dusting off old emaxx, need help
I bought an E-max 8 years ago? before lipo batteries. I have since had a couple of boys, got into rc planes and the Emaxx has been collecting dust. I can only get a charge on 2 of the old Nimih packs (they were radio shack batteries), but I know that they were 7.2 volt packs. I know that this is a stupid question, but I really don't understand how to pick the right type of lipo pack. Can anyone help me or at least give me a few ideas on specific lipo's to get? I would prefer a cheaper source such as hobbyking, but I am open to just about anything. I am not looking for a top of the line truck, just something fun to tool around with and have my boys play with.
Thanks in advance.
Jon

Never mind, after more research, I remembered that Lipo's need a low voltage cut off. so I will have to use new nimih batteries.

or you could upgrade to brushless... if the truck is still in pretty good condition why not get something from castle... I just go an E-Revo with a mamba monster and I love it.

You can buy a LVC and then you can use lipos with the stock esc.

I like the alarms better because they monitor each cells voltage, instead of an ESCs built in cutoff since it only knows total pack voltage.

RE: dusting off old emaxx, need help
you can just get a low-voltage-alarm. they only cost $5 each.
i did this on an emaxx i had.
a pair of 2s 5000mah lipos will make your emaxx like a new truck. nimhs could never really put out the kinda power the emaxx wants.
and since you have the earlier emaxx, you have the novak made evx speed control. even tho it says 14.4v on it, it will handle a pair of 2s lipo no problem.
you will want to change the battery plugs to deans(or simillar) the tamiya plugs will just melt.
pair of turnigy 2s 5000mah$55
imax b6 charger$50
pair of LVA's$10-15
And for even more power, you could swap out the twin titan 550 motors for a single titan 775 motor($40)

Thanks again guys, I will probably start with a couple of low voltage alarms, I am a little worried that if my boys drive it, they won't hear, but I will figure something out.

RE: dusting off old emaxx, need help
Do you guys know if the old esc pulls power from the batteries equally? and or would anything work with just one battery? I am thinking about buying one lvc and hoping that the esc pulls rather equal and when it looses one battery it will either totally die, or basically die, thus needing to recharge both batteries. Am I on to something or on something.
Thanks again.
Thanks again.
