There are many of these that look the same, chances are if it's cheap it is exactly that, we use these meters ourselves and have tested extensively, unfortunately, there are many copies made by many "factories" and you don't always get what you pay for.
Just because they look the same does not mean they are, many are sold and freight forwarded, we stock these and you are welcome to arrange inspection and pickup.

Lifepo Batteries users please note the SOC will be wonky due to working on volts, when it does drop it will drop quickly, due to the way a lifepo BMS displays voltage, for a more accurate meter you will require one that measures amps in and amps out.

Ideal for 12 volt Lithium, Lifepo and AGM batteries, Any battery below can be set, but 12volt Lead Acid or AGM is pre-programmed.
This is the deluxe meter with the temperature sensor cable

This meter does not come with battery clips as all installations are different, it has a red for positive and black for negative, the cables are not thick and heavy as the meter only requires a miniscule amount of power to operate.

We now have surface mounts available for this meter. They are 3d Printed so some lines marks to be expected. the mount supports 3 variants of meters, you will get this meter with the mount.

Caution! before throwing out the packaging, please remove cables from the bag!
