Here is a link to the charger I want, I will pay 20$ for it at Hells survivors 2/21/15. Also if you have one similar that is not the same but will still work, feel free to offer but I have no more than 20$. I need a lipo charger and I don't want to buy a brand new one for more money when I can get a fully functional one used for a little less. Because buying that and then paying for shipping really sucks. www.evike.com/products/30777/

Just a heads up and fair warning. A charger like that will literally take a couple hours to charge any decent size lipo. I have one for my rc helo and it's great for the little 7.4 400mah helo batteries but it takes a good 20-30 minutes to charge.

I am Running a 7.4vt 2000mah battery, and yes I know but I always charge my batteries overnight safely on a smart charger. I just made the switch to a lipo. |

That's a bad and unsafe idea. I know that this is a commerce thread so I really shouldn't be talking, but this needs to be said: Li-Po batteries are very volatile compared to Ni-Cd and Ni-Mh. They can catch fire if treated improperly or if there is a defect with the manufacturing of the battery or charger. If a power surge comes into the outlet while it's charging, the battery could fry and catch fire, explode, etc. Now it's pretty uncommon, but the point is that charging on a smart charger alone is not "safely" charging it. It should be monitored, or at least be stored in a Li-Po fire-containment bag. Don't burn your house down. |

It's also worth noting that the charger you linked to isn't technically a smart charger. Those types of chargers make sure that the battery voltage never exceeds a certain amount across all the cells. For example if you use a 2S lipo it will make sure that both cells combined do not exceed 7.4 volts. That isn't the "smart" way to charge a lipo. If one of your cells discharges faster than the other (common) then that charger will not correct the voltage difference between the packs. It will slowly over charge your strongest cell and under charge your weakest one. I bought a similar charger back in my early days and it killed my 11.1 by allowing the weakest cell to drop eventually to 2 volts when the charge light was green.
If you invest in a lipo, invest in a hobby grade charger. A hobby grade charger will monitor each cell and make sure that they receive a proper balance and a full charge. Your battery will be more powerful and will last longer with a hobby grade charger. You can also put your lipo into storage charge so it doesn't slowly degrade. A really good hobby grade charger will even detect faults in the battery and refuse to charge. I'm not aware of a hobby grade near your price range but some research or a trip to a knowledgeable hobby shop will help you find one. Seriously talk to R/C guys, they love to talk batteries.
If you can't afford a proper charger you would be better off buying an extra 9.6 instead. Do not take a lipo battery lightly. All the safety talk about them may seem obnoxious but people seriously do burn their houses and garages down by being careless with a lipo. Store and charge them in a fire proof container. Keep them at storage voltage and do not over discharge them. NEVER charge them and leave the area or leave them alone overnight.
If any of that seems like too much work, stick with NiMH/NiCd.
I know this is a commerce thread and such, but in the words of Red Forman "You're never too old to burn to death in a fire". Safety first.
