Nice upgrade over LED
I swapped out the light bar that indicates charge level only thru 4 green bars and one red bar. With an electric cart you need accuracy meaning numbers and not light bars. Why do I say this is? Because my cart stopped two blocks from home on a big street here in Philadelphia. The previous indicator shows flashing red most of the time while driving and goes back to green when stopped. The light bar even goes to a blinking red while being fully charged under full acceleration. (Big Battery Eagle's @ 90 mAh lithium. Great battery system. Only batteries I've seen with digital readout displayed on each battery.) So as I was driving down Haverford Ave from a local community center it just konked out. Again, get rid of the old led battery indicator and get a digital one with NUMBERS. I gave 4 stars because temp not accurate. Today was in 50's and this showed upper 60's

Seems to be very accurate
It seems very accurate but a little too small to see from a distance

Love it.
I really like this little monitor, so far this is by far the best battery monitor or voltage display that I have bought. I have bought several others but they all only have voltage only, this has a digital read out like 12.5 then has a battery bar like a cell phone so it has that display, and then they added the present % of battery so that makkke three different battery displays and it has a temp.

It works
Works okay but the wires are so thin can't get connectors on them

GARBAGE, GROSSLY INACCURATE! Capacity WRONG due to LINEAR CALC! Settings lost on power loss!
Carefully followed programming instructions for LiFePO4 12V, battery type "F4", with 0% at 10.0V and 100% at 13.6. Capacity is COMPLETELY WRONG at every voltage in between because this meter makes a straight LINEAR calculation instead of following standard MFR curve. As photos show, halfway between 10V and 13.6V is 11.8V as a simple LINEAR calculation, and this meter INCORRECTLY declares 11.8V to be 50% capacity, but the standard 50% capacity voltage for a LiFePO4 12V battery is slightly above 13.1V! At 11.8V the actual capacity is BELOW 8%, A HUGE ERROR!!! To make matters worse, SETTINGS ARE LOST WHEN CHANGING BATTERIES! To add more frustration, reprogramming means having to reach the "SET" button on the REAR, so if you mount the meter in a panel YOU'LL HATE IT! I'm returning this one.

Reads correctly.
