iFlight FullSend 450mAh 4S Lipoly Pack


Exactly what your intense combat bots need!  Our 450mAh 4S Lipoly battery Pack is higher voltage than your typical combat robotics 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.

  • This high-discharge Lipo battery has awesome performance with 75C discharge capability.
  • Lithium Polymer batteries are very lightweight cells, but have a greater power density than NiCads and NiMH
  • High quality silicone-insulated wire for high current applications.
  • LiPoly cells do not develop bad memory during charging.
  • High-discharge packs – Get the most from your batteries! A higher C rating allows you to pull a higher current from the same sized pack!

This battery was specifically sourced to provide enough power and the right form factor for our Baby Nautiloid Combat Bot. It will fit effectively inside the top cover.

See the video for installing the battery here. Yes, there’s a trick!
