Well I know I have told some about these Hi-Max batteries on here and some don't even know about them or where to buy them. But they are rated excellent batteries by those that have tested them here like old4570 and others who have bought them. But I wanted to tell those that may be interested in trying them where they can buy them. You can buy them however you like in smaller or larger quanities. I really like mine and I think they rate up there with the Xtars for value.
Are they a Sanyo cell dude?
I like my XTAR 2600's.
Yes, they are. And confirmed over 2500mAh @3A discharge.
2300mah at 3A and they are not Sanyo.
Seller told me that there's Sanyo cell inside. And from local forum:
It doesn't quite match with benckie's results. https://budgetlightforum.com/t/-/5082
But then your photos actually show a discharge down to 2.75V. Which makes more sense.
But even so, the results for the Hi-Max seem even better than the unprotected Sanyo 2600 which is generally 2470mah.
The Hi-Max did 2615MAh with a protection circuit which definitely adds about 30mOhm resistance, depending on the voltage of course. Less at higher voltages. But even so the Internal resistance is about 70-80mOhm for the unprotected Sanyo 2600 and the Hi-Max have a 156mOhm resistance.
So they can't be Sanyo 2600.
Benckie measured 94mOhm resitance on the Redilast 2600, which makes sense for the Sanyo 2600, again if we think about the 30mOhm resistance or less added by the protection. In the case of Redilast they use good circuits and it is probably 20mOhm.
The results you have post are very good, still the higher capacity and higher internal resistance of the cells makes them look like other cells than Sanyo 2600.
Thanks guys,
As I already stated here https://budgetlightforum.com/t/-/1538#comment-102587 wrapper is good but after extensive use it starts to show potential weak spots.
How do you re- wrap a worn out battery? I plan to add protection to some of my batteries but couldn’t solve wrapping in my head.
Here you go my friend;)
Going to 25mm will give a slightly thicker wrap as well.
UK seller here is reasonable?
Oh, that regular shrink wraps work then. I found white series in DX. I’ll get one of those. I hope I can find one for a 26650.
Have you tried regular shrink wrap? I'm asking since it tends to be a bit "rubbery" and regular battery shrink wrap usually is harder. I'm afraid it might cause to much friction so the battery get stuck in the flashlight.
