Firefly Oasis Batteries - Opinions?

[Chris1]

Does anyone here have experience with, and/or opinions about, Firefly 'Oasis' batteries? They sound a little too good to be true. Except for the price, which is about double that of a good AGM. Though if their charge cycle numbers at high discharge rates are to be believed the price is okay. I'm finding almost no information about them, except from the Mfg. FWIW my application is on boats so the sealed aspect is a must.

Stay away from foam batteries.If you want a quality AGM battery use Rolls or Concorde.

Thanks for the response. Can you tell me why the foam batteries are not a good thing?
