Default Some LiFePO4 Battery Testing Results Manual and Automated


Thanks for the data point. To compare apples to apples it would be interesting to test connected to a 12ohm load as I did - not that 12ohms (~1A) is somehow perfection.

Thanks, John OHM

Just a suggestion but you might want to look at the following.

Allows you to set discharge current and cut off voltage. Displays consumed mAh over discharge period.

You do have to calculate the cut off voltage per battery type X cells in series. There are many articles (and debates) on safe dishcharge cutoff voltages for various lithium batteries chemistries on line so I am not going to make a suggestion as to cut off voltage.

I just wanted to suggest the above tool as I find it useful. I fly very large scale R.C. helicopters which use rather large battery packs at high discharge currents and I find the above very useful for analyzing my packs.

The only reason for selecting 400 mA discharge is that is as much current as my little Imax RC battery charger can sink.

400mA vs 1 A is not quite apples/apples, agreed, but for LFP batteries it's going to be very close.
