Moduls fit the originl package 100%. Easy to mount with medium skills. No extra tools or wires needed. Good charge balancing. Shipment very good. I asked them to care shipement by sea free of duties. Top service. Mavis helped me from the first requst with kindness and top information. I've just mount the battery. Now I need to test, but till now I recommend Ennocars products ad services.

The instruction the number on batteries. They’re not visible enough enough and how you put them in order for a specific car and how to route the cables, positive and negative on the battery. for example Toyota Camry hybrid 2009 I have a hard time routing the negative cable. because the design of the battery is different from one to another.
