I have a JR Sport SX600. It takes a 600mAh Ni-Cd battery. Me and my club members thinks that the battery has a bad cell. I can only go a couple of hours of flying. It will drop a whole volt during a flight. Can I change to a bigger battery or do I need to just stick with the 600mAh battery? and where is the best place to go?


Thanks Brian

Use a higher Mah battery if you like

Yep, pick up a 2300Mah NiMh from one of the Ebay sellers. You won't be disapointed. The only thing you have to watch is over charging them. And don't use a high amp charger, the wall wart that came with your TX is just what you need. Caculate the time need and set an alarm clock to check it then. Some of the NiMh chargers have a thermal sensor, and as long as you dont over heat one, you are good to go. I have one in both my Futaba 9Scap and my 10C. It's great because you can charge one up full and then forget about it for a couple weeks and when you get to the field, you still have about three times the capacity that your stock battery had new. Cost wise, they will be less than an exact replacement by maybe as much as 1/2 the cost.

I use a 1650 MAH NiMh battery in one of my transmitters

watch the connector,the jr tx I have use a jr specific connector to th tx.

If I get a higher mAh battery, will my simple charger that came with the tx work ok?

depeds on what you consider ok......in a perfect word....If it took you 15 hours to charge a 600 mAh battery with your wall wart charger......you step up tp a 1200 mAh battery then it will take 30 hours to charge using the same wall wart charger.......
mAh is just a term to give us an idea of a batteries capacity......so if you hooked up a 600 mA load to a 600 mAh battery. the battery would last an hour ideally.
You can go bigger if you like with longer charge times....but remember when you're battery was new you were ok........Try hobby city,,,cheap with about a 10 day lag time to get your order
