Recommended assembly method for combining cells into strings:
Series Strings:
Cells can be combined together in “series strings” to achieve higher operating voltages by connecting the positive terminal of one cell to the negative
terminal of the next cell. Strings of series cells should be connected together via the solder tabs welded to the cell. Removing the solder tab and soldering
directly to the cell will damage it.
Cells can be combined together in “parallel strings” to achieve higher operating capacities by connecting both the positive and negative terminals of
adjacent cells to each other. Strings of parallel cells should be connected together via the solder tabs welded to the cell. Removing the solder tab and
soldering directly to the cell will damage it.
Parallel Strings:
Attaching Balance Cable: (optional)
Balancing Cables sold seperatley as accesories
2S Configuration:
3S Configuration:
Balance cables can be attached to your custom configuration when creating 2S (2 batteries in series) and 3S (3 batteries in series) configurations.
Please see the illustration below for attaching balance cables to a 2S or 3S pack.

Safe handling and disposal guidelines
• For optimum life and performance, charge only on Hypersonic
TM
Sonic Charge
TM
battery charging system.
• Do not disassemble the battery pack or attempt to solder connections directly to the component cells.
• Keep out of reach of children.
• Do not incinerate, dispose of in fire, or heat above 71°C. Dispose of used batteries in the proper manner.
• Dispose or recycle batteries by wrapping in a plastic bag and placing in regular trash, or check with the
Re-chargeable Battery Recycling Corporation at www.rbrc.org for a battery recycling drop-off location near you.
• Hypersonic
TM
lithium-ion batteries can be charged up to 4.2V per cell without hazard. Once 4.2V per cell is exceeded gas pressure may build up
inside the cell and cause a one-time safety vent to open. Should this occur, the battery will be unusable and must be replaced. The damaged
battery should then be disposed of in the proper manner.
• Hypersonic
TM
lithium-ion batteries are inherently safe and do not pose a fire hazard under improper charging conditions, but are capable of very
high discharge currents. Take precautions to avoid short circuits; considerable heating will occur through the shorting conductor.
