Gemini_mall® 12V Lead-acid Battery Capacity Tester Panel Power Voltage LED Display Indicator

Very good value for monitoring battery level. The unit is clearly designed for panel mounting but can easily be made into a stand alone unit. Am using it to check the level of charge on a 12V solar power system and it is ideal to give an easy overview of battery condition. Was considering building my own monitor but this was so cheap that it wasn't worth the effort.

Gemini_mall® 12V Lead-acid Battery Capacity..I actually bought 2 of these, both for my boat, the first is to show the condition of the engine battery and the second for the lesure battery. Both are working perfectly and are giving me a much better idea of drain on each battery.
