Zeee 2S Lipo Battery 7.4V 5200mAh 50C Hard case Battery with 4.0mm Bullet to Deans T Plug for 1/8 and 1/10 Scale Vehicles Car Trucks Boats 2 Pack

Zeee brand was recommended to me via the fb groups/forums as a good quality brand of lipo providers. This is actually my second set of Zeee batteries so i knew it was going to be good quality.The hardcase is well built and sturdy. Wires and plugs are good quality. The batteries come in their own boxes and can be stored away with them if not used.Always remember to dispose them securely as lipos are highly combustible. If keeping for long without use, best is to store them at 75% or so charge (storage charge option if you have a smart charger)These fit my new truck Corally Mammoth perfectly. It's as if the dimensions were custom made for the truck. It performs very well with the battery and although i wasn't using it constantly, it lasted me around 45 mins or so when we went out recently to a local park.I also used the battery with my other truck, Ecx Stadium truck brushless converted, and it goes like stink with these on. Obviously not 3s power but for an 2s battery i'd say it's up there at the top in performance.

Used in my old rc ,lots of run time and power

It OK very powerful and fast changing

Good so far not sure how long they will last
