Maybe you feel it's a little expensive,but you will feel it deserve the price after testing sample.
Maybe you want to know how to identify if it's a good controller, I think the simple method is tesing it with full 100% charging current and discharging current.Then you'll find if it's a good controller, the temperature is not high; but the bad controller will be high temp. you'll feel it's hot when you touch it. It's better to test it for long time,if only short time,maybe you can't find if it's good…
As we know,some company will use the lower current controller instead of the higher one.For example, the controller is 20amp,but they use a sticker for 30amp. You feel it's cheaper,but actually, you get it as higher price.
