I will be racing the losi 22 2.0 with a tekin rs pro can someone tell me which lipo 2s battery would be the best for my RC I was looking at team orion and trinity and pro tek I seen some bad reviews on protek but no reviews on the others ??

You don't really need to pay for a "big-name" brand like Orion or Trinity. At the same time, you'd be wise to avoid the Chinese un-brands. As well, "best" is highly subjective in the battery world. That being said, for good value and performance, I'd look at SMC and ProMatch.

Another vote for SMC!

I will thanks man

Which one is the most common battery that racers use in 1/10 buggy 2wd racing shorty or saddle pack or reg ????

Yea smc, promatch or SPC, I'm running 2s 6900 100c trinity revtechs and they are very consistent and punchy, got 2 lightly used for 100$ haha couldn't pass that up, next lipo will be a smc

A shorty gives you the most setup options as far as weight distribution goes and in many areas for most cars, is now the "default" 2wd buggy pack.

Wats the difference in a50c lipo to a 100c lipo 2s ???

Price?

I vote for HVR shorty pack. Great price, punch and run time. http://www.electrickrc.com/

Price is not a factor just wat does it mean 50 or 60c or 100c ???

The budget must be nice...

The "C" rating is in effect how fast you can discharge the battery without damaging it. A higher rating is needed on some of the more demanding setups with 4x4 SC running a high KV 4-Pole motor being the most demanding.

I higher C rating also gives a feeling of more punch, as it can simply deliver power at a faster rate. You can also safely charge at a higher rate as you go up in C rating.

Issue is that there is not a standard to measure it. Each manufacturer has way to do it, and one offering 50C might be another manufacturers 60C, and then there are the ones so off the chart high that they must be doing something suspect to cook the numbers.

Personally I suggest a 40C or higher pack as a general rule, and if your budget will allow more I would shop in the 70C + range. For your 22 a good option would the Shorty Packs, saves a good deal of weight, allows you to move the battery more forward or back to change weight distribution... just a good choice in the 22... I just got this set of SMC packs and so far they seem to be a good choice for me. They are on backorder now, but that is because he can not keep up with demand.. just good packs.

Or if epic runtimes are your goal you can get the full sized packs in some very high mAh ratings.

So if I have a 5000mah 100c can I charge it at 6amps ????

That should not be an issue.

Alright cool I'll try it thanks
