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)

Long lasting product

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.

After 4 years, many runs and hard bashing sessions, the batteries are starting to give up the juice a little early. I run them in a Arrma Granite that I jump and a Arrma Infraction that roasts tires. I will buy another pair of Zees, probably with a higher C rating.

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.

Good price/durability Have about 5 pairs of these and bash the hell out of them. Last about 2 years for me and then they randomly puff up or loose a cell. Keep in mind I am really really hard on these batteries
