Capacity testing 18650 LFP cells

[jonescg]

Hi all,
I need to capacity test about 100 LFP cells, and DCIR. I have some 4-cell testers but they are designed specifically for Li-ion chemistries like Li-NMC and Li-Co and take the cells up to 4.2 V. Does anyone know of a good option for LFP cells at 3.2 V nominal, and 3.65 V max?

???? Not sure what your question is. A good option for LFP cells or a good option for LPF cell testers?

I want one of these:

But with programmable voltage settings like 2.65 V to 3.65 V

Plenty of universal battery chargers around.

However I see what you mean about programmable.....might have to go with something like this....or similar and settle for the internal settings.

Edit: Looking at page 6 of this one, it looks like you could program it to what you want. I have never used one of these, but it looks like if would fit your specs.
