I have been using LiPo batteries for three years in my cars which I race on a regular basis. I have never discharged these batteries and have not noticed any degradation by using them without discharge.

I have not heard of or read about any benefit gained by discharging LiPo betteries. If I am misinformed about discharging LiPo batteries, please let me know.

Don't you discharge them everytime you plug them into your car to use?

I think what the poster was trying to say is to NEVER discharge below 3V/cell. You can cycle LiPo packs just like any other but it usually is unnecessary. Balance charge thenm and you're fine. Just use some common sense and a compatible charger.

The nice thing about 12th scale lipos - no balancing needed... Single cell has it's advantages.

REEDY 4600 LIPO 3.7v

Hello I have a question about charging this battery on a ICE charge

Does anyone know how I can charge it at say 6 amps? I can never get the pack to a full charge.

Last time I charged it at home it gave an error about time exceeded and stopped.

So I would like to know how I can increase the amps.

thanks,

Satish

Yeah, technically running the car is discharging the battery, but when the battery starts to fade, it should be shut off as soon as possible. A new user of LiPo batteries should be informed that running the battery until the car stops is not a good thing to do to a LiPo.

So, when is it necessary/beneficial/required to use an appropriate LiPo discharger to drop the voltage to 3 volts?

it has nothing to do with how many amps you are charging at. it has to do with your settings. you should only charge at 1c to avoid really ugly issues. when a lipo charges, it gets to a certain voltage, right at 5v if i remember right. then if you watch it, the current will start dropping untill it hits something like .1 amps. mine shuts i off there. once you reach that peak voltage, the battery is prolly only going to take like a few hundred more milliamps after that, it is essencially full. make sure the capacity is set corectly for the battery.

It is suggested to only charge at 1C, so in this case is would be 4.6A. The CC/CV charging profile raises the charging current to the configured charge current, holds it there until the pack reaches 4.2 v (for 1s), then holds the voltage constant and slowly drops the current until the battery is "full". This usually happens when the current is approximately 0.10 A. It takes a significant amount of time for the current to drop to 0.10 A after the pack reaches the max voltage. As long as you have the time, let it charge all the way.

I charge mine at 6 amps. You have to program the charger to think its a 6000 MhA. Its at the top of the menu- Lipo, 3.7v- 6000Mha
Hope I explained it right.

Satish. Sounds like your charger is hitting a mAh limit or a time limit. I am not familiar with the ICE but there should be an option to increase the mA limit or time limit. If you are charging at 3A lets say, then some chargers will stop charging when 3000mAh has been reached. The charger thinks the battery is 100% full even though the voltage is not to 4.2V.

i use a couple of ices' to charge my batteries, charge them at 1c(4.6 amps in your case.) and at the bottom of the menu options set your charge capacity to 110%, that should get your batteries fully charged, and will help you avoid those messy overcharging messes.

Satich- Hope all is well.
AreCee- Merrrrrrry XMas buddy! Good seeing you/hanging at the IHobby. I'll prolly never be a crawler guy, but you guys did an impressive job. Hope to rub some paint before winters over. How's the Grex treating you? Very impressive tools those guys have.

Default THANKS :)

Just want to say a big thanks to all who pm'd and posted. THink I got this thing down pat.

Only thing setting i am getting mixed comments about is with the Max Charged Capacity setting at the bottom. Some say 50% some 100, 110.

So far I am not having any problems. I check the temp of the lipo regularly, and all is well.

Currently it is set at 6000, charging at 6amps with 50% max charge capacity.

Thanks again everyone, and have a great holiday

Crank that max capacity up to 100% I don't get why they have over 100%? If it's 100%, thats all you get.Don't bother tempting, it'll tell you it's hot. Simultaniously, it'll ignite. These settings are working well for me.

That compressor is sweet. Quiet and pressure on demand. I used it to paint a couple 1/12 bodies and 1/8 buggy bodies.

I found electric 1/8 off-road and love it, got a Hot Bodies Ve8/D8 Tekno Frankenstein but it works. Going to LH Sunday to play in the dirt and Jtec on the first for 1/12.

I still can't race up north for particular reasons I have. Miss big guy, always has been fun racing a gentleman like you.
