Not unless you ‘needed’ one with your Nicad setup. Normally, using “battery back-ups” means using parallel packs. You'll need to keep the packs separated for charging and there's always the additional weight to consider, but you get a significant gain in runtime and a whole lot more system security. To keep weight down, you can use a single 5 cell pack with two connector leads fed to two switches to ‘back up’ the radio systems higher risk components.

The lithium-ion battery packs are the same dimensions of the NiMH battery packs, except they are one inch deeper. This means that a Segway i Series equipped with lithium-ion battery packs will have three inches of ground clearance, instead of the four inches available with NiMH.

NiMH and Nicads share the same slow charge requirements.. @ 10% of rated capacity for 14 to 16 hours. Usually, when you upgrade your radio systems packs to NiMH you’ve significantly increased the battery capacity and a new system charger to support the packs in a reasonable time frame is appropriate. NiMH, unlike Nicad CAN be supported at lower charge rates than 10%, but beware.. Nicad packs of greater than 1100ma capacity CANNOT be supported by 50ma OEM wall warts.

Yes, if the connector fits correctly, and your telephone base is designed to charge the new battery’s chemistry. Contact the phone’s manufacturer to determine which chemistries the base is able to charge.

In most cases, a NiMH battery can be used as a direct replacement for a NiCad battery. When doing so, however, the charger must be checked. A NiMH charger can charge a NiCad battery but a charger designed only for the NiCad battery should not be used to charge the NiMH battery. Battery damage may result due to inaccurate full-charge detection and excessive trickle charge while in ready mode. If no alternative exists, the battery should be removed as the green "ready" light appears.

Sure! Just as with Nicads, NiMH packs can be placed into duty cycles wired in parallel as long as they are of the same voltage. However; they need to be charged separately!! Charging in parallel could quite easily damage the cells or worse. Never charge Nicads or NiMH packs in Parallel!

Quality NoBS Sanyo NiMH replacement packs and Computer R/C Transmitters are perfect for each other. The original equipment 700ma Nicad pack in my Futaba 9CAP would peter out in under an hour of operation. With a new NoBS Sanyo NiMH 1650ma replacement the run time is better than twice that; even more when I’m not in PCM mode (4 + hours in PPM!).

No, you can use a newer NiMH charger to charge your old NiCD batteries but you should not try to charge NiMH batteries with a NiCD charger. Here's why: NiMH and NiCD batteries are chemically very similar and when both are fully charged the battery voltage will start to drop. The NiMH voltage drop is much more subtle and more difficult to detect.

Using the batteries to end of life prior to charging is recommended when a timer based charger is used. A smart charger monitors the cell condition during charge and prevents overcharging and subsequent negative impact on battery cycle life.

You probably mean to ask: What is the self discharge rate of a NiMH battery? The rate of self discharge for any battery depends on the temperature at which it's stored. Stored at 70 degrees F (20 C) NiMH batteries will lose up to 40% of their charge within a month. If they are stored at a higher temperature, they will self discharge at an even higher rate. Stored at a lower temperature they self discharge at a lower rate (Self discharge chart available soon).

The main difference between the two is the fact that NiMH batteries (the newer of the two technologies) offer higher energy densities than NiCads. In other words, pound for pound, NiMH delivers approximately twice the capacity of its NiCad counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the "memory effect".

The BCM-1 Battery Charger (Item #260206) for the EVOLT E-510 is rated at 100-240 V AC and automatically adjusts itself for the local electrical current. However, you may have to get a set of plug adapters for the different wall outlets used in foreign countries. Plug adapter kits are available at electronics and luggage stores. The EVOLT E-510 accepts CompactFlash cards up to 8 GB capacity and supports Write Acceleration CompactFlash cards.

