- While I have a Hyperion EOS i720 Super Duo charger which measures IR, I bought this meter for 2 reasons. First, it uses a Kelvin 4-wire design which eliminates error due to any resistance in the test leads. Second reason is the built-in LiPoTool which is based upon a value Wayne Giles uses of 6 Watts/Ah for the maximum safe heat load for a cell. I use the meter to test each cell of every new battery which goes into a spreadsheet. I can now easier see the IR increase as the battery ages and when I should retire it (or move it to smaller lower C plane).
- The meter works great for what its designed for and is simple to use.
- Nice meter. Being able to check 1S battery's is the main reason that I purchased this model. While most good chargers measure IR, I was never sure if I could trust them. I like how when measuring total IR of a pack it will take into account the resistance of the wire and connectors. Helps to find bad or dirty connectors, or poor solder joints on the wiring of the battery packs.
Received my ESR meter in good condition with documentation. Very simple to use.
I was surprise to learn my 3S1P 2200mah Turnigy lipo is well overrated. Calculated safe maximum of 19C when it should be 25C (only 19 recharge on these lipos).
