This cell will become more available soon so I wanted to clear up some incorrect ratings info that has been posted.
The 9.6A "Max. discharge current" specification in the datasheet states that it is "not for cycle life". This means it cannot be used when comparing the current rating of this battery against others that have a current rating that ensures a long cycle life (number of charges/discharges).
In the datasheet's cycle life performance table they use a 4.8A discharge rate to meet the specification for good cycle life, 500 cycles for the 48G. But other batteries only use 250 cycles for the life of the battery. This means the continuous current rating we would use is somewhere in between, probably around 7A-8A.
I've been sent screen captures of vendors/distributors saying this battery has a 35A pulse rating. This is not true! Like the ridiculously high "pulse rating" you see for the 25R and VTC batteries it comes from a misreading of the datasheet.
The 48G has a "Max. pulse discharge current" specification of 35A for 10 seconds. This is not a rating! This is a one-time pulse capability. It cannot be a repetitive pulse rating unless you know how long you have to wait between pulses and what criteria they use to set the rating.
The "max pulse" numbers are only meant to be used for designing the battery pack protection electronics. These numbers cannot be used for comparing one battery to another.
Here's one reason why...
The internal resistance specification for the 48G is <=50mOhms (0.050 ohms). Let's assume 40mOhms.
If we pulse the 48G at 35A that results in a voltage sag of 1.4V. So this battery will instantly drop to 4.2V - 1.4V = 2.8V on the first pulse. It will then drop further in voltage as the battery is discharged.
That's why 35A cannot be used as the "pulse rating". It is undefined and results in huge voltage sag that makes the battery useless.
So be careful when you see numbers for a battery that seem fantastic. The details matter a LOT. I hope to be testing this battery within a few weeks.
