Recommended third-party battery manufacturers?

Can anyone recommend any of the companies that are now doing third-party NB-13Ls for the G7X?

Amazon.co.uk offers batteries from Maxsimafoto and Mondpalast - if I'm honest neither name makes me feel terribly confident in the product! Can anyone recommend for or against these companies, or have any recommendations for other third-party manufacturers who provide an NB-13L equivalent?

Many thanks

been using sterlingtek since a G5

I think a search of that name on the forum might yield years of good experiences

edit, I just searched and damn they don't offer it (yet). I queried them to see if it was coming.

Well this sucks

Hello,

We currently do not have any plans on manufacturing the NB-13L battery. Thank you for your interest in our products.

Best regards,

I am trying batteries from DSTE. They arrived in yesterday, I'll let you know how they perform

I don;t have the g&x, but I have been most happy with my Wasabi 3rd party batteries for the 5D3/7D2
Wasabi appears to make a very good battery.
