Default Re: EBC-B20H 20A 12-72V Lithium Battery capacity tester just bought one

ESR just needs to match the manufacturer's specifications, comparing numbers across chemistries and sizes doesn't make much sense - a value acceptable for alkaline cells can be horrible for NiMH and Li-ion but too good for lithium thionyl chloride.

An apparatus such as this is still needed to measure capacity.
