How do YOU measure the IR of a Lipo?

[dkalwishky]

I'd like some recommendations on something that will measure the internal resistance of a Lipo battery.

I know some chargers do that but I'm not looking to buy a new charger.

DK......here's what I use. Affordable and pretty reliable and accurate.
Got mine back in the middle of December and have been measuring all my new (4-4S & 6-6S) Admiral IR's and noting that with date on the backs of the packs.
They been on sale for several months......a $30 meter for $10 plus shipping that cost $2.62, how can ya go wrong ??

How do you connect to it? I don't see anyplace for a charge lead. Do you only use the balance plug? Not much info on this. Doc

Doc; it will read from the balance cable.

Thanks Warbird Charlie, I just ordered one from eBay for $13.99 (shipping included). I know that $2 more than you paid but I'm OK with that. Turns out Tenergy has an eBay store.

For anyone else looking here is the eBay link.
