Zeee 11.1V 80C 5200mAh 3S Lipo Battery with EC5 Connector Hardcase Battery for 1/5 1/8 1/10 RC Car RC Truck Racing Models(2 Packs)

I use these Zeee batteries in my Arrma Big Rock. They fit almost perfectly and aren't too heavy. I put a little piece of velcro on one end so they fit tightly and don't shift. I haven't timed it but my run times have been great and they balance charge nicely so far. Hopefully, I can get a lot of use out of them. It's hard to determine lifespan from reading reviews because not everyone maintains them correctly so time will tell but so far I would recommend these. 80c seems to be plenty for my Big Rock and 5200mAh gives a nice run time. The hard case, wires, and connectors seem to be good quality too. I'm going to also try the 7200mAh which strangely has slightly smaller dimensions than these, but they are heavier so I'll see if the extra weight is worth the extended run times.

I've bought a few of these zee batteries and never had any problems with them, they balance well, have long run times and pack a punch, I run them in my arrma fury and my Traxxas slash. Worth getting.

I’ll run these batteries on my associated MT 10 and they give it plenty of power. The punch level is extreme and as great power and torque for my RC truck I highly recommend Zeee batteries. They have great longevity and high punch level and they are very inexpensive.

Bought 3 pairs of these for my Arrma Bigrock. They last about 20 minutes going mostly full throttle. Every once in a while one will take forever to charge to storage voltage though. Not sure if its the battery or my charger. Would purchase more though.

Bought lots of these battles in bulk. 2s 4s and 3s to use for bashing. I’m not a racer and don’t need extraordinary batteries. Packaging for all are the same and pretty decently boxed. Compared them in weight to my spektrum 3s batteries 5000 mah and theses 3s batteries 5200 mah seem to be the same weight. Hopefully that will mean they pack the same amount of battery life. Just starting out my season this summer and needed lots of new batteries for the fleet. Haven’t actually used any but they all came in storage charge voltage so that is promising. Will write again after use.
