This is my fourth battery from this company, I have always received good batteries. This 100 amp hr battery with Bluetooth seems to be working great, and it was easy to set up the app.

Simple charger and seems like a well-built unit although haven’t used it yet. One issue is with the DC cables after the connector are way too short to connect to either end of a battery Bank. Had to purchase another connector and build my own longer cables

Works as described, constant 40A charge current. Follows charging ‘chart’ as per short manual. Has a short and gradual current increase when powered on. Does not heats up. Fan is not to noisy. Would recommend.
