Digital Multi-cell Lithium Battery Voltage LCD Display for R/C Models
[E3872]

On my 3 cell Lipo it blinks the following on one second intervals:
dSP (initialization message? only displays the first time)
No1
4.09
No2
4.11
No3
4.15
ALL
12.4

Apparently works with 2 to 6 cells. Did not work with a single cell pack (the first cell of my three cell pack), but did work with a two cell pack (the first two cells of my three cell pack).
I would buy it again. It works and (mine at least) looks as described.

I will buy from bestofferbuy.com again. I got what I ordered with no surprises and I got it in 11 days from east coast USA. Cliff
