G&P M4 Defender battery ideas

[Lez9]

Hi guys I am after some advice please, I have a G&P M4 Defender that currently has a 8.4 2200mah crane stock battery with a deans connector. I'm happy enough with the battery but always good to have a spare or better one, could anybody recommend any that would help. Not necessarily won't lipo.

 

Thanks Lez.

either a 7.4v LiPo or a 9.6v NiMh, either will perform better than the 8.4v NiMh you've got at the moment.

Thanks with the lipo would you change anything internally. Lez
