Lithium Ion regulated power supply
for Minelab SD GP detectors

 

Coiltek Lithium Ion battery COILTEK SWITCHABLE LI-ION REGULATED SYSTEM Included in the kit you get the following: 1 x Regulator switchable to 7.3volts or 6.7volts. 1 x Li-Ion batteries 7.2volt 7800mAH 1 x Li-Ion battery charger – 240volt and 12volt car adaptor. 1 x Carry pouch specially designed for system   The price of the complete kit is: $300 RRP including GST     TECHNICAL DETAILS Coiltek have now produced a lightweight, highly efficient regulated system which runs off Li-Ion batteries. The regulator has been designed with minimal losses and has been adapted so the user can switch between voltages for SD’s and GP’s. Each battery weighs around 280 grams and will have a run time of approximately 5 hours. This is dependant on the conditions of prospecting at the time. The more targets the more power drain etc. so it is recommended to run them for about 5 hours each as a maximum. Changing over at lunch time is a good habit to employ. The system, once placed in the pouch provided will only weigh around 450grams total. The second battery (provided) can easily be carried as a spare as it is so light, or left on charge waiting to be used. To change the battery the operator only needs to turn off the regulator and detector and remove the battery from its cradle on the regulator, then place the charged one back on. It’s that easy! In the Regulator kit you get: THE POUCH Li-Ion battery in pouch The carry pouch has a belt clip attached so the operator can clip to the belt of his existing carry pack or anywhere he/she chooses. The pouch could even be attached to the Control Box Cover so the unit and pouch are all in the one close location. We can provide a short power cord if the user wishes to mount their battery system in this manner. The pouch has a Velcro flip-lid which holds the battery in tight and also provides protection as it is padded. There is a hole on the under side where the power cable can be attached to the regulator and the flip-lid has a cut away section so it is easy to see the LED indicator for battery level. The pouch is supplied as a convenient carry case for the regulator and one battery attached. The operator can choose whether to use it or not. The unit will easily fit into any backpack pouch or other holders. The main thing is to keep the battery secure to the cradle.     Inserting battery to regulator       Detail of battery voltage switch   Coiltek have used a lightweight ABS case and a compatible cradle for the battery. It uses a low-loss regulator circuit for maximum power and has built in safety fuses and gates for protection in case of a fault. There is a switch which the user can operate to acquire 6.7 or 7.3 volts out of the regulator with a ‘CENTRE OFF’ position so the unit will be turned off before switching to the other voltage. This serves not only as a convenient feature for operators who are lucky enough to have 2 machines (SD and GP) but also add protection when switching voltages. The centre off makes sure the voltage is stopped if the switch is accidentally bumped and moved to a different voltage. Testing showed that even a rapid flick between voltages posed no problems to the regulator or detector. As all users set-and-forget there is no risk of detector or regulator damage. We know of several operators using the higher voltage regulators (Coiltek or other manufacturer’s) with no harm to the GP. There is no point as with the GP the internal regulator prevents this higher voltage providing a larger magnetic field. There is a headphone jack and 4 pin panel mount plug for the power cord connection at either end of the regulator. It is easy to see how the unit is orientated in the pouch. There is also a RED LED indicator light near the switch and headphone jack. This RED LED dims when the Battery power gets to around 7.28 volts ‘raw’ power. The light does not dim constantly from when the unit is turned on, it only dims when it gets to the mentioned voltage. When the indicator light is nearly out or out then it is recommended the battery be charged, even if the unit is still running. A good habit would be to change batteries after around 5 hrs use even if the light is still bright. The indicator light is only there to let you know when the battery is flat and is best to use the 5 hr change rule. There is also a green LED on the battery cradle, this is just to indicate that the battery has power and the Regulator is turned on. Always disconnect the battery from the regulator when not in use.   THE BATTERY Coiltek are using a 7.2volt, 7800 mAH high capacity camcorder battery. The batteries are Li-Ion and already come fully circuit protected. They are an off the shelf unit for the Sony Camcorder which make these batteries easy to replace or source. Having the battery separate from the regulator makes it easy to replace parts if needed. The battery should only be charged on the charger provided in the kit as no other current charger for detectors will charge the batteries. This must be made clear to the user as use of a charger which is not specific for these batteries will do permanent damage to the batteries and is not covered under warranty. Li-Ion batteries have no memory effect so regular charging is OK. They actually perform better if charged regularly and dislike being fully discharged as this will reduce cycle life. Cycle life of the batteries is around 300 cycles. If you are not using the system for a month or more, it is best to store them with a full charge and regularly check their voltage and charge if necessary. Providing the batteries are treated in a proper manner they come with a limited 1 year warranty. Replacement batteries are available through Coiltek. Of course, keep the batteries dry and out of extreme heat conditions like the fire! Li-Ion batteries are volatile if they do not have the proper circuit protection. The batteries we supply are fully tested and safety passed by our battery supplier so the user is 100% safe if they treat them properly. The battery weighs around 292 grams and provide power on a SD or GP detector for around 7.5 hrs. This time can vary depending on the amount of targets and conditions which are experienced by the operator. It is recommended the operator have a multi-meter handy to keep a check on the batteries power. A fully charged battery will read around 8.4volts, a fully discharged battery will read around 7.2 volts. THE CHARGER The charger supplied is to be used for the batteries supplied only and will not charge SLA or Ni-MH batteries. It can accept 12 volts from the car or 240 volts from a wall outlet. The charger has a USA style pin configuration but comes supplied with an adaptor so it can be plugged into an Australian wall outlet. For future kits the charger may vary. The charger has a LED indicator which is GREEN when power is supplied to the unit. When a battery is attached and is lower than the required charged voltage the light will go RED and charging commences. Depending on the voltage level of the battery, the charger can take anywhere between 1 hour to 6 hrs to charge a flat battery. This also depends on the capacity of the battery. This time is only a rough guide and the operator should provide adequate time for charging. Once the GREEN LED comes on it is recommended to leave the battery on the charger for another half an hour to complete the trickle charge cycle, however it is not essential. It would be wise to do this every 4 or 5 charge cycles to fully regenerate the battery. Before connecting a battery, always make sure there is power to the charger first. Do not force the battery on the charger it should go on with ease. If no lights are seen, disconnect the charger and inspect equipment or power source. Always disconnect the battery from the charger when not in use. THE SYSTEM Coiltek Li-Ion battery available now ! The operator is to use common sense when using this system in rough terrain or weather. If overgrown bush-land is to be encountered, extra care is needed to protect your investment. By securing the system in a backpack or locating the unit in a safe place minimal damage will occur. Same goes for any piece of your equipment as in curly cords, headphone jack and leads and also coil leads and plugs. The unit is also not water resistant or proof so if wet whether is due think twice about detecting. Any damage to the unit cause by an operator is not covered under warranty. The Coiltek Regulated System comes with a limited 1 year warranty which is held by Coiltek Adelaide. This warranty starts from date of purchase and receipt of purchase or warranty card must be submitted when a claim is made. The warranty covers manufacturing faults only and if you feel something is not right do not hesitate to contact Coiltek immediately for prompt action.
