EcoPower "Electron" 2S 30C Hard Case LiPo Battery (7.4V/5000mAh) (ROAR Approved)
This is a good battery Seems to be very tough. Break it in, and it will last. I run it in a hpi blitz and have had alot of problems with other brands breaking soldier conection inside the case this battery has held up very well and have more ordered. It may not put out the most power but is very consistent and after a lot of cycles still has good cell v.

mine holds 5600

i did break it in properly by running about half charge the first 5-7 runs

i accidentally drained it completely and it survived! was way under 3.0v per cell but i did recharge it quickly...

great battery at a great price....i might have to grab another

Sorry to say in this case, you get what you pay for. I have had several of these batteries have the cases split due to the expansion of the multiple cells inside the cases. Sadly they only have a 90 day warranty, so I'm out the cost of two of them. Luckily one was still covered and they are sending my a replacement from Amain. Nice folks. In reading up on the vulnerability of this type of battery to catastrophic failure, I think I will just have to suck it up and invest in their Pro-Tech line next time.

Sometimes economy does not turn out to be so economical.

batteries start out great and I have multiple batteries (12) and now they are really going down hill in a hurry, puffing and not taking full charges.

Bought two of these batteries and have been running them in my losi SCTE2.0 with Tekin Pro4 HD 4300 motor at my local track (IERC) which is an indoor clay track. I can get about 9mins of run time before hitting 80% capacity. Pretty good battery for the price and works well on my local indoor track. I have not used it yet on a more open outdoor style track yet. Worth the money if you a local guy looking to have fun at your local track.

I have two of these batteries and i have had them for about three months. They were very good batteries initially, but after 30-40 cycles they have lost quite a bit of performance compared to new. The hard case is nice and the price is very hard to beat. They do still function, but their capacity is down to 4300 on one, and 45-4700 on the other. You get what you pay for. This is a very cheaply priced battery that performs decent enough for bashing. My stock Traxxas 5000mah 2s is very similar in "punch", but lasts 4-5 min longer after they have all been cycled about the same number of times. Overall, buy them for the price until you can save up to buy higher quality, more consistent batteries.

First glance..these are a good buy... inexpensive and work well in most applications... a word to the wise.... do not charge too fast, or quick charge... battery life suffers.. I have several of these in different applications, and so far I have only lost one to swelling in about a year...I haven't had very many expensive batteries for any serious comparison. These are a great beginner's battery and for those who just mess around, yet I suggest a higher discharge rate for serious racing.

Great Batteries, although not quite the quality of Maxamps still a very very nice buy for the money. I bought 4 of these. So far, I still have 3 (one puffed so I discarded). Not bad for the price will be purchasing another.

I have had this battery for a couple of months and it was great for the first ten runs... But it only last about 10-20 minutes now. My turnigy 3000 mah last longer than them. But for the price there not too bad
