Back when NiMH and NiCad ruled the battery market, you knew what kind of cells you were buying. Sanyo and Panasonic were the two main cell manufacturers, and anyone selling batteries obtained them from those two sources. NiMH and NiCad had characteristics that you could use to your advantage or disadvantage, but you knew what you were getting.

LiPo batteries have changed the market, often for the better but sometimes, not so much. Their run time, power, and price have all been great for the hobby, but a drawback is that you don't know who made the cells inside that black case. This isn't necessarily terrible, but as a consumer, I'd like to know who makes what I'm buying- mostly because if the battery isn't good, I don't want to buy it again from a different company that has only rebranded it.

Gens Ace is a battery company that you have probably used in one form or another. They manufacture and sell batteries, so the odds are pretty good that you have used some of them that have a different logo. In my experience, there are two kinds of batteries: first are the cheap LiPos that are low capacity and have low C-ratings, that power many RTRs. You'll know them when you pick them up because they are ultra light and feel "cheap," even though they're much better than cheap NiMH packs. The second level is where the power comes from. These are the packs that power racecars and high-performance planes and boats. You pay more for these packs and, for the most part, they're worth the cash.


We got two of their new 100C, 6000mAh packs, which is enough power for any modified class, and then some. Lots of times we use fewer milliamps to reduce the overall weight of the pack, but if you're strapping these packs into a basher, you just want power and run time.

Let's be real about testing batteries: unless they blow up the first day, there is no real way to quantify which pack is better. Many things affect their power delivery, it's hard to see a difference at this level. So we charged the packs at the highest rate our Hitec charger could push, and the battery balanced perfectly. It's the standard race-pack size, but we did notice it doesn't have a "ROAR approved" sticker like some companies put on there. Don't worry, though; this one is on the ROAR list for approved batteries. If you don't know what ROAR is, then you don't have to worry at all.

For testing, we stuck a single pack in our B6.1 for some laps, and to no one's surprise, the battery performed like every other race pack we had for testing. Our second test was a little more intense, as we put two in our Pro-Line PRO-MT 4x4 and cranked the power up to 4S levels. Again, no issues; the batteries provided insane rip off the line and didn't seem to have any temperature issues. We always recommend balancing packs, and it's even more critical to have your voltage cutoff on the ESC set properly to make sure that you have no issues.


Today's LiPo market is huge, and the choices are even more so. If you asked us what advantage Gens Ace has over the name brands, here in the USA, it's price. We found this pack for $82 everywhere we looked, and compared with other race brand offerings, that's about $20 to $30 cheaper. Of course, only you can decide if saving $30 and not having the race sticker on your vehicle is worth it. We look at it like this: if you buy 3 packs, you basically can get a 4th for free. That's worth thinking about. and if you want to look for it in Europe, here is Gens ace 6000 2s.
