Using this for my 12V LiFePO4 trolling motor battery. Very easy to use and seems like good quality. Would buy again.

This is a very reliable fast charger. Build quality is solid and it charges large batteries much quicker than typical 15–18A chargers. The handle is a nice touch. I’d prefer a digital display over LEDs, but overall very happy with it.

This charger is solid and durable. It's easy to set up and keeps my work truck’s house batteries charged without draining the engine battery. Big help for all the electronics I run.

Been using it for over a year now and it’s held up well. Gets a bit warm, but that’s expected.

What a BEAST of a charger. It’s heavy, robust, and feels really solid. Planning to mount it in my RV battery bay as backup charging. Haven’t fully tested it yet, but first impression is rock solid.

Schöne Ausführung.Die Bedienungsanleitung könnte besser sein . Sonst alles Gut.

Egyszerűen beépíthető. Tudja az igért adatokat. Csendben dolgozik . A legkisebb teljesítményű koncertet választottam , gondolva az autó generátorára is .

Le produit n'est pas compatible avec mon installation T Max (problème sur entrée et sortie pour les batteries) J'attends le retour de l'article qui est dans son emballage d'origine et neuf (non monté)

Hello, The charger is receiving 14 V at the input. The D+ cable is also receiving 14 V when the engine is running. However, there is 0 V at the output. I have checked the fuses and they are all OK. The power indicator is on, but the charger still does not provide any output voltage. I have checked everything I can, but I am not able to do anything more to troubleshoot the problem. I believe the unit is defective. I would like to return it under warranty and receive a replacement or a refund. Thank you. Regards L.W
