Equipment used: SkyRC B6 Mini (genuine) Batteries: Eachine QX95 QX90 E30 E30W Syma X5-15 X5C X5SW-1 H5C 1 To 4 3.7V 600MAH Upgrade Battery Procedure: After receiving a new set of four batteries, I charged each of them to 4.2v using the B6. All batteries came with around 3.8v of charge which is normal for long term storage. Once fully charged, I numbered each battery, #1 through #4, and ran them through a discharge and charge cycle on the B6. All four batteries were discharged, then all batteries were recharged in the same order to allow the battery rest between tests. All batteries appear identical. No markings under the outer blue labels to indicate their capacities. Settings: Discharge rate of 1.2A with cutoff of 3.2v Charge rate 0.5A with cutoff of 4.2v From full charge: Discharge / Charge (in mAh) Battery 1: 620 / 663 Battery 2: 296 / 312 <- Bad Battery 3: 612 / 643 Battery 4: 622 / 656 So, since only 3 out of 4 batteries are usable, it makes a great deal into just an okay deal. Below are the screenshots from the charge cycles. Hope this helps.

Funciona muy bien y lo que te ahorra de tiempo, no tienes que cargarlas una a una y estar pendiente de ello. También dispone de indicadores led que te indican que baterías están cargando y las que ya están cargadas.

I am glad, battery are good and they fit the Eachine E708, original battery was have 550 mAh, but these battery have 600 mAh and time fly is 7-9 min. i recomended this product; good price and quality. short video: https://youtu.be/psQwxxLXSkg

Llegó rápido ,2 semanas. Las baterías son de gran calidad y más capacidad que la original del Syma. Aunque el tamaño es un poco mayor y entran forzando un poco el compartimento. El cargador funciona perfectamente y he cargado las 4 a la vez y a tardado 1 hora en cargarlas. Muy contento con la compra. Gran vendedor y muchas gracias.

Battery pack at a reasonable price. I will use them for a syma x5C. It is very practical the tab that has the battery to extract it from the drone more easily

So far extra flight time is very nice. The ability to charge four at once is great and charges to the correct voltage per my meter. Thanks Banggood, will buy soon!

Gostei do produto, agora estou curtindo ainda muito mais meu drone! Chegou na metade do prazo estimado! Aos meus amigos Brasileiros pode confiar. Parabéns Banggood!!!

A must have for Syma X5C owners, because only one battery from the original X5C runs quickly and needs above an hour to recharge. Works very well. When the batteries are fully charged the red lights shut off, so you know to take them out. Batteries fit in the Syma X5C with a little push in front and then through the battery compartment.

Finally arrived!!Took a long time to receive!!!Worth the wait though!!!Definitely recommended for the chep price and everything seemed to arrive looking good and seems to be charging just fine!!!Nice lil 4 port charger that uses usb plug into wall and the other is a round pin style hook up that goes into charger itself...Happy with purchase and thank you Banggood!!!💯👍🙂

Conclusions: 1) The labelling at 600mAh is JUST acceptable. These cells do deliver 600mAh to a 3V cutoff at a very small 100mA load. The red line. This is about as generous a test as you can do but they do just scrape in. 2) In practical terms they are really a 500mAh cell. At a 1.5Amp load which is a 2.5C rate for a nominal 600mAh cell they have dropped to 3.35V at the 500mAh discharge point. The blue line. 3) They are fairly described as a 5C rate cell, not 25C as on the label. The green line. At 3 Amp continuous discharge they have dropped to 3.5V at 200mAh discharge and barely 3.2V at 500mAh discharge. Allowing for some small voltage drop in the test leads I would be prepared to call these cells 5C - that is 3Amp maximum discharge.
