Only a 29% positive rating on Amazon but the complaints were mostly about shipping, not the product itself.

No experience with Aegis.

Website is very suspect. No mention of who manufactures the cells. No mention of pack configuration or even how many cells are in the pack!

There is no such thing as a "deep cycle" lithium ion battery. Li batteries are still very fragile, unlike a flooded lead acid deep cycle.

If I have to ask for basic info, no way I'm spending my money with them.
