Li-Po Battery Voltage 3-Digit Indicator

Pros: Compact.
Accurate enough.
Shows the voltage status of each cell.
Can be used also for one cell voltage monitoring (like 12 PB battery but maybe for short time - I do not know if it can work constantly at high voltage).
Assembled in transparent thermoplastic (but not dust and moisture proof).
Well visible signs for positive and negative terminal for correct connection to the battery.

Cons: A bit expensive compared to other similar products but the design is more compact than them.
Arrived without any user manual and without specification for accuracy and operating voltage ranges.
Not dust and moisture proof.
Consumes energy only from the first one (two) battery cells (next to the negative terminal). If used for constant battery status monitoring - the first cell(s) will be drained faster than the others.

Other: Useful and easy to use (if you know how to connect it).
It will definitely help me for fast check of the status of my batteries.
