Hi all,
New to the forums but have been riding my electric bike since 2012!
Recently "upgraded" my pack from the one I purchased in 2012 (52v 10a split into 2 packs in series).
After 6 years my internal resistance of the packs was 8.1 and the pack was going strong (always stored in cool environment with lower voltage etc) but decided to sell it to get a single pack that is easier with 25% more range 12.5 amps
New 12.5a battery not only has an IR of 8.1-8.9 but it gets the same range than my old 10a. Not seeing benefits of the extra weight, size and 2.5amps.
Seller out of PA claims they are brand new but I'm curious if they were left in a 100% charge state, heat, etc (which he denies).
Is there a normal IR range of new 18650's?
Cheers,
Eric
