- 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 have a wireless controller that eats up battery'sI'm thinking about buying a charger plug+play thing or whatever it's called but I've heard that after so many charges they really don't do anythingWould it be a waste if money to buy the charger or just keep buying battery's
- No!, i bought a xbox 360 charger thin like that and it works after many charges iv used mine about 30 or 40 times and it works great, so in the long run it would be cheaper to buy the charger!
- Q: differs a lot from the left battery to the right? from left to right, each battery uses successivly less water from a lot to hardly any each time I add water. these are the standard wet batteries exactly the same as those used in fork lifts.
- If I understand your question you have 4 total 6 volt batteries constituting a bank of 4 batteries in series/parallel, which should produce a high capacity 12 volt output. First of all I'm assuming that all of these batteries are in the same circuit and would be subject to the same loading and charging and they are wired correctly. That being the case I would be surprised if there was a great difference between any of the four batteries use of water. It sounds to me like if some of the same batteries are requiring lots of water at whatever interval you are checking there is a problem, especially if one or more of the others aren't. If this is the case my advice would be to contact the battery manufacturer and find out the proper process to equalize all four batteries. If you have one or more of these batteries using excessive water there is a problem. Remember this principal: When using two or more batteries your power is only as good as the weakest battery. That is why you always replace flashlight batteries together with two new ones. It sounds as though one or more of the batteries are sulphating, which will greatly reduce their capacity and generate excess heat boiling off the electrolyte prematurely. Check out my suggestion to equalize the batteries, which if they aren't too far gone will get them all back on equal footing again. Good luck.
- Q: I have a battery pack with an input: D.C. 5V, 2 Amps. I have a tablet-charger with an output: 5.1V, 2.1 A. Can that little difference in Volts and Ampere cause harm to the battery over time? should I look for a 5V/2A charger, or can I use the one I have?Detailed info about the battery and charger:Battery:3.7 V 10 000 mAh/37.0 WhInput: D.C. 5V, 2Aoutput: D.C. 5V, 2.1A + 1 A (two outputs) Charger:input: 100-240V - 0.45A, 50-60Hzoutput: 5.1V, 2.1A
- If the battery pack is lithium-ion, it MUST be charged according to the manufacturer's recommendations to minimize the danger of fire. This requires circuitry that shuts off the charge current if the battery reaches an unsafe temperature, and it MUST terminate charging immediately when the battery is fully charged. If it is NiCd or NiMH, charge it at 0.1 c (10% of its Ah rating) for 14 to 18 hours.
- Q: I have a Fishman Matrix Infinity pickup, the battery pack was held in place by adhesive but has recently come loose. Any ideas for how to re attach it without using a substance that would damage the guitar?
- You can use velcro. They sell both sides and you can cut it to the right fit. If the glue on the back of the vecro isn't strong enough, you can always use your own glue to make it permanent. Its on the inside, so don't sweat it so much.
- Q: I have 3.7V 4000mAh Li-ion cellsI need to connect them in a way to create a battery pack to run a motor of 6000W 60V.I know in need to connect 16 in series to get 60VBut by how much in parallel?Thanks
- If they are 4,000 miliamps, that's 4 amp. You said you need 6,000 watts? That's a lot of juice and money my friend. 60 volts x 25 4 amp batteries would equal the 6000 watt load you need. 25 batteries in parallel, already stacked 16 In a row in series. There are much much better alternatives and cheaper ways of doing this. But if you do decide to, you'll need to know how to run series parallel circuits and keep the wiring even along all batteries with lowest resistance wiring as well to work.
- Q: i need voltages. there are four terminals where the battery goes, im sure one of them is a ground. i just need like a diagram for how i can wire up batteries to it. thanks for any help
- Don't. The batteries for laptops are designed for the job and are carefully matched to the circuitry in the laptop. You stand a good chance of breaking the charging circuitry, or having your homemade battery go up in flames.
- Q: i bought this rechargeable battery pack, and i forgot that it didn't come with a charge cord. any specific name for that charge cord so i can go on OKorder and look it up and buy it? i dont no wut its called so please any answers would be great.
- I dont believe there is any specific charger unless its other than micro soft brand, madcatz, or pelican i think you should be able to buy a charger at game stop but i think it comes with another matching battery pack which would be good if you had 2 controllers.
- Q: And for how long? The continuous power consumption is 12v at 2 amps.
- Your batteries will have to be in SERIES to get the 12 volts. 1.2 volts each X 10 12 volts @ 2 Ahr or 2000 milliamp hours (mah). So in theory, one hour. Reality is that the cells will not actually produce 2 amps for 1 hour without the voltage dropping off. So a rating of about 10% of the capacity is recommended. Your battery pack would work for 5 to 10 minutes before draining them down at 2 amps and would get very hot in the process! Switching to a 12V gel cell or 10 D batteries would be better.
