GensAce (Known as Tattu on the air side) has been around for a while and having been involved in regional and national level events in years past, I can assure each person reading this that they were potent cells back in the day, but with limited support stateside. That’s all changed now as GensAce has set up shop in Düsseldorf, Germany and they have revamped their entire lineup of packs. There is an assortment of ROAR approved race packs, from shorties to saddles and everything in between, but some of the hottest cells coming out of the far east via Germany are the basher packs. 

If you’ve got an Arrma or other basher truck that you love to abuse on a daily basis on 6S power, but are concerned about damaging soft case batteries in the vehicle, GensAce has got you covered. They serve up 3S packs in 5000mAh 25C, 5300mAh 50C, and 7000mAh 60C … all with hard case and balance lead retainer.


GensAce hooked me up with a bunch of cells for a wide variety of vehicles, but I had my eyes set of the hard case 3S packs for my Arrma Outcast. I beat the bejesus out of that truck and am always worried about puncturing one of my Onyx 5000mAh packs while running two of them for 6S power, but not anymore. With two hard case packs in there, I was able to cut loose and worry about nothing else other than having a ball with my stunt truck. I did have to swap the factory supplied Deans connectors on the packs for some XT90’s and use a bit of muscle to get both packs stuffed under the telescoping battery cover. A pleasant added benefit was that the GensAce packs also seemed to have a bit more punch than the Onyx packs, even though both are rated at 25C. Sadly, the 5300mAh 50C Hardcase 3S packs from GensAce are too tall to fit into the Outcast. They are only 1mm taller than the 5000’s, but I had to use a shoehorn to get the smaller packs into the beast. The 5300’s do, however, fit into the Nero battery bays with a bit of coercion (stay tuned for a separate write-up on that project). Another nice touch on the hard case packs is that the wires can either be run out the end or up out the top, courtesy of a nice little channel cut into the top corner of each case.

For race duty, I received the new 2S 4200mAh shorty pack for my 2wd buggies, the class that started it all and is still all the rage. I slapped the pack into my AE B6D and took my turf monster out for a tear. With a stated 60C discharge rating, the GensAce shorty packed noticeably more punch than my tired old Trakpower 4400’s that were rated at 50C. With a 17.5 for “Spec” power, I was able to clear sections of jumps previously unattainable. After a good 6 minute run, my motor was only slightly warmer than usual (130 degrees) and I noticed absolutely no fade from the first minute to the last. No, I finally had the power to “double dip” and run my spec buggy in both the Stock and Mod classes at the same event, given the smaller indoor venue. I always wait a while (as you should as well) before juicing the packs back up after running and I always balance charge using my Graupner Polaron EX dual chargers. I can honestly say that all of the new GensAce packs charge and balance with numbers equivalent to much pricier LiPo’s. Less Internal Resistance equals more power and longer life for my batteries … and that is certainly a good thing!

Yes, one can always argue that a battery is just a battery, no matter who you get it from. I’ll just smile and nod as my GensAce powered car blasts past your import powered ride. Seriously though; super cheap prices, awesome construction and attention to detail, stellar performance and an actual 10-digit phone number to call when/if you have any issues with your product. That’s one hell of a convincing list when you’re looking to purchase your next battery. If that isn’t enough, toss in the warranty and rewards points you can accrue from frequent purchases and you’ve got hands down winner for the best bang for your buck in the industry … an industry where there are enough options to make your head spin. Ditch the Excedrin and dial-up GensAce for some serious power.
