I am considering new batteries for my 36V Estar electric go kart from Kango EV. Gruber and Tempest have a 12V 35Ah battery. The Gruber is $57. and the Tempest is $79. The Tempest claims to be a "true deep cycle." I purchased a different 12Ah battery from Gruber a couple of months ago, and it has been working fine in my kids' mini electric quad. Below are links to the info on each of the 35Ah SLAs.
Does anyone have any suggestions as to which would be better or experience with Tempest.
Thanks for any help on this.
