Banggood

It arrived quickly, works well.

it's simple & working by the way, watch out the alarm. it's very loud. i remove the speakers.

good looking lipo tester with case

This is not the HJ BX100 Yes, this is much better then the BX100; it's the alarm buzzer I was searching for. It starts beeping at the moment the battery goes under the minimum voltage and it stops beeping at the moment the battery voltage goes back above the minimum voltage. Great, great, great!!! I will buy more of these.

Pita demasiado fuerte para mi gusto. En casa con la mujer cerca no lo uses.

nice product

funktioniert piept aber sehr laut wer etwas löten kann, kann den pieper entfernen

Fantastic little voltage tester for checking your batteries out in the field. Very small and compact with large clear easy to read display. Never send your drone up in the air with used batteries again. No longer will you get them mixed up with full ones with this handy gadget.

It's a kind of bulky bit to be mounted on a quad but certainly very helpful for low voltage alarm on bigger quads.

the items are very good and as per the description
