Virtue N-Charge Rechargeable Battery Pack - Fits all Spires & Rotors

New, Love it, works great, charged it fast and is way better then batteries

Can’t wait to try it out

I’m giving it a three star because this battery wouldn’t sit right in my R2 rotor hopper with the cushioning under the batteries seem too thick and screws too short. I emailed virtue, but never found a reply and it’s already been about a week.
