Other Parts Discussed in Thread: BQSTUDIO

I try to select the chemistry ID in the list of "Chemistry Programming" in bqStudio.

But I find that same cell have different Chemistry ID.

For example,

SDI ICR18650-26H has ID 2077 and 0227

SDI ICR18650-32A has ID 3236, 3225,3455 and 3606

Which one should I use?

Thank you~

Hi Sean,

It may just be an accident that there are multiple Chem IDs for the same battery. It shouldn't matter which one you pick for each battery as long as the capacity and voltage match those which are specified on the battery.

Hi Sam,

Thank your!
But how about SDI ICR18650-32A given the ID=3236
In description column: LiMn2O4(Co,Ni)/carbon,4.35V, -10C
"-10C" ? Is it specially fined tune for low temperature application ?

Yes, the Chem ID that mentions "-10C" was characterized at that temperature. Unless you are planning to operate your device at that temperature I would choose one of the other Chem IDs that match your battery.
