This is a great deal! I was looking at the Victron Blue Smart chargers this morning but for ⅓ the price and all the same features besides Bluetooth, I'll take this!

I had not a great experience with this.

My first one arrived with a cracked screen

My replacement wouldn't charge my battery at all

My 3rd has worked fine for the last few months.

I wonder how these compare to other brands when charging the standard or AGM's?

i just got this and own the victron 20amp too. the charger itself seems incredibly cheap, barely any weight to it, but it works. i don't know how it doesn't need any large heatsink like the victron or even there non smart 20 amp(the all black one i owned tool

I have this exact charger and I clamped it while charging my 150ah EcoWorthy branded LiFePo4 battery near the beginning and again near the end of the charge cycle. I can vouch that it does a constant 22 amps which is 10% more than rated. Not bad! It got pretty warm but never so hot that I couldn't keep my hand on it. 10 out of 10 in my book especially considering I paid 75 dollars for it about a year ago. At this price, I'll probably buy by a second one. Redundancy is vital when building an emergency power setup.
