Value for money

Does what’s expected for the price

John Coulter
300 amp battery monitor and shunt

works fine on my 24v 2.5k system. installation instructions are impossable to understand but the drawings are helpful, main thing is the shunt must go fl-2 end to battery 300a to load or readings will be wrong, this is not explained anywhere

brett middleton
300 amp shunt

Easy to install

patrick brady
Shunt Amp/ Volt meter

It got here on time , I have not fitted it yet

Great little meter

Needs better mounting options for the shunt, but works great