You will need vector editing software such as Adobe Illustrator or Corel Draw to use our vector packs. Macromedia Freehand might work, but we aren't guaranteeing anything. Adobe Photoshop will open the vectors, but it will ask you to rasterize them; which may cause trouble if you plan on using the vector packs on really big files. The textures will open in any image editor, they are just JPGs. Brushes are for Photoshop. Fonts are for both MAC and PC.

In far and away the majority of R/C Rx applications a 6v NiMH pack provides the same faster servo speed and increased servo output power a 6v Nicad would without any of the twitches or jitters long associated with Nicad 6v systems. Nicads display a relatively high ‘surface voltage spike’ fresh off of a peak charge, and that’s what’s producing those un-nerving servo jitters.

I suggest that charging at 6 amps for most applications. At times, particularly in modified 5 minute racing or 1/12 scale 8 minute racing, you may need to charge at 5 or 5.5 amps to gain a few seconds of runtime. You'll need to gauge this according to how much runtime you come off of the track with.

Yes. Anytime after the battery test, print the results of the test and keep the prints-outs together. You now have a permanent and dated record of all your battery tests. The UBA software will be able to do this for you.

Type 'N' alkaline batteries are available at drug and camera stores in the USA. The card reader runs them down quickly but otherwise they should have a reasonable lifetime. All types of batteries and rechargeable packs will eventually leak and corrosion is a major killer. Always use fresh cells and remove them when not in use for long periods. Do not store any items in high humidity.

Usually, only the highest-quality batteries are packaged in what is called "6-cell loose packs". These batteries must be soldered together and attached with wires and metal bars. Like saddle packs (above), these batteries are best left for racers and if you're just starting out you don't need to buy these 6-cell loose packs.

The main difference between the two is the fact that NiMH batteries (the newer of the two technologies) offer higher energy densities than NiCad's. In other words, pound for pound, NiMH delivers approximately twice the capacity of its NiCad counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the "memory effect".

The answer is yes and no. If you are using Railsounds with Trainmaster Command Control, then you will not need a battery. With TMCC, track voltage is always present, so no standby source of power is required. However, if you want to occasionally operate the engine in a conventional environment, you will need a 9V battery to provide uninterrupted sounds when you change engine direction by momentarily interrupting the track voltage.

On the first production batch the barrel of the microphone can be unscrewed to reveal a battery compartment with no cables, which is an error by the manufacturer. A battery would not enhance the performance of the microphone and on later batches this has been removed.

You bet, providing the charger MFG’s documentation clearly indicates the peak charge algorithm is appropriate for NiMH packs. Some examples of NiMH safe fast chargers are the current model Multiplex, Hobbico, AstroFlight and the Trition Charger from Great Planes. Programmable Digital Charger / Cyclers generally range in price from $80-150..** but will be able to form charge, fast charge, cycle test and display the capacity info for any battery type your likely to encounter in the hobby.

Certainly! Modern QUALITY NiMH packs are every bit as durable and reliable as any Nicad system. Since their internal impedence in some types can be a stumbling block, using a 5 cell system can overcome the voltage drop associated with bigger bird servo loading. Just as with Nicads, you should select a low impedance cell for your Giant Scale Warbirds and IMAC planes.

Although they have not been known to cause harm, it is best to consult your physician prior to using the heat packs.

Just the latest. For example MOZART Service Pack 4.0.5 will update any of versions 4.0.0, 4.0.1, 4.0.2, 4.0.3, 4.0.4 to 4.0.5 in one step. Note: The free service packs work on the purchased "Virtuoso Edition" only. If you are trying an evaluation copy, an updated evaluation copy is usually made available for download each time a service pack is issued.

Battery packs are more commonly known as Ni-Cads. These are probably the most important part of your car package as they are providing the power to the motor. The best motor in the world will be limited by the ni-cad it is connected to. Prices range from £9.95 for a budget pack through to £60.99, which is the current maximum price permitted for racing. A budget pack is suited for recreational use in a standard car and cannot be expected to perform with an up-rated motor.
