Question about Amewi racing catamaran

Should be this one according to the manufacturer's page: Amewi Lilon Akku: 7,4V 1800MAH (7.40V, 1800mAh)

Sorry, that is wrong. That applies to the Amewi Super Mono X. I have not yet found a replacement for this racing catamaran either.

You can use all 2S or 3S LiPo batteries with an XT60 connector. I also bought the XT60-T connector, which fits almost all 2S/3S batteries available from Galaxus...
