4S Lipo Battery EC5 14.8V 7500mAh Hardcase 2 Packs for RC Truck Boat | 4S 14.8V 7500mAh Hardcase Lipo Battery Pack 100C EC5 Connector for 1/5 1/6 1/7 RC Car Buggy Boat Airplane 2 packs included

only a couple charges to the set so far but they seem good and balanced. These are a very tight fit for the xmaxx and will not fit the Maxx fyi. I had to remove the padding out of the battery tray to make them fit the xmaxx. The price is amazing for 2 four S lipo batteries of this size.

Everyone will tell you the battery is good but hopefully this little tid bit helps. If you have an orange ic5 plug that spectrum tries to make proprietary so you have to buy the ridiculous priced "smart" batteries. These plug in perfectly fine. Just make sure your charging with a quality ballance charger. I have not charged mine yet because they just arrived and I will not use them right away but I did verify each battery has 4 good cells that are all at appropriate voltage. Hope this review helps those who need more than just a "battery works good" review.

Good batteries for a good price. I really like the run time in getting from these battery s

Bought mine for a Tekno MT410 build, and these are great packs for the price!! I have way more expensive packs, and I'll definitely grab more of these over those, just because these work just as good or better! With excellent run time too! Also includes a pair of Traxxas to EC5 adapters that worked perfectly with my Arrma Kratons Spectrum ESC plug to Traxxas battery plug!

Love this brand. Great longevity for driving and storage. Hard to beat this brand. Hardcastle that fits into almost all battery boxes without any modification.

My 5000 batteries have better run time than these 6500s. I would not recommend buying!!

Have bought different brands an they might last longer .but the price makes up for a few less running time.my 3rd set an haven't had a problem in x maxx.rustler.horizon amp mt.hyper go 3s buggies an also in volantrex sr65 speed boat.an I can't complain about this brand of battery.

I use these in my Xmaxx have had them for several months still charging and discharging just fine.

Well worth the money seems like any other label I've ever used

They work ok. Definitely don’t putout what they claimed. Not the best on high drain rc’s like boats.

Batteries are very heavy. When put onto a smart charger with an LCD screen they only rate 5000mah & not the 7500 that they claim. In a ARRMA Typhon BLX 6s V5, going full tilt, they only last for 6 minutes. There are much better cheap batteries out there. Save your money and do not buy this brand.
