Zeee 4S Lipo Battery 3700mAh 14.8V 60C RC Battery with EC5 Plug for RC Airplane Helicopter RC Boat UAV Drone FPV RC Car Truck Boat(2 Packs)

Great battery for the price

Great performance and value for money

Bought these as I thought I might get some more air time, however despite trying various prop sizes / motors I get pretty much the same ~6minutes flight time with these and the 3300mAh. Well put together batteries balance charge well and certainly have quite a bit of power delivery when needed. Overall I think these are quite good batteries however only time will tell how long they will last.

Fantastic batteries, I use them on my wot4 wood in combination with a 870Kv and a 13x10E prop and I can stay on the air for 10 minutes and have 35% battery left.They are pretty new and they only have boon charge 10 times, we will see with time how quickly they last tho.

Have a set of 4 of these now and no complaints. Just bought another 2. Used in flying fixed wing powered trainer pulling 60A and weighing 2.5kg, I get a good 7mins with 15% left. I'm probably a bit overpropped. Compared to some Radient 5000mAh 4s I've got, these are lighter and take more mAh at point of charge. Either these are great or the Radient are rubbish.

Good product and helpful

Tengo un montón de baterías de esta marca para mis aviones RC y van de lujo. Cargan muy rápido y tienen un rendimiento excelente

Utilisation pour un bateau offshore RC.La qualité semble au rdv.Pas encore utilisé

Pour un avion RC

Unschlagbar in der Preis Leistung.Die Akkus sind hervorragend.

Purtroppo su un aereo modello il peso è importantissimo….. Magari sono delle ottime batterie ma con queste pessime informazioni di fabbrica pessimo acquisto
