Bluetooth enabled 4amp 4bay Charger

Pros:
this is an interesting price point for a modern charger unit.
it has CC and CV charging, unlike OPUS. 2amp charge on 1st and 4th bay and 1amp on 2nd and 3rd bay (better than NiteCore)
It shows all 4 batteries charging status in once screen unlike Liitokala Lii - 500.
It doesnt have discharge/tester functionality but you need to ask if you need that feature.
But it has a cool mobile app for iOS and android that allows you to see charging graph, status, change current and turn light on/off - which i think at this price point its cool and a better upgrade to NiteCore d4

Cons:
no discharge test function, durability will be yet to known (its a new product).
