Good charger at a fair price. Price is right, will do 6 amps, and the clips have metal hinges and not plastic. Two things to be aware of: 1. after 24 hours of charging it turns off, you have to restart. 2. if your battery is really low, and under 10 volts, this charger won't work on it and will give you an error.

Works. Switched amperage that doesn’t reset is a key feature for rv banks. Problem is 24 hour “protection circuit” that turns off the charge if not finished. Big bank? have to restart after 24 hours. Multiple banks receiving part of the charge? Have to restart. Drawing led light power and fridge? Only powers 24 hours and then gives error light. If there some way of turning off the 24 hour “protection” i would rate higher. Fan is wimpy and I won’t run at 6 amps until I get computer fan to actually cool. Have it standing on end to add convection cooling. Seems designed for smaller batteries. Add another switch for 24 hour shutdown on only 2 or 4 amps and build with 24 hour cycle cooling. I would pay double and buy 2
