Yea, but just a bit. It’s only noticeable at high currents

He’s doing a GB soon :slight_smile:

This difference might be due to the equipment (The difference is about 0.002 ohm).

I have switched to new equipment for these test and all future NiMH test. I have batteries for 8 more NiMH test, some of are already tested and will be published soon.

Cool, thanks

For those looking for a local source, these appear to be the same as the Duracell 2450mah NiMH rechargeable, Made in Japan, batteries available here in Canada (and I assume elsewhere).

The Duracell 2450mah NiMH MIJ batteries have identical end caps to the Eneloop pro 2450mah batteries, and are sold alongside the old white top 2000mah ‘Duraloops’.

I have a pack awaiting a Sunwayman F40A. :slight_smile:
