Li-Ion Power Tool cells work great for RC!

At my current gearing of 52/14, I should theoretically be able to hit 62 mph, assuming no drivetrain losses. I'm guessing that my actual max. speed would be in the mid-fifties if the batteries can deliver enough amps and volts under load.

I'm seriously considering picking up 2 of these packs and building a 5s2p pack. Would there be any interest for my remaining cells here?

[MetalMan]

Definitely! Except that I don't have the funds for them right now... I'm sure somebody will have some interest.

Well I just bought 2 packs. I'll have 4 cells left over, let me know if anyone is interested in them.

You've got a PM! :)

Just to let everyone know, you can purchase the Emoli cells individually. The one guy that failed at it first was able to acquire them from a source separate from Emoli. What's even better is their price: $14/cell!

This is better than buying an Milwaukee pack and breaking it down!

Ouch, makes me regret buying 2 milwaukee packs oh well.

I got them off ebay for $175 for 2 packs ($12.50 a cell). I have found that these emoli cells can not take a high power draw. I am running a 7XL, MGM 16024 and UE 8 spyder diffs. and on a full throttle start it dies. Once it gets moving decently I can hit full throttle and there is no problem. This gets more noticeable the longer I run it. I am useing 2 2s2p packs.

That's odd. Does it die due to the LVC coming on?

My 9L didn't have that problem at all, but I know it's not pulling as many amps as your 7XL.

Are these cells 3.7v each then?

[Tazz]

cart213, yes it is from the lvc. When it dies I let the trottle go back to neutral (to reset) and I have power again.

Nick, yes the voltage is 3.7v nominal. My two 2s2p packs charge to 8.4v each.

@cart;

the 9L is quite a hot motor!

it can pull serious amps..

[cart213]

Oh, I know it can pull serious amps, I just meant that it shouldn't pull as many amps as a 7XL, right?

[cart213]

Tazz what is your lvc set to? 12 volts is a conservative lvc setting, but if you are hitting the limit with your setup, then you can set it to 10 volts, assuming the Quark has that capability. According to Emoli, the cells are safe down to 2.5 volts each.
