2 questions - PCM Controlled Smart Charging System.

Hi All.

Does anyone know if a 2000 GT has a BMS? I was looking at a 11.5Lb lithium battery. --> https://shop.antigravitybatteries.com/products/starter-batteries/automotive/rs-30/

but it doesn't work with Mustangs that have a BMS.


Also does anyone know the alternator voltage output before and after a underdrive pulley install? The battery above needs to see 13.8v to 14.6v to operate and I was wondering if a underdrive alternator pulley would be below that limit.

Thanks for your help in advance!

It should not have one. 13.8is a pretty high minimum output for a car with underdrive pulleys, but it would be easy to check, start the car and check battery voltage, then turn on all your accessories (blower high, wipers high, all lights, stereo, etc...) and check the voltage again.

Yes that was what I was thinking that it doesn't have any BMS. I dont have the underdrive pulleys but was thinking I would get some but that was before I though about how to lighten up the front end and found that super light battery.

Thanks for you help.
