how long are gmaxx batt straps?
 

my cells are close to 200 mm long will these me long enough, also do they come with side straps also?

or if anyone has a link to some other good velcros i can use

The longest I could stretch the gmaxx XL straps was 12" with only a tiny bit of velcro holding it together. You need to subtract a bit for the two attachment points, but I think they'll hold your 200mm packs in fine if they're not too tall.

They don't come with side straps.

thanks man there here today, and my lipo is only 26mm tall i think it should work fine
