Will this device support my truck?

Sorry, this battery tester bm310 is only for 12v car battery testing, NOT for trucks.

I have 2 - lithium 51.2v batteries in parallel. What setting do I need to use...48v??..or 60v??

I believe you would want to use the 48v setting.

The ok green light flashes but i am not getting any other indicator and followed instructions. looking to get battery state info. any advice/support?

Only the OK green light is flashing, which means the current battery voltage is in the range of 4.6v to 11.2v, and the car is in the flameout state. If the ok green light and low red light are on at the same time, which means that the current voltage is between 11.2 and 11.6v, and the battery needs to be charged in time The products are equipped with instructions, you can also get this information from the instruction. Thanks for asking, hope this help.

Useless display.

The display shown in the photo in the listing is a far cry from the actual display. The actual display is not visible in sunlight or if viewed from the driver position, unless one rests his head in the passenger seat. Totally useless on a golf cart.

Very Hard to See

Simple and seems to work. Wiring is straight forward. Two big issues. First, the angle of the screen makes it impossible to see if installed in the dash. I saw this in reviews, but didn't expect it to be this bad. Second, I purchased for an EZGO TXT 2002. It is not a good fit at all for the hole that exists for the oem gauge. It is too thick, requiring cutting of the dash and it's so narrow across that the screw holes only match with air. I installed it with some adjustments, but it is really not satisfactory.I put a shim at the bottom to angle the screen up so it can be seen. Overall, it works, but other choices would have been far better.
