2021 Ford F150 Super crew

Recommended Posts

Hello all!


I am looking for some help with my system.  Here is a little back story.


I have a 2021 Ford F150 Supercrew with 4 8 inch Digital design subs under the back seat.  I am only getting roughly 12.4 volts to my amps due to Ford's BMS (battery management system).  I have not seen any work arounds or found any information about how to solve this situations.  Here is the ask....


Are there lithium banks out there that i can install that will run at 14 ish volts without having an alternator charge them all the time?  I was wanting to run a bank on its own to my system and possibly charge it from the DC to AC convertor i have installed.  I am willing to put this bank in my bed under the bed cover.  I currently have 2/0 wire ran to the main SMD block from the main battery.  I could swap out the small invertor for a larger one to charge my bank.  


Is this even remotely possible?  Just tired of seeing my digital designs m4000 sit at 12 volts and not put out any power.
