ADVANCED BATTERY MAINTENANCE Would you do without a fuel gauge in your vehicle?
If you depend on batteries to provide power in your boat, voltage and that’s not really enough to help you manage caravan, motorhome or even house, it’s essential that you your electrical consumption efficiently.

If you don’t know how your battery’s condition - simply fit one of the battery many Amp hours you have left or what the battery’s voltage management panels shown here. We have different is, you can very easily find yourself with dim lights, erratic models for different applications but they all do essentially water pump and no TV or worse! Simple meters that are the same job: they help to keep you informed about the installed in many caravans and motorhomes only show the condition of your batteries.

SmartGauge is a SmartGauge uses an incredibly complicated set of British designed and manufactured battery monitor which is easier to
computer models and calculations to measure the battery’s state of charge and to then calculate the % of capacity remaining. It will work with all types of lead-acid battery and gives a 100% accurate indication of the battery’s condition.

level of accuracy and no volt meter can either unless the battery has been at rest - with absolutely no charge or discharge - for 24 hours. Even then, a voltmeter will, at best, indicate whether your batteries are being charged or discharged and not a lot else.
what’s happening to your batteries, you need SmartGauge. Conventional battery monitors use a shunt to measure the
Amps being put in or taken out of a battery. However, the results shown will be unreliable unless the monitor “knows”
the battery’s state of charge at all times. SmartGauge shows you how much power you have left as a percentage of your currently available battery capacity.
Other meters only show you how much power you may have
different and will be completely different once the batteries have been cycled a few times. A standard monitor will inevitably get out of sync with the battery that it’s measuring.
Discharging a battery by 10A for an hour and then recharging it by 10A for an hour doesn't get the battery back to the same point!
A SmartGauge will show you with complete accuracy exactly how much power you have in your battery as a percentage. It will not show you the current (Amps) being put in or taken out. For this job, an Amp hour counter is necessary and one can be used with a SmartGauge.
With just two thin wires required to connect SmartGauge to a
battery (three if you want to monitor two sets of batteries), installation could hardly be simpler. The display panel fits flush to the wall (hole required measures 101mm W x 65mm

NASA MARINE BATTERY MONITOR
COMPACT C8453 £114.99
The “Compact” model uses two screens to give you all the information you need but in a display measuring just 124 x 62mm x 23mm! It’s available in black or white finish. Simple to install and easy to use, the “Compact” is ideal when space is restricted and where battery capacity is from 0 - 600 Ah.
Screens show the batteries’ voltage, how much current is going into or being taken out of the battery and how much time is left before the batteries are fully charged or discharged.
