Default Re: Panasonic 3400mah 18650 Cell Now Available!

I got a grey shrink wrapped Sanyo 18650 today in a laser I bought off LPF. I never saw that color Sanyo before. No info on the Mah, does anyone know what that battery rating is? Are these gray wrapped Santos's common?

I've been using Sanyo cells for about 10 years and have not seen any with grey shrink-wrap.

So they're either re-wrapped, or fakes.

Pry up the shrink-wrap and look for Red underneath.

Just received shipment of the new 10 amp discharge rated Sanyo 3500mah cells today.
Measured the Internal Resistance @ 26 milliohms .
A very good spec, since the previous 3400mah cell was ~50 milliohms.
Noticed that they have raised the positive terminal enough that they will work end-to-end in series.
See photos in 3500mah link below. No need to order the Positive pole buttons any longer.
