As the title says can you squeeze a second battery on the V6 twin Turbo Limited F150?

Not in the engine bay. Maybe if you fabricated a box and reroute the wires to the bed of the truck or inside the cab/under the seat?

If you are referring to a second 12v battery in a Powerboost, I am not sure why there would be a need.

The 12v only starts the truck and powers minimum electronics while truck is off. I believe the hybrid battery runs everything once the truck is running or ready to drive.

Did you end up looking into this further or buying the second battery?

I installed a 40ah Lpf behind the seat. Removed the jack and auxiliary battery under rear passenger seat. The pos and neg leads just connected to the new battery. 5100 seeies fits nice. I have a powerboost with 7.2k. Deleted bms and I charge at 14.6v all the time.

James, with the more powerful battery, are you seeing added time in electric driving mode?

Unfortunately not. The electric motor in the transmission operates on 48v I believe. I am looking into adding capacity to that system however I haven’t figured out the chemistry of lithium or the cpu algorithm for it yet.

I'm planning to get the Decked drawers (https://decked.com/products/decked-ford-f-150?variant=31141615175&year=2021) install a dual battery system and wire 4 spare batteries in parallel in the corner storage wells as my secondary battery.

Point being, you don't have to add 1 big battery. You can add multiple smaller batteries wired in parallel (properly fused of course) to replicate one big battery if space is an obstacle.

I'll be adding lots of extra 360° lighting, two-way radios, etc... and I want plenty of on-demand power.

Since I wanted a "Truck" instead of a "Land Yacht" the on-board generator was one of the (many) options I was forced to give up.

You might want to look at some of the youtube video's for trawlers and catamarans. Owners have much experience in running the house from 48v systems, recharged with solar, wind , and regeneration hydro props. A lot of the sailboats and catamarans have replaced their 29-75hp diesel engines with electric motors.

My 2008 Escape Hybrid has a 360-volt battery. This truck has a 48-volt to do the same work, in a vehicle twice as heavy?

based on this the truck has 3 batteries (Starting, aux and the power boost battery under the bed)?

I’ve added a fridge and was looking to install a house battery and run it on 12v vs 120ac and it sounds like Aux battery upgrade is way to go. Thanks for the info

Hi James - What do you mean by deleting BMS? Did you remove the BMS that came with your lifePo4 battery or did you remove the BMS that is attached to the negative post of the starter battery? And - why remove that BMS?

Do you have your truck yet? ?
