transmitter batteries
hello everyone im needing to replace my transmitter batteries. the manual say to use 9.6v 600 mah. can i use 9.6v 2500mah. i know nothing about batteries
|
If it will fit in the case it won't be a problem. 9.6 volts is 9.6 volts, A 2500 mah pack can produce more amperage than a 600mah pack but that's not an issue as the transmitter will only draw a specific amount and no more(unless there is a problem like an electrical short inside). So a 2500 mah pack will run longer between charges than the 600.

Yes. If the voltage is the same you are good to go. It does not matter how large the battery is if the voltage is correct - it will just run longer.
|
just make sure you have you have the right charger sounds like you went from a a NiCad to NiMH to get the big increase in miliamps martin

You can also use a LiFe battery.
DO NOT use a Lipo battery. There is a big difference, I have a burned out transmitter that used a lipo, voltage is just too high. bo |
If the new one will fit in the case you can use it. If the new one is one of the more exotic chemistry cells then you will want to use the appropriate charger. The simple wall wart style charger can only be used with nickel cadmium or nickel metal hydride.
Anything with lithium as part of the chemical system needs to use a fancy charger to allow proper charging without damage to the pack. Assuming that this is a Nimh pack and again assuming that you want to use the old wall wart charger that came with the set keep in mind that it was set up to charge up a 600mah pack overnight. So the charge rate will be too low to charge a 2500mah pack to full charge in that same amount of time. Instead you'll want to leave the charger connected for a good 48 hours at a time to ensure you get up to somewhere close to a full charge. |
Good point.
You MUST use a proper LiFe charger. |
All that matters are the batteries are the same size and you end up with the same voltage. I just put a 2500 mAh battery in my Devo 10. It's actually smaller than the 8-cell battery holder that comes with the transmitter.
So yes, you can. Just make sure you have a charger that can actually charge a battery with that much capacity. A wall-wart that comes with any radio will take ages to fully charge that pack. |

Yes a 3S Lipo burned out a component in my Futaba 8U Tx.
Tony at 'Radio South' was able to repair it. |
Also remember that if you use a LiFe, besides a charger that will charge LiFe batteries, make sure it will do a balanced charge. Even though it's a 2-cell battery, like a LiPo, it still should be properly balanced charged.

also - if you do use a LiFe or LiPo battery, don't do something stupid like I did and leave your TX on. Over discharging a lithium battery can ruin it.
