The Hexfly lineup of LiPo (Lithium Polymer) batteries are built strong with a strong hard case & heavy gauge electrical wiring. LiPo batteries provide much improved performance than NiCD or NiMH batteries as long as your vehicle is compatible with LiPo batteries. Please inspect your vehicle handbook to make sure your vehicles ESC can accept LiPo batteries and the ESC need to have a LiPo cutoff. LiPo batteries need to be charged with LiPo compatible battery chargers. Lithium Polymer batteries are harmful and may catch fire, cause damage to your vehicle or other if you do not strictly follow the guidelines for managing and charging. Please read your vehicle paperwork before purchasing and abide by all cautioning labels. Hexfly offers LiPo batteries from 3000mAh on up with "C" scores starting at 20C. Take a look at all Hexfly offerings and double check the battery size to make sure it will fit firmly in your vehicle.
