Porsche OEM 12v 60ah Lifepo4 Power Module

Here's the deal with these batteries. Of course they are built with power lifepo4 cells and are in 4s configuration. Fully charged 14.6v and fully discharged 10v.

Now, the relay inside these batteries may shut off on their own. A common issue with them is the relay just shuts off when it's not actively being used. These batteries will take a charge and work but if the relay shuts off it will read 0v until you use the battery again in some cases.

If you added one of our 4s 300a lifepo4 BMS units to this battery it would be able to handle high continuous current and also pulse higher which would be perfect for a 12v power module for car audio or to use as a starter battery. We do not recommend using the battery with the original BMS.

First thing to do to open the case is if you get a battery with an L angle steel bracket just pry that off. It's glued on and pops right off. Next you want to pry off the sticker on the top of the 2 main terminals. See 3rd photo. Under that sticker there will be 2 bolts that need to be removed. Then, at your own risk, you can use a dremel and cut around the lid seam. You don't want to cut too deep of course. Once the lid is off you will have full access to the busbars and balance leads.

Dimensions are 11" x 7" x 8"
Weight is 28 lbs

To be clear, the value here is 4s 12v 60ah lifepo4 power cells in a case with busbars that can handle up to 250a continuous and up to 580 cold cranking amps. The BMS with relay installed in these may not work right but we know the cells inside are balanced and have good voltage. You don't have to add a 300a BMS. You can just add a 30a or 100a BMS and use this for other uses but if you want to use as a power module we do have the 300a 4s lifepo4 BMS units for a good price. The 30a 4s lifepo4 BMS units are very cheap and would work too. Just depends on how many amps you would need from this battery.

We did confirm each of these batteries take a charge.
