I bought a Victron BatteryProtect 220A on ebay.co.uk recently (stated as new other).
I received it a few weeks ago here in Ukraine (by using a forwarding company), but only yesterday I've decided to try how it works.
Visually, it looks new but I noticed a few marks of use on the mount holes. So, I'm not sure.
I did a test wiring to the 12v 3w bulb. Positive from the battery to IN. Then OUT from SBP to the bulb +. Negative from battery to GND and directly to the bulb -.I connected it to Bluetooth. It works perfectly by itself. I can configure low/high voltage limits. I see a "P3 under voltage" warning when the voltage drops below the limit. But the bulb is still ON. The load is not disconnected. Yes, I wait for a while, much longer than 90 seconds.
I've tried to disable the load manually via BT. Stills the same problem. The app says "disabled" but the bulb is still ON.
Here is a quick video:
I did another attempt with small water pump
The noise of the pump is a bit different in the "OFF" state.
I've contacted the seller, he asks me to get support from Victron first.
Can anybody help me? Is it already burned, or maybe I did something wrong?
Thanks in advance.
