Constant Current Sink Recommendation

(1/1)

lukegalea16:
Hi,

I'm looking for a constant current sink (ideally something off the shelf) to test my 3.6V battery under 2A-4A (2A is more realistic) loads for approx. 4 hours.
Initially I was going for a power resistor but the current would change with decrease in voltage.

Can anyone recommend some lab test equipment please?

I have a ET5410, I had mine for $175.
And for this kind of jobs it is ideal because it has a discharge option, so it won't over discharge your battery.

Aliexpress

I had the below one for some time

But it was always in the way because of no good housing. So gave mine away an bought the ETS5410
