Testing 20k Lifepo4 cells
#1
I keep coming up with these little LiFePo4 cells, have enough to keep me busy next decade now ... finding there are not many test options for them. I see most people seem to use the Opus, why is the Nitecore i8 not more popular? holds twice as many cells for almost same price... any other options for higher volume?

Hmmm, some review I saw before listed capacity testing, but now I see it has no discharge function. Yes I saw your setup, subbed to your videos, very nice. So I guess I will take the Opus as the optimal setup for LiFePo4. 

I have ordered Walter's PDU here, another very smart man with a great product, hope he does well. His PDU can daisy chain for up to 16 Opus chargers on a single power supply-

Just hook them to a server psu. Cheaper than doing above.

Are the cells in single right now or in bigger packs?

if you are testing single cells up to 8s an icharger x8 is worth looking at.

Agreed daromer, I misread the 20k as 20ah too much looking at the monitor. a 20ah lifepo4 cell would be take a long time in an opus
