For the price it's outstanding.
Good algorithm and charging current.
Did some tests with 65-250 ah batteries with very positive overall results.
If you want to use removeable clamps you must buy it yourself. The charger is normally intended for fixed operation.
Really exceptional value and looks after batteries well in our miniature locomotives.
Only major issue is not polarity protected so best for fixed installations otherwise get it wrong and that is the end of your charger.
