- Q: I know that NiMH batteries self-discharge over time, but mine are discharging in just a matter of hours. I am using them in a RC airplane. They are 9.6V 650mah AAA packs. I charge them up just as they should be and they put out full power when I test them in my plane. I go to the gym for a couple hours and stop by the flying field on the way home, but when I plug the battery in the motor on the airplane immediately goes to cut-off.An interesting note: If I hold the arming button down to keep the motor going, eventually it will work itself up to putting out enough power to do some low powered flight and will last the duration over normal flight time for the airplane
- The battery pack is new to you, but it could have been on the shelf in the store or a warehouse for a very long time, easily a couple of years. A single bad cell can ruin a battery pack. 1) One of the cells might have gone bad and can't hold much charge, so it depletes quickly during discharge. The available battery voltage then is 9.6 - 1.2 8.4 volts. As current flows through the bad cell the current reverse-charges the cell, and the available voltage drops to 8.4 - 1.2 7.2 volts. 2) When a motor starts it requires a high current, and this drops the voltage out of the battery due to the internal resistance of the battery. If one cell is bad then the internal resistance is very high. Once the motor is running the required current is less, so the internal resistance of the battery is less, and the battery is able to maintain an adequate voltage. Factories do not test the cells to match their discharge cycles. This can happen to any battery. Car batteries, sealed lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries. extra : This is a huge problem for any large power-storage system, from solar-cell systems to hospitals and server farms. They use large battery banks to give them ride-over time until they can get their gasoline/diesel/natgas generators running. Monitoring each cell in a battery requires special electronics and in the past was not worth the trouble due to the cost. There are now electronic designs that will do this monitoring, but it's not going to be done for cheap RC battery packs.
- Q: I currently need one, so any help would be appreciated.
- You can get rechargeable battery pack and a compact charger at Wal-Mart or almost any big stores. The brand you are looking for is Energizer.
- Q: I have a few cheap LED flashlights that I would like to power with a 7.6 volt R/C car battery pack. I used to power a regular bike light with it, but the bulb was for 7.5 volts. I'd like to go LED for better battery life. All the LED lights use 3 1.5 aaa batteries. Do I need to add anything (resitors, capacitors, etc.), or are they already in there? Any help would be great.
- Your 3 batteries add up to 4.5 volts so you may risk damage to the leds, One method would to add a 5 volt regulator which has 3 tabs--input (where you put the positive lead of the battery, ground, and output which should supply 5 vdc to your leds
- Q: I bought a battery pack for a Game Gear (old sega handheld system) and it came with two parts the wall adapter and the battery pack that it connects to charge it and the charge light won't come on and it was practically new this item was something that was sold years ago is there something wrong with it or do I need to replace the battery part inside if so how do I do that??
- Check the power outlet first, if it is working or not. Then the charger. If it don't light, it is the charger.
- Q: I have an electric scooter with a brand new 24 volt battery pack. When I charge the battery the voltage gets as high as 28 volts or more. I bought a brand new charger that has a 1.8 amp output rating. The charger light stays red while charging and should shut off when it turns green. So far I have not let the charger charge until the green light comes on. I am concerned that I am overcharging the battery. Right now my multimeter reads 28.48 volts. Is this normal? Thanks in advance.
- 28 1/2 volts doesn't worry me; many sealed lead acid batteries charge to more than 2.3 volts per cell. At 29 volts I'd get concerned and at 30 volts I'd call it quits. However, the real issue is whether the batteries are getting hot. If they are just slightly warm they are still converting the energy to chemistry, but if they develop a fever (call it above 110 F) they are just turning the charge into heat they are fully charged.
- Q: I found a battery pack from a few years ago attatched to an remote control car, but cant remember how i used to charge itits one like this
- go to walmart or kmart and buy an rc car battery charger. this type of battery requires a slow charge, that is about 12 hours. there are other, special type batteries, that can be fully recharged in 10 minutes. DO NOT TRY THAT WITH THIS RC BATTERY. just make sure that the charger is for the 9.6v pack.
- Q: Can I upgrade to a 9.6V battery pack? Thanks
- You didn't get 1.2v battery. You received a battery pack made up of 1.2v sub-C cells wired in series Count the cells, if there's 7 1.2v cells then it's a 8.4v battery, if there's 8 1.2v cells, then it's a 9.6v battery.
- Q: I am building an Xbox 360 Laptop, and obviously it can't always be plugged in :P. Where would I be able to find a rechargeable battery to kick out at least 175W, 12V, and 42A (DC current)? Ideas and suggestions are also welcome!
- You will not find one tp fit any machine. this is far too high a load . In act the only batteries capable of this kind of output would be lead acid, as in small car batteries. I don't think they will fit in the case. And can not be safely carried due to acid spillage risks.
- Q: cus i need a few extra dallers n i cant find the battery pack
- They don't take rechargeable battery packs. But you do have to have the original AA battery holder.
- Q: As the title implies, I'm looking to make a battery pack here soon. I have the needed voltage and amperage all lined up, and plan to be using NiMH batteries (either RC battery packs or just some basic AA). But, as the main question ask, I would love to be able to use the battery pack as it is being charged. I'm looking to make a laptop of sorts with a raspberry pi, and would love the battery to act like that of a laptop.Thanks in advance!
- Just use a pair of diodes with the cathodes (band end) to the power regulator for the Pi, one of the diode anodes going to the battery pack output, the other to the charger input jack, which also goes to your charge regulator.
