Sanyo - Protected 18650 High Capacity Rechargeable Battery
Mars Fire Sanyo battery :
Got a pair today for testing , been very impressed by Sanyo cells , and if I was in the market , Sanyo would be a top choice , so Im really looking forward to testing these cells .
Should be Sanyo 2600 + protection circuit .
Charging the batteries right now , and hopefully have the review up by the week end ...
+ an opportunity to give the Turnigy a bit of a run ...
Turnigy Accucell 8150 is not nearly as (accucell / as in accurate) as one would have hoped .
I calibrated it for 3s cells , but on single cell (3.7) its out a good 2.5 to 3 tenths of a volt less than actual battery voltage resulting in early termination 3v
But not to worry , the 1A discharge was still some what good ..
Just started the 2A discharge ... Ive switched over to Nimh setting to adjust for the inaccurate voltage reading
Try 0.1A discharge - is it still showing smaller voltage than actual battery voltage?
If not, there's something with high resistance in your path to the battery. If you used something like 1x18650 holder from DX with wires as thin as hair, that could be the reason.
Old4570: Another strange thing. Manafont is releasing this Sanyo 18650 in semi-clear wrapping with no capacity (over)claims. I agree with you this is a promising trend, however then they list this MarsFire 26650 in Trustfire-esque wrapping with inflated capacity of 5000mAh. I want to trust Manafont (No really, I do), but inconsistencies like this make it hard.
