Adventurer's Best Friend, Solar Panel Battery Chargers

Some people are serious adventurers are going for solar panel battery chargers. Whether it is camping in the outback for weeks at a time, hiking some of the roughest terrains in the world, or just getting up in the high country to get in touch with nature, they take everything they can pack in a backpack, and rely on their skills to get them through weeks or more in the wilderness.

However, these people still enjoy their electronic devices, whether it is an I-Pod to listen to their music, a lap top to do some writing, or a cell phone for emergencies. The problem is that these devices all have batteries, and need to either be recharged, or they don't last very long. There is hope though for the serious adventurer.

These panels aren't your regular run of the mill solar chargers either. They are extremely rugged, and can hold up to the harshest of conditions. They use the latest in mono-crystalline technology, and are efficient even in cloudy conditions. Each set of eight panels can provide 27 watts of solar power, yet fold up into a small compact size that can fit just about anywhere. They are water resistant, come with a variety of adapter cords, and include rod supports to keep them rigid while charging, and grommets for many hanging options.

Now you can buy there solar products separately, the panels, the power packs, lights and convertor, but if you want to save money, there are also combination kits for the serious explorer, the 120, and the 50. Both of these combination kits are good, and which one you purchase depends on your individual needs.

The Sherpa 120 Adventure kit is the power house kit. It comes with the Nomad 27 solar panel, as described earlier. It also comes with the Sherpa 120 power pack, which stores 120 watt hours of energy, weighs just 3.8 pounds, and has built in USB and DC ports for charging a variety of hand held devices. It is equivalent to 70,000 AA batteries. This power pack can be charged in 2.5 hours with a standard household outlet, or in just 8 hours with the Nomad panel. This kit also comes with the Sherpa universal inverter, wall plug, female as well as male DC plugs, and the carrying case.

The Sherpa 50 includes a 13.5 watt Nomad solar panel, the Sherpa Fifty power pack with 50 watt hours of continuous power that can be charged either with a wall socket, or the solar panel. It doesn't include the universal adapter. The Sherpa fifty can replace 30,000 AA batteries. You can also get many more combinations, depending on your needs, from the Base Camp kit, the Ranger kit, and many others.

These are just a few of the solar panel battery chargers and kits on the market, you can find more at many retailers. But one thing to keep in mind is that when you choose any solar battery pack for a camping or hiking trip, be sure it can withstand harsh conditions. You do not want to buy something that will burn out in a couple days when you plan to be gone for a couple weeks.

How do you increase the voltage for a 7.2 rechargable battery pack?

hey guys. I have a toy Lamborghini Gallardo car, and it has a 7.2V Rechargable Ni-Cd battery pack. what i want to do it add an extra AA battery do hopefully give it more power. what i need to know is, what connects the all the batteries with the wire that you plug in to the other wire that connects to the car and the battery charger? whats on the batteries that conducts the electric charge to all 6 AA batteries?

No, you shouldn't do this. Cells in series should always be the same type and mAh rating. Otherwise one cell will discharge before the others and will end up being reverse-charged. That cell is then dead.

You're referring to NiCd "memory effect." It's a myth for consumer-sized cells. It was only ever seen in very large sintered-plate cells, and then only if the cells were repeatedly - and I mean hundreds of times - discharged to within a few percentage points of the same level. (It originally showed up in a satellite, where the cells were discharged only while the sat was in the Earth's shadow - which was the same duration within a few minutes from one day to the next.)

Furthermore, "full" discharge is NOT required to avoid memory. All that is required is to discharge the pack to a substantially different level each time. It is also avoided by a smart charger that achieves the correct state of "overcharge" (not the same as excess charging, see next paragraph) at the end of the charge cycle.

What was commonly seen in consumer apps was a different phenomenon called "voltage depression." It is brought on not by incomplete discharge before charging, but rather by excess charging with "dumb" chargers. The instructions with such chargers always said "charge for about 8 hours or overnight" - the chargers had no automatic cutoff; they were just a DC supply at about 1.4V/cell connected in parallel with the pack. But people left these things "on charge" pretty much continuously. This causes "voltage depression," which shows up as loss of runtime.

There is an amusing "intersection" of "not full discharge" with the cause of voltage depression. Again, users were told "charge for 8 hours." But even if they followed that advice... if they started with an incomplete discharge, the "correct" charging time of 8 hours was too long! Causing voltage depression. Not true memory.

With smart chargers (all chargers these days) it just isn't an issue.

And *deep* discharge is not a good thing for NiCds, especially in something like an RC car where there's no circuit to stop the discharge when the pack drops below 1V/cell. Discharging below that point will likely result in one or more cells going into reversal. At that point the pack is toast, unless you are able to take it apart and replace the bad cell. Discharge to below 1V/cell is only safe for NiCds if you can do it to the cells in isolation - NEVER for a series pack of several cells.
