I have two of these that I ordered in error. They need a Spektrum smart charger.
https://www.amazon.ca/Spektrum-11-1V-3200mAh-Smart-LiPo/dp/B08TKMBV5L/ref=sr_1_5?crid=EO42JDIE9HVR&keywords=spektrum+smart+g2&qid=1694042184&sprefix=spektrum+smart+g2%2Caps%2C380&sr=8-5
I paid $65 each. Asking $60 each. New in box, never used or charged/discharged.
If you would like to buy them I can arrange drop off at the field.
Thanks
Gord
