I’m very interested in purchasing the hydros wave engine but i am curious about battery backup. I currently run 2 xf230s and 2 xf350s. Id love to hook them to your controller but first I need to know if the newer icecap battery 2.0 24 volt pack will work? What do I need to buy other than the hydros and the icecap battery? I would also like to know if it is possible to use diy 24 volt battery backup to the controller? I ask this because I’d much prefer a diy 18ah 24 volt backup over your 24volt 2.5 ah battery. I can’t justify the money on the controller unless I am able to back it up.
