Health and Lifecycle
SuperLight Batteries display a Health percentage value, called State of Health (SoH).
State of Health is expressed as a percentage of the ratio of predicted Full Charge Capacity (calculated at 25°C) over the Design Capacity (nominal capacity of a new pack).
Best practices
To get the most out of your SuperLight packs there are a few things that you can do to improve performance and longevity. 
Temperature
Li-ion batteries operate best around room temperature. This means you will get more flight time out of the pack, and less capacity loss over the life of the pack. When able to, we recommend charging your packs after they have cooled from flight, at room temperature for the best longevity.
Storage
To store your batteries for long periods of time (months or years) we recommend charging them up to around 50% SoC. 
Lifecycle
SuperLight batteries typically have a lifetime significantly longer than 500 cycles. We have tested them to over 1000 cycles with greater than 80% capacity remaining. 
Over time the batteries will lose some capacity, however, they can continue to be used as long as desired with lower capacity. 
Superlight batteries should be disposed of in accordance with local regulations on battery and electronic waste. 
Hard Reset
In the event that the firmware locks up or an unforeseen issue occurs, there is a method that allows resetting the battery controller. Note, you should not use this in normal operation - it should never be required. That said, if it is unresponsive, you can try this method to reset the battery. Push and hold until the display goes blank, then release the button (approx 15 seconds). The battery will restart.
Firmware Update
the SuperLight Firmware Utility is not currently available to the public, as we have not updated the batteries beyond their release firmware (1.9/1.10). 
​
Download the SuperLight Firmware Utility from the product downloads page.
Make sure the battery is powered off. If not, press and hold the button for 5 seconds then release to turn off. 
Connect the battery to a PC with a USB cable.
Press and hold the battery button until the display shows "Firmware Update" mode.
Open SuperLight Firmware Utility on PC and follow directions.
If USB C to C cable doesn't work, try USB A to C cable.
Checking The Battery Firmware
Tap the button on the SL battery while it is powered off to check the current firmware version. 
Troubleshooting Tree
A troubleshooting tree is a roadmap of all the avenues available to test when searching for a solution.
Fault Codes
The Health screen will show fault codes. If there are multiple fault codes the fault screen will scroll through displaying them. 
Some faults are latching, and require that a user ejects them from the system re mounts them to try again if the issue has been resolved.

Cause and Action
1 (b0)
Cell Over Voltage HW
Remount
One or more cells is over voltage and this was sensed by hardware. Try allowing to balance by leaving on a charger, then retry. It could also be due to extreme water ingress. Allow battery to dry and retry. Retry a few times, then discontinue use if it persists. 
2 (b1)
Cell Under Voltage HW
Remount
One or more cells is under voltage and this was sensed by hardware. Try allowing to charge and balance by leaving on a charger, then retry. It could also be due to extreme water ingress. Allow battery to dry and retry. Retry a few times, then discontinue use if it persists. 
4 (b2)
Short Circuit Dsg HW
Remount
The pack outputs were likely shorted, or extreme high current discharge occurred for too long. Ensure there is no possibility of a short circuit, then retry. Retry a few times, then discontinue use if it persists. 
8 (b3)
Over Current Dsg HW
Remount
A high amount of current was discharged for too long. The application may not be suitable for this battery. If possible, do not load the battery as heavily. 
16 (b4)
Over Current Chg
Remount
A high amount of charge current was sensed. Make sure a compatible charger is being used. It's also possible to trip this is heavy regen applications such as EVs. Ensure application stays within fault range. 
32 (b5)
Over Current Dsg
Remount
A high amount of current was discharged for too long. The application may not be suitable for this battery. If possible, do not load the battery as heavily. 
64 (b6)
Over Temp Chg
Cool Down
Allow battery to cool down, then retry. Optionally, leave charger connected. Charging will resume when temp is below charging limit.
128 (b7)
Over Temp Dsg
Cool Down
Allow battery to cool down, then retry.
256 (b8)
Over Temp PCB Chg
Cool Down
Allow battery to cool down, then retry. Optionally, leave charger connected. Charging will resume when temp is below charging limit.
512 (b9)
Over Temp PCB Dsg
Cool Down
Allow battery to cool down, then retry.
1024 (b10)
Under Temp Chg
Heat Up
Move battery to warmer environment, then retry. Optionally, leave charger connected. Charging will resume when temp is above charging limit.
2048 (b11)
Under Temp Dsg
Heat Up
Allow battery to cool down, then retry.
4096 (b12)
Under Temp PCB Chg
Heat Up
Move battery to warmer environment, then retry. Optionally, leave charger connected. Charging will resume when temp is above charging limit
8192 (b13)
Under Temp PCB Dsg
Heat Up
Allow battery to cool down, then retry.

Battery is empty. Charge!
32768 (b15)
Cells Out of Balance
Allow balance
Leave charger connected. This allows the BMS to bring the affected cells back into balance.
65536 (b16)
Pack Measure Error
Auto if corrected
There has likely been a hardware error. Retry a few times, then discontinue use if it persists. 
131072 (b17)
Cell Extreme Low V
None
There has likely been a hardware error. Retry a few times, then discontinue use if it persists. 
262144 (b18)
AFE I2C Comms
Auto if corrected
There has likely been a hardware error. Retry a few times, then discontinue use if it persists.

Fuel Gauge I2C Comms
Auto if corrected
There has likely been a hardware error. Retry a few times, then discontinue use if it persists. 
1048576 (b20)
FET Short Error
None
There has likely been a hardware error. Retry a few times, then discontinue use if it persists. 
2097152 (b21)
FET Over Temp
Cool Down
Extreme discharge has likely occurred. Reduce load and retry. Retry a few times, then discontinue use if it persists.
