Not too bad, this has the capacity of 2X of a 18650. Old4570, you can put this into your DB if you want. Thanks.
1st cell 1st cycle Discharged from 4.18V, 1 amp
2nd cell 1st cycle. Discharged from 4.24V (overcharged) 1 amp
Wow, Nice.
Mitro tested it to be 4500mAh @ 5 amps. So that'd be the performance in the TK70. (~ 4.5A)
Nice to see them coming in over 5Ah. Thanks for sharing your results!
I see, they still perform well.
Yep...well worth the usd34 shipped price. Like $17 for a pair of unprotected 18650 2800mAh cells.
Important thing is, they came matched.
I have used several sets of these in the 3D Maglites I have built with XM-L, SST-50 and SST-90 emitters using H6Flex and DW drivers. Performance has been consistent and reliable under varied environmental (temperature) and electrical (amp draw) for the law enforcement officers I using them. I haven't found a better battery yet for "D" cell applications.... Nutz
Have you tried the Ultrafire BRC 3.0V LiFePO4 4000mAh?
I haven't used the LiFe batteries yet... for a couple of reasons. A friend of mine bought a pair of the Ultrafire and both were disappointing... each was only good for about 2400mAh and they didn't cycle well. Maybe he just got a bad pair or maybe a "copy"... so I don't know for sure. Also, in my application I like to have the extra voltage headroom of the LiPo chemistry and the driver H6 driver provides a measure of over-discharge protection as well....
Anyone know more about the Ultrafire BRC's?
I read something good about these a while back. http://m.novaeproducts.com/site/mobile?dm_path=%2Fapps%2Fwebstore%2Fproducts%2Fshow%2F1846436&fw_sig_premium=1&fw_sig_access_token=b800dabfeb8d27577b4d5fa8a051242004bba48&fw_sig_session_key=95f42a3f7ff6cc9cdb0c7f20124ed6dc26d2746e038366cdaf4f8d58e392a3dc-60122423&fw_sig_api_key=522b0eedffc137c934fc7268582d53a1&fw_sig_tier=1&fw_sig_url=http://www.novaeproducts.com/&fw_sig_permission_level=0&fw_sig_time=1316014439803&fw_sig_permissions=none&fw_sig_is_admin=0&fw_sig_social=1&fw_sig=601a5d43ce7b33a1bea36dc6dab35196&fw_sig_site=60122423&fb_sig_network=fw#3312
I just know that they are cheap, 20 bucks shipped for 1 pair at Manafont. hehe....
You can try this for kicks, if your host can take it. The Feilong is supposed to be pretty ok as they specify users to use this for their CSM-360s for best performance.
Don't know how to make a spacer to fit my TK70 180mm cell length tube though. LOL! Any ideas?
Still a little bit affraid using the 3.7V in the TK70?
Th3e Feilong batteries are good quality... but their pricing puts them out of range for my needs. The 32650's are awesome and can handle a 50A draw continuous if you have the need for such (or just want a durable battery) . Pricing is a little cheaper for now if you buy direct from their website... I think $37.00 for a pair.... Nutz
My aliexpress site is 41 bucks shipped probably with registered shipping (need to email the seller). $37 believe is excluding shipping, so would probably run another $10 or so.
No problem at all in the TK70, just posting the results up now.
