Hi Nick,

We have a number of battery gauging products that support 1-2 cells:

We also have a couple of protector devices for 1 cell products that may be interesting to you:

Hey Siddharth,

All those IC's are for Li-ion and Li-Poly, none will work with LiFePO4. I am looking for a single cell protector that has an overvolt cutoff around 3.6v, not 4.2v. The BQ78350 does this, but only for a minimum of 3 cells. I just need a single cell protector

Very best,

-Nick
