Discover EV Traction Batteries?

Does anyone have any knowledge or experience with these batteries? They are being sold as 'premium AGMs' but the price in South Africa seems very reasonable. I might buy 2 4D size.

Heading back to Lake Ontario for this summer. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.

The Discover batteries are built in China, at Vision or Orema I believe, and were designed in Canada. They've been around about 10 years +/- in the market but not so much in Marine.

They were designed to try and equal the longevity of a GEL battery but in an AGM. They have thicker plates than most other AGM batteries and they claim 700 cycles to 80% DOD but I have no idea how they hold up.

The pricing here is slightly higher than Lifleline, Odyssey or Deka East Penn which are known quantities.. Personally I prefer GEL over AGM but in most applications for cruising boats wet cells win the $$/Ah and longevity/$$ equation..

Re: Discover EV Traction Batteries?

The way my boat is set up I cannot use wet cell batteries because of access problems. I don't need to replace my batteries now but these seem like a good deal. The 4Ds are about $500 each and if I leave South Africa within 30 days, which I will, I get the 14% vat back, which is already included in the price. I checked Defender's price for Lifelines and it was over $600 not including tax. There is a problem with the terminal type though.
