Much lighter to carry
It has always been a problem for the guys.Hence, that go out at night in the countryside looking for things to hunt. Usually vermin. This rural activity is often referred to as Lamping Rabbits. The general idea is to stalk the animal say a fox. Consequently, by using a lamp with a strong beam. So is pointed at the animal. Thus, the animal will then freeze in the bright light. The animal is then shot. For this reason, this is usually aimed at vermin. Such as foxes, rats and in some areas rabbits. Hence, that may have a population problem and the numbers need to be culled. The majority of lamping is carried
out by responsible country people, that respect nature and are just doing a job.
The lamp that they use is usually powered by a 7amp UPS battery, the type that is used in backup power systems, but these small lamping batteries are lead acid batteries and therefore start to become very heavy, especially in the dark when you are walking through undergrowth and in hilly woodland. Some lampers also carry a spare battery or two, so they tend to get very heavy.
One of the great things to come to the market in recent times.Is the invention of the Lithium Ion Battery Pack. This was originally invented in America. For use on American military planes. Such as the Stealth bombers and more recently to supply batteries for the Space exploration projects for NASA.
This created a brand new battery technology that did not contain lead or lead acid. The new batteries became much lighter and more powerful, making the situation perfect for use as lamp batteries.
These lamping batteries come in two sizes the 6 ah and the 9ah these batteries are 12 volt batteries and the 9 amp lithium replaces the 18 amp UPS lead acid battery and the 6 amp replaces the 10 amp UPS lead acid battery. These batteries are much more powerful than there lead acid counterpart and are much lighter to carry around. The battery charger is also supplied and must be used with the lithium lamping batteries normal lead acid charger will not work with the lithium battery. The downside will be the initial cost , but the lithium battery comes with a two year manufacturers warranty and is more powerful and will last much longer with an added bonus of been very much lighter to carry, in my opinion the lead acid UPS battery will not have a look in compared with the new battery the lithium battery…
“They’re generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for
lithium-ion batteries. Here is a way to get a perspective on the energy density. A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery. A NiMH (nickel-metal hydride) battery pack can store perhaps 100 watt-hours per kilogram, although 60 to 70 watt-hours might be more typical. A lead-acid battery can store only 25 watt-hours per kilogram. Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium-ion battery can handle”... http://electronics.howstuffworks.com/everyday-tech/lithium-ion-battery.htm
