Rate (DR)*: Slingshot Batteries matches all of there
batteries at 35 amps. This processing ensures that the cells
will be able to withstand the current draw of any racing
application as well as weeding out low quality cells.
Rate (CR): Slingshot Batteries charges all there
cells at 6 amps during the matching cycle.
(Sec)*: Runtime is the number of seconds it took to
discharge the cell at 35 amps from fully charged to .9V cutoff
Voltage (AV)*: This is the average voltage of the
cell when discharged at 35 amps from fully charged to .9V
(DET)*: We use the industry standard 5000 sec cutoff
for AV. Obviously the discharge will not last 5000 seconds,
however this setting allows for a full discharge down to the
.9 cut off voltage. Be sure the competitors are using a full
5000 second run out when comparing with Slingshot Batteries.
Internal Resistance (AIR): This is the internal
resistance of the cell. You want this number to be as low as
possible for spec stock and 19T racing. Lower internal
resistance effects how fast the car will accelerate or the
“punch” of the battery pack.
Voltage (CTV): Slingshot Batteries uses 0.9V the cell
cutoff voltage. This is the voltage at which the discharge of
the cells stops and the runtime is calculated. Assuming the
DET is set higher then the runtime of the pack this is also
the level at which average voltage is calculations
* Be aware
there are matchers out there that still use 20, 25 and 30 amp
discharge rates to match their cells. Reducing the discharge
rate will give better average voltage numbers and longer
runtime numbers when compared to Slingshot Batteries. Also
some companies may use lower DET or higher CTV to inflate AV
numbers. Be aware when comparing Slingshot Batteries to
competitors. Just because the numbers are better does not mean
they are better. Slingshot Batteries chooses to use the
highest industry accepted discharge rate and industry standard
discharge cutoff parameters to ensure our customers are
getting the best product possible.
