Thats a pretty broad question. Can you narrow it down to an application? Basically its all about knowing how many amps you will be drawing out of the battery. From there just pick a pack based on how light it is, or how much runtime you want. Lipo's really are not dangerous as long as you pay attention to charge and discharge rates. People said NIMH were dangerous when they came out.

Well they are expensive, 3/4 the weight of a nimh with the same number of cells and provide super long runtimes and more power.

well, i am going to be getting either a mini quake or rc18mt, but i have been looking into these lipos quite a bit the last few days, and think that i have learned enough about them to get myself a pretty good start, but if you have any specific lipos in mind, brand and size wise, your help would be appreciated. Also are the lipos used in minis the same as are used for airplanes, ect...?

really it doesnt matter if you get lithium-iron or li-po they both use the same charger and perform basically the same. My brother get about 1 hour-1 and a half hours with lithium, Its great!

Good luck.

i have a 8000 2-cell lipo i run in my MF2, i use it for practice, takes about 45-50 minutes to charge, and i can run it for about 20-30 min with a novak brushless. i pull it off just when i see a small drop in speed, i was told not to run it down all the way or it could damage the pack if you run it dead. i charge it with a duratrax ice charger,

I am not sure exactly which pack fits perfectly. But I would say those trucks are drawing between 10-15 amps. So look for a pack that is around 1500mah or more. And make sure that it has a 10+C discharge rate. All of that info should be listed on the pack. Just find one that fits your truck.

i run my rc18t with a thunderpower 2100 mah 2 cell lithium polymer with a mamba 6800. if you are going to run lithing packs in a rc18mt, you will deffinately want to upgrade to a brushless system, it handles the power better and is faster, go to the 1/18th scale truck tread and i rote alot about how to do the 1/18th scale truck thing the rite way, and if you dont have the money to currently fund a brushless and lipo powered vehicle, save up because there isnot a huge power difference with a bone stock rc18mt with a 6 cell or lipo.just more runtime. www.b-p-p.com has some lipo and brushless products for 1/18's.
