If you have the choice, get nimh batteries. You can get batts with more mah's and they will last longer. Plus as stated above they can be recharged without being discharged first with no ill effects. But you'll need a charger for nimh batts to charge them. You could charge them with a nicad charger if you wanted to babysit them and check them with a temp gun. The peak detect is different between nicads and nimh's. A nicad charger will overcharge and possibly ruin a nimh battery. Not to mention it could vent or explode...

I like to discharge my nimh batts also. My race packs I do before every recharge. My rx and tx batts I just do at home before the raceday. During the raceday I will charge the rx batt without discharging it if it starts getting low. But I didn't have any problem getting thru a raceday with the rx batts until I started using digital servos..

If i were to charge my Nimh batt halfway, cut the power and resume charging maybe the next day, will it harm the batteries?

also, how long can the battery last not being charged or used after a charge?

Again, you don't need a special charger if you slow charge. Partial charges are okay if you don't have time to fully charge. You can leave a wall charger on for days at a time and you won't overcharge. If you are going to store you car for an extended period, a partial charge is best. Don't worry so much about the charging. RX and TX batteries are pretty much no brainers. Plug in the night before and youre all set.

How many mah's do the batteries you guys use have? I need some knowledge on batteries, i have none as of now. Lets say im looking for 30-1hr run time with the futaba standard s3003 servos, what do i look for in a battery? or if possible if someone doesnt mind, can you just explain all you know about them. Appreciate it

Pretty much any 1200 or 1400 mah reciever battery will do you good and get the runtimes your looking for.

As for radio batteries I got rechargeable nihm's from wallmart (AA for digi cameras). They are like 2200 mah. I can get about two full race days running two classes with them. I think I paid 16 bux or so for eight of them.

If the pack is still good it should last you. I'm running a year old pack of I think 1100's in my gt and it'll go all day. I do like to recharge before the mains just for giggles though. If you're using digital servos they eat up the batts in my opinion. More so in 1/8 scale though has been what I've found.

As big as you can find or afford I imagine. I just got a 1400 mah ofna rx pack to run. But again any 1100 or 1200 batt will probably work well for you. With my 1100 pack in my GT I get a full raceday out of it if I want, I just choose to charge it before the main.

my opinion... discharging is necessary to get the max potential of the battery, but is it that critical for tx and rx packs?

anyway for me, i don't recharge after every run. maybe after 5-6 runs of practice i charge it for the race, halfway during the race before the final, i charge it again.
