifically access to the DC charging itself.
i’m looking into using my own lithium battery pack for an ad on subwoofer and amplifier. I have a 4S2P headway lithium pack containing eight 38120 3.2v cells with busbars that I’d be using for my battery. Ideally, so that I don’t tank the primary 12 V battery, I would somehow tap into the DC charging capability to charge my lithium battery separately and have that be the source of power for the sub amp. I’m not planning on going crazy, I would probably target between 1000 to 1500 W for the amp. I’ll be using a battery management system to monitor and control charge.
I know there are third-party add-ons that have options for one or two 8 inch subwoofers that go in the storage holes in the back of the model Y along with an aftermarket amplifier to power them. This would just be a little bit larger scale, I plan on using the extra storage below the floor as an enclosure for the speaker, probably a 12 inch.
For anyone that has done a project like this on the scale, what have you run into as far as performance, affects on battery life, etc?
