Galaxy 300mAh 2S Lipoly Pack


Exactly what your bots need!  Our Galaxy Battery 300mAh 2S Lipoly (Lithium Polymer) is a very light weight cell.  All lipoly batteries hold a higher percentage of their capacity at the rated discharge rate than many competitive products on the market which means longer run times.
• These high-discharge Lipoly batteries have no problems with the large current requirements of combat robots.
• High quality silicone-insulated wire for high current applications.

Battery 300mAh 2S Lipoly

Note:  Each cell has a nominal or resting voltage of 3.7v.  Therefore, a 2s battery has two cells in series or 2S.  This equals a nominal voltage of (3.7v x 2) = 7.4v.  A 3S battery would have three cells in series and a nominal voltage of (3.7v x 3) or 11.1v.

  • Configuration: 2S (7.4V)
  • 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 (9.9V for a 3S pack).

Add 5mm to the length where the wires exit. Below are usable dimensions, not the slimmest or average size!
