NEC 12v35i HP CAN bus Lifepo4 13.2v 35ah 462wh - POWER
These are very high quality lifepo4 batteries that can also handle up to 210a continuous charge and discharge rates. This is a power lifepo4 module that would be a good candidate for car audio as well. The specs are in the photos. This is the HP version (high power).
Bolts are included.
We tested each battery and you will get a printout of the test report which shows capacity and curve chart. All of these batteries tested between 90-99.99% capacity so they likely have only been cycled a few times.
We have a lot of customers that use these for car audio. A good rule of thumb would be 2000w for each battery for car audio usage. If you have a 5000w amplifier then you would want to parallel 3 of these together and make sure the busbars are thick enough to handle the current.
