• Exactly what your bots need!  Lithium Polymer (lipoly) batteries are very lightweight cells, but have a greater power density than NiCads and NiMH.
• Lipoly chemistry can supply its rated current for longer than NiMH or NiCad equivalents, which means your weapon and drive will go full-power for longer, rather than sagging voltage as it discharges.
• These cells have no problem with the large current requirements of combat robots.
• LiPoly cells do not develop bad memory during charging.

Specifications:
- Configuration: 2S (7.4V) 450mAh or 3S (11.8V) 250 to 300mAh
- High quality silicone-insulated wire for high current applications.
- Mating connector: JST
- Balance connector on every size for ensuring packs are at their best before an event!
- Max charge rate: 2C (2x the pack mAh rating) - the B6 Pro Charger and 12V Power Supply are a great charging solution.
* Do not discharge Lipo batteries below 3.3V per cell (6.6V for a 2S pack).
