The New COILTEK Lithium Ion Pocket Rocket

14 OUNCES of lightweight, non-fluctuating power for your GP or SD.

DITCH the Heavy Lead Acid Battery you have been lugging around for
a HANDFUL of LIGHT WEIGHT POWER!

WHY our MODULAR SYSTEM is better !

If you are looking for a light weight Lithium Ion system you have probably seen some of the other systems on the market.  Sure they're powered by Lithium Ion batteries, and they are light, however, they are integrated into the regulator system.  WHAT's that mean?  That means if you run out of power there is no way to put a full charged battery onto the regulator and continue detecting.  The batteries in these integrated systems are HARD WIRED into the regulator.  The manufacture says this is a plus, since the battery won't "pop off" the regulator.  We give you a pouch to hold the battery securely to the regulator, if you forget to charge a battery with our system just "pop on" your spare battery.  If you forget to charge the battery with their system, well, I guess you just have to sit down and have a good cry.  Price?  Their 14 hour system, with a built in amplifier, $379.95.  Their 4 to 5 hour system is $260.  Having things like a built in amplifier seems to be an attractive feature at first, until something goes wrong and it has to be repaired.  Then the entire system, battery, regulator, amplifier, all have to go back for repair because they are all integrated into one package.

Additionally "their" system is a 12 volt system that has to be regulated down to 7.3 volts or 6.7 volts.  Where does that extra voltage go?  It has to be vented off as heat, and heat and electronics have never been a good combination.  Our system charges to 8.3 volts, and from there we step down to the regulated voltage you need.  The result is, there is literally no heat generated, that is why we are able to use plastic in our components.

COILTEK was the very first company in the market to start marketing regulated power systems.  The first system was a Nickel Metal Hydride battery system with an integrated regulator.  That was when we learned that integrating your battery and regulator was not a smart idea.  MODULAR was the way to go.  The we went to a modular system using a 12 volt lead acid battery and stepping it down with a separate regulator.  The regulator had to be aluminum to act like a giant heat sink to vent off the heat.  AGAIN, not such a good idea, and while we were supplying a non-fluctuating power source, the battery was LEAD ACID and heavy.  We have learned from trial and error.  We know what works and what doesn't and which system is the most user friendly.

WHY MODULAR?  For the same reason they make screw in light bulbs, so when the bulb burns out you can just replace it instead of sending the entire lamp back for repair.

Here's what comes in this amazing package

• TWO (2) 7800 mAh Batteries (1 battery lasts 6 hours minimum)

• ONE Switchable regulator, 6.7 volt for GP or 7.3 for SD series machines.

• AC / DC Charger, so you can charge in your car or at home.

• Cordura Nylon Carry Pouch, attach it to your belt or detector.

Put your regulator and battery in the supplied pouch, and then slip the system into your
Minelab battery pouch with your spare battery.  It takes a whole 10 seconds to slip one battery off the regulator and put the spare on.

Works with you existing power cord and headphones.

Or, if you prefer, order a short power cord and mount the battery system right on the side of your
detector.  At 14 ounces you won't even notice it's there.

PROCEDURAL NOTES !  PLEASE READ!

The way Lithium Batteries are made today they are perfectly safe to use.  The reason they are so safe is because the batteries use an integrated circuit board inside the battery to prevent overcharging.  The circuit board also has a circuit breaker to prevent a short from causing the battery to malfunction or possibly catch on fire.  Because federal regulations require these safeguards there is no way to work around them, nor should you want to, however, there is one simple procedural adjustment you need to make when operating your machine to insure that you do not trip the circuit breaker inside the battery.  No to worry if you do, because you can reset it in 15 seconds following the simple instructions that I am going to give you.

Here's the simple rule to remember!

ALWAYS LEAVE YOUR DETECTOR ON!

Control whether your detector is on or off by turning the regulator on and off, not the detector.

If you turn your regulator on first, instead of your detector, the power from the battery has nowhere to go.  The internal circuitry and circuit breaker interprets this as a possible fault in the circuit and trips the breaker.

In order to correct this you need to place the battery back on the charger for approximately 15 seconds, this resets the circuit breaker inside the battery and you are ready to go.

I strongly recommend that you buy an additional charger so you can keep one in your car at all times.  Also, because the batteries are so light, I carry the spare battery with me, in case I accidentally turn the regulator on first instead of the battery system and trip the battery.

Many times you actually may be able to get away with turning the regulator on first and then your machine and the battery will not trip, some batteries are more sensitive than others and some metal detectors seem to cause the battery to trip and others do not.  However, just remember to always leave your detector on, and control the on off function with the regulator, and not the detector.

We recommend you use a COILTEK Heavy Duty Curly Power Cord,
or short Power Cord if you want to machine mount the battery.

If you intend to use the power system mounted on the side of your detector, DO NOT under any circumstance wrap your long power cord, around your detector to shorten it up.  Use the special short cord. 

One of our customers burned a diode out of his detector twice, tripped the batteries and burned out a regulator.  Of course he blamed it on the COILTEK battery system.  SOMETHING must be wrong with the battery system, because he had never had any other trouble with the his detector. 

I personally went to this person and took all of my test equipment and a new battery system and a new power cord.  To make a long story short, there was nothing wrong with the battery system, the fault was a very worn power cord that had shorted out.

The reason the power cord shorted out on the Lithium Ion system, and not the regular Minelab battery is because this customer was mounting the Lithium Ion system on his detector and wrapping the worn power cord around the control box.  As long as the cord was straight there was no short.  As soon as he wrapped the cord around the control box, the cable would short out and blow the detector and the power supply.  If he had done the same thing using his Minelab battery, and wrapped the power cord, he would have caused a short as well and burned out his detector.

So the lesson to be learned here is to make sure you are using a power cord that is well maintained and free of shorts.  Use the short lead if you want to mount the Lithium Ion System to the side of your detector.

Additional Battery

There is no reason you should need more than the two batteries that are provided.  In fact I recommend the you mark the batteries 1 and 2 and make sure you rotate them in use.  Lithium Ion batteries love to be used and recharged.  There is no memory effect for Lithium ion batteries so if you use the battery for only an hour do not be fearful of charging the battery back up to top it off.  Always charge the battery back up after charging.  Never store a battery unless you have fully charged it.  Store in a cool and dry location and recharge it every 30 days to keep it topped off.  Just in case you feel you need an extra battery, you can purchase it below.

Additional Charger

We strongly recommend that you consider purchasing an extra charger so you have one at home and in the car.  Or just make sure you keep the charger that comes with your package in the car because it is the only way you can reset the battery if it trips.

Place battery on charger until the red light turns green.  The initial charge may take as long as 24 hours.  After that you can estimate it will take approximately 1 hour of charging for each hour of use.  Some people have reported that the batteries seem to actually charge faster in the car than on AC.

I don't know why you would need an additional regulator, unless you ran over the one you had with your car.  (That wouldn't be covered under your warranty, sorry.)  But in case you do you can purchase it separately.
