Dc 12v 24v 36v 48v 72v Battery Meter with Alarm Battery Capacity Indicator Monitor Voltage Meter and Lithium Ion Indicator(Green Light)

Q: Can it be wired into lighter socket

Yes it can. The unit is measuring the state of the battery, so it can be wired into anything that is powered by the battery

Q: Is this 2 or 1 unit as first shows 2.?

The image shown is not my picture. There are two units shown in this image. The unit is flexible, and with care, is able to display various battery parameters. For my application of this device, I merely want to be able to monitor the terminal voltage of a lead-acid car type battery and for this purpose the display is accurate to one decimal point - not that this is necessary for my use. Hope this helps

Q: does it need to be fused?

I don't know but I always put an inline fuse out of habit.

Q: Does the the percentage work ok on a lifepo4 battery? (lithium). Just trying to see if it is a good at indicating low capacity?

I'm not sure that it does accurately: you have to set it up for LiFePO4 batteries, and I don't use the battery below 90% (around 12.6 volts - ish). I understand these batteries can be stored with 50-100% charge (e.g. Ultramax LiFePO4 12V, 10AHr), and I understand that the internal battery management system will protect the battery by disconnecting before the battery is irrevocably damaged. My system warns me of low battery at 12.00 volts (under load) and a "flat" battery at 11.2 volts. If it's dropping below 12 volts under load, I swap to a fresh battery (by a make before break flip switch). If you are intending to discharge the battery to 50% for storage, I'd give it some charge so it's around 12.6 volts, then it should be somewhere between 50% and 100% charge.
