VEVOR 12V 20A DC to DC Battery Charger, 250W, On-Board Battery Charger for Lead-Acid, Lithium, AGM, Gel, and Flooded Batteries, Smart Multi-Stage Charging, for RVs, Commercial Vehicles, Boats, Yachts

Fonctionne parfaitement et charge nickel juste sue l'installation sur la notice est mal indiquée

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

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.

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.
