Would people be interested in KEEPPOWER batteries?

It might help with future searches if you correct the spelling to “Keeppower ”. :slight_smile:

I. the 18650's. possibly 2 pair or 4 each. But it wouldn't be until the 3rd of each month. You could pm if youd like

They dont. I have dismanteled a few.

Unfortunately for you I can already buy them for similar or cheaper with free post, mostly from Walbuys, Fastech or Orbtronic.

Hi,

Care to provide a link to FastTech’s KeepPower batteries offer ?

Thanks,

Good eye Woody.


If anyone is really interested shoot me a PM of what you would like to get.


Orbtronic is per battery. Not by the pair.

I also don't see where Fasttech or Wallbuys has NCR18650PD protected cells. In my opinion them and the UR18650FM are the two best protected cells right now. Based on their discharge curves

The protection on the PD trips at 7A, so having protected cells aren’t that useful if you want super high discharges. For high current situations you want the UR18650FM because it’ll last the longest, then the NCR18650B, then A and then PD last. PD is best suited for discharges higher than the UR18650FM and NCR18650B can handle without noticeable sag, eg. 6A+ (which is not common).

If you’re only using at 3A the NCR18650Bs win runtime wise, and at 3.5A+ the UR18650FM win.

They sell Panasonic NCR18650B 3400mAh which is what KeeepPower uses.

If you look here even though it says 7A trip during the testing it tripped at 9A. http://lygte-info.dk/review/batteries2012/EnerPower+%2018650%202900mAh%203C%20%28Blue%29%20UK.html

Look at the comparison here: http://lygte-info.dk/review/batteries2012/Common18650comparator.php

The 3400 beats the 2900mah up until 3A. At 1A and 2A I agree the 3400 is better.

Granted all 3 are amazing cells though!

Thanks for this interesting tidbit.

Has anyone on BLF ever performed an illustrated dissection documenting the evidence for KeepPower cells lineage ?

I plan on making an order in the next few days. PM me if you are still interested. I can order anything that Keeppower carries.

The prices should end up a little lower than the OP prices.

Are the 26650 Protected?

Yes they are.

Any idea for what price Keeppower 18350s and 18500s (protected or unprotected) would go?



2x 18350 900mah= $14 shipped

2x 18500 1700mah= $16 shipped

I guess HKJ’s results speak from themselves.

can’t see ’em; can you speak for them? or check that link?

Batteries and chargers

Kind of stocked up for now, but would be nice to have a US source for these again.

Btw, quick note, the 18350 batteries are A LOT longer than their unprotected counterparts. I have two, and have never actually been able to use them, just charged them, and then discovered they are too big to fit.

If you do stock them, getting 16340's and 14500 would be a safe bet.

Sorry, now edited - thanks NightCrawl
