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 ...

+ 1

Well, if that's the game...

SOLID... Sanyos and Panasonics are my faves. looking forward to your results!

Don't forget to publish the exact size of these cells.

It'll be interesting to see if the cells are really Sanyo.

Testing has started ..

Interested in hearing your results as well.

So these are 2600's and not 26650's? Are they any good?

2600 refers to capacity (in mAh), not dimensions (26650 = 26*65 mm cylindrical cell).

They indeed are good, possibly even best for single-cell flashlights.

Though not any better than the XTAR 18700's which also use Sanyo cells and cost less?

That’s true, yes. Xtar 18700’s are a better deal, at least at the moment.

Well , so far looking very good ..

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.

Ive calibrated it to match the voltage of my 3s battery packs ..

But the voltage is still out on a single cell ..

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.

Sorry if that's Off Topic...
