10C current draw capable 18650?

Hang on, are you saying you can suck this thing dry from fully-charged in 6 minutes and it won't overheat or vent or anything?
 
That battery is NOTa LiOn and requires a different terminal charging voltage. Don't charge it on a DSD charger or normal LiOn charger.

From the "Cautions" section of the product page.
Li-Fe-PO4 battery must be cut-off at 3.8V/cell condition when charging.

The nominal voltage is listed as 3.2 V vs 3.7 V for a LiOn and is a function of the battery chemistry. You can probably find a bunch of information on them by searching for Saphion in the r/c forums at rcgroups.com.

I am begining to find that these (Lithium Iron Phosphate) batteries are very new and I am still trying to learn more. batteryuniversity does mention a Lithium phosphate battery and they also state "There is only one way to charge lithium-based batteries." this refers to the 4.2 chargeing current. However I don't think it applies to these new batteries.

Evidently the manufacturer that I think developed them considers them a "Lithium Ion technology" but they definitely have some different characteristics.

I have (4) from this mfg, R123 purchased from AW

click here

I have charged with Triton and a Li-on charger from Battery Station for R123's (2 bay). After charging, they drop to 3.6V very quickly. Battery life may be somewhat lessened.

I believe that they are considered Li-on chemistry, however, they are "safe"........the link to Saphion, explains more and is indicative that they have been on the market for some time.

Ultrafire makes a charger, availible from Lighthound and AW that will charge to 3.7V; I haven't used but would guess that it will charge to over 4V and then drop. AW or Lighthound may be able to confirm this as both provide excellent customer service?

Lithium Iron Phosphate cells are very save saver than even nimhs they are quite hard to dagage and take abuse well, I woudl recommend a CC/CV charging method with a goo dbench supply and a pair of MM's to monitor voltage AND current.
 
The sony cells I linked to may be charged till 4.1V according to Sony, so no big deal when you charge them with a charger that says it goes to 4.2V.

The Sony cells you linked to appear to be conventional LiOn. The ones he asked about aren't and shouldn't be charged to 4.20 V.

So, Is it at all posible to charge these with a DSD. From what it sound like, I wouldn't have to worry about them blowing up. Would it just sorten the lifetime of the cell.

Yup it's possible and you PROBABLY wouldn't start a fire, etc. It would probably have a drastic effect on cell capacity and life cycles though.
