Purchased 2 40 amp inverters to charge a 280AH lithium battery in two different service trucks. Neither truck will charge the lithium battery. Hooked up as instructed, it turns on but no output voltage and lithium batteries and batteries goes dead. I have bypass the inverters in both trucks until I can get them to work. No fault light is on just the green on light. I have the dip switches set for 14.6 volts passed on the lithium battery instructions. I have messaged Vevor for assistance and have only received a pdf file of the manual that I already have that came with it. I sure would like to talk with someone but in the messaged it said that they didn't have that as an option for assistance. Now what. Return them? Please help!

I bought this by mistake. I have no use for it not allowed to return it if anyone wants to buy it for half the money let me know. I will never shop here again.

Ik heb de 40 A uitvoering, maar het is een zwakke acculader, hij komt nooit boven de 14 volt, ik heb spijt van mijn aankoop en raad hem af

There is no effing quality control here, the litle screw too hold in the d+ ignition wire sucks and doesnt work for holding in the wire that is required for it to run, so it sucks and is useless and i want my stupid money back. I just spent 2 hours installing it for it to be bullcrap
