Gens Ace Redline 4S LiHV LiPo Battery 130C w/5mm Bullets (15.2V/6000mAh)

Excellent batteries. I have 3 of them I use frequently for 1/8 buggy racing/practice, and all of them have had similar internal resistance (about 4 milliohm per cell, give or take 3 milliohm). I jotted down the resistance readings when brand new, and periodically I'll check them and add to the notes to monitor the health of the batteries, and after 5 months of heavy use, these are still right in line with what they showed when new. I don't like how expensive they are, and you might get the same results with a much cheaper no-name battery for all I know, but these are solid. Since I only charge at 1C max (usually less if I'm not pressed for time), I expect to get 2-3 years or more out of these. Meanwhile, all my friends at the track charge batteries at whatever their chargers max out at, then puff up batteries at the 6 month mark and claim "that's normal battery life for racing." I storage charge mine if I don't expect to get to run in the next 2 days, and this has worked for me so far.

Very good bang for the buck. Has a lot of punch and I haven't noticed any fade all the way to the low voltage cutoff. I picked this pack for the amount of capacity and the price compared to the protek options which I was planning to get and I am happy with my choice. Im not a racer so having the best you can buy isn't my priority.

Great buy! Price was right. I’ve raced this battery several times in my 1/8 scale, works as it should.

Great battery lots of power! 1st real race with them will be tomorrow I can't wait!

After 3 months of club racing. 1 cell went bad.
I wonder if they can replace it .

Love this battery so far it seems to be well built I been running it for two months and I swear the battery looks brand new and the cells balance out evenly I’ll

WOW....just a great battery with excess punch and power. Using in a tekno EB48.4. NO fade, just power. Just as good as other big name brands if not better.

This battery has good performance, so far I would recommend it.

3 runs bad cell returning. .........................

Battery showed up dead. Cells 1&2 showing good voltage. Cell 3 doesn't even register, and Cell 4 shows 0 Volts. Going to try to exchange maybe for ProteK.

I’ve been running these in my new Tenno EB 48 2.0 and they are working great. The man at Thornhill raceway turned me on to these and I think they are great.

Internal resistance is good after one charge. Great packaging

Great battery so far. I was a little turned off with Gens ace reg chemistry batteries puffing for no reason, other than high draw from the ESC? I decided to try one of these due to the low weight and high output. So far the battery has delivered. plenty of punch and runtime, battery is a true 6000ma. I have had 2 practice sessions and a full 2 day event on one battery, and so far it is like new.

So far so good on battery just have a week or so of ownership decent delivery a lil high delivery charge compared to competitors but hopefully Amain has better customer service if needed

Battery ran fine first 3 charges. Now it errors out on my charger something about balance plug. Put the battery into storage mode after the first 3 runs, then I go to charge it for a 4th time (about a week between runs) and it won't charge. I have two of these and one works as it should, the other wont charge... For the money I'll just get 3 chinese specials next time...

Bought 2 of these a month/6 weeks ago and the first has already puffed.

Really disappointed for a battery that costs $130.

Just getting back I to the hobby and got these to go with my ebuggy. They worked well and had no issues. Well constructed and nice finish

I loved these batteries until I had this one go out after 7 charges and the 2s shorty in 8 charges.

These are premium batteries running off of premium esc - never left plugged in - always storage charged.

Very disappointed.

Awesome batteries. I have 3 of these with over 11hrs on each one. They still have good IR ratings and last 20+ minutes in ebuggy. Gens ace is also a great company & stands by their product. Highly quality & highly recommended.

Battery came out of balance so the first cycle needed a very long time to balance out. But since then the battery has been cycled a handful of times and is ok so far. Time will tell.
