Summer Shutdown

Every year we close the offices to give all of our staff a well earned rest.

This year we shutdown on Wednesday 8th August and open again on Tuesday 21st August.

The website will remain open, but any orders placed will not be shipped until we reopen on the 21st.

Battery Monitors

Battery Monitors

Digital Display's for monitoring Battery state and charge/discharge rates. Allows you to know monitor precisely the state of charge and remaining capacity in your battery bank.


Prevents discharging your banks too deeply, thereby preventing permanent damage to your cells.


Displays will either have a bar-graph style "fuel gauge" or will display a percentage remaining figure. Configurable alarms are also included.
