Eachine Racer 250 Lipo Battery

Recommended Posts


Hey everyone, quick question; What battery can I use for my Eachine 250 Racer? It came with a 1300mAh 4S battery and I would like longer flight times. I understand that I should probably buy more batteries and another charger but I want to make sure I am buying quality parts.
Any suggestions? Or should I just stick with having more stock batteries?

Hi @DivenParker, you should be able to use 1800-2000mAh for longer run time. I don't have exact calculations...that range will produce a heavier battery, so at some point you lose the advantage. And if you're working with limited space, most 3S batteries up to 1500 mAh are about 70mm long...after that they increase to 100mm.
