Works great
Easy install, seems to do the job well. Made for a much easier trip when facing long travel days that otherwise would be draining the camper house battery bank.

A must have for charging lithium deep cycle battery.
Keeps lithium deep cycle battery from overheating vehicle alternator.

Narrow and small terminals now easy to connect
Prods - built strong, works good also Cons - terminals for power cables too small - impossible to use standard cable terminals. Need to grind every terminal from both sides to fit then in narrow spaces. Moreover power connections should be rotated on 90 degrees because it’s difficult to connect to power terminals. Would return products and newer buy VEVOR dc to dc because it’s has terrible power terminals. I love VEVOR products, but this charger must be modified. Attached photos of example good terminals other dc charger.

Works well.
Why did you pick this product vs others?: WORKS great in my dump trailer. Needs to be tweaked as per instructions. Charges battery fast in between dumps.

Funktioniert bestens. Ich habe 400Ah an Batterien drin, die werden jetzt wesentlich schneller geladen. Natürlich sollte die Lichtmaschine genügend Leistung abgeben. Die D+ Leitung ist zwingend notwendig und der gesamte Leitungsquerschnitt sollte nicht unterdimensioniert sein.

Prodotto molto buono un po piccoli gli attacchi dei cavi batteria

It is not bad, It charges in the first stage rate "Bulk Charge" up to a point and then stops. It does not go into second stage charging "Absorption Charge" to complete the charging to 100%. The connection points are not rated for 40 amps or #6 AWG Wire. It would be nice if the D+ connection point was built for a spade wire connector. I wish some of the other manufacturer's built their DC to DC chargers this sturdy.
