People like you use Tracer Power for: Portable Lighting Solutions, Point of Sale displays, Mobile Advertising, Covert Surveillance, Remote Monitoring Equipment, Outside Broadcast Solutions, iPhone charging, Portable TV/DVD players, and many other 12V applications.

Lighter. Smaller. Better.
Just ¼ of the weight of a traditional sealed lead acid batteries. Our 12V Lithium Polymer battery packs will easily fit in a coat pocket or clip to your belt. Gone are the days of carrying heavy lead-acid batteries. You won't believe the difference!
Lightweight
Flat Discharge - Brighter for longer
Lithium polymer technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance.
Discharge Graph
Built in Fuel Gauge
With the built in Tracer fuel gauge you can check the power level remaining in the battery. A touch of the button shows how much energy remains and whether you need to recharge.
Fuel Gauge
High Efficiency Smart Charger
The compact 1.6A Smart Charger (included) will charge your battery quickly.
A rapid 3A charger is available as an optional upgrade.

Smart Charger
Universal Connections Available
Tracer battery packs can power any 12V application. As standard we provide connectors to supply Tracer lighting products and also a 12V cigar socket adapter. (Ideal for mobile phone car chargers or portable DVDs).
In addition we can provide any connection on a bespoke basis. Just call us and ask.

Price PromiseLithium Polymer diagram 12V 8Ah
We offer a range of batteries that have a nominal 12V rating from 4Ah to 22Ah in 5 sizes. This chemical construction produces a battery that is the most compact and lightest available. A five LED fuel gauge keeps the user informed of the battery charge state.

They are most suitable for portable solutions such as powering high power lights, but we supply batteries for many other applications such as security, photography, smart phone charging etc. Maximum continuous current is 10A for all models except the 4A version which will deliver 4A continuous current. Each battery is supplied with an AC mains charger and a 12V vehicle charger.

An internal battery management system (BMS) provides protection in use. All batteries are CE approved and tested to EN38.3 which is the standard for transportation. The batteries are guaranteed for 12 months and will typically give 300 cycles in normal use.

In the box you get the battery, nylon case, cigarette lighter adaptor, power cable and mains charger!

Absolutely perfect power supply.
01 January 2020  | 

I had already decided I would need a power pack for the Celestron CPC1100 I bought from RVO but had been thinking of a different manufacturer before placing my order, but I was given some great advice from the team at RVO so purchased the Tracer 12V 14Ah power pack. It arrived on time from RVO and it is well made, light and just needed to be charged FULLY before it could be put into use. So, in use with the CPC- its small and light and with its neoprene case, attached to the arm of the scope (you need to find your own strap) allowing no dangling power cables and its a case of turning the scope on!. So how long does it last?- well I have used it every night it was clear since receiving it and after 4 hours continuous use of moving to different targets, it only took 15-20 minutes to fully recharge and the built in power gauge always showed nearly fully charged. So a few nights away is definitely going to be no problem for this power pack. It also gets rid of the cord wrap or catch problem with a mains supply.

Zygo Interferometer Testing For ED Refractor Telescopes!

We are extremely pleased to announce our Zygo Interferometer is now installed and ready for use! Our experienced staff can test refractor lenses up to 120mm aperture and provide a comprehensive 2 page report showing the optical quality and Strehl ratio, plus much more information. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.

 

The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. 

We are offering certain telescopes with a Zygo test at an extra cost. Mainly ED doublets and triplets. All available telescopes with a Zygo test report are listed here. Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. This will show you the optical quality of your telescope optics. We can also offer this service on your refractor telescope. Please get in touch for more details about this. 

At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope.  We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. 

Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.

We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface. 

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 

Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. 

All available telescopes are on the website at the link below and ones we've tested already that are available straight away are also listed.

Here is an example of the test what we provide. This was a test on one of our Horizon 60 ED OTA's.
