First the value is hard to beat, four batteries and a charger for ~$15. The batteries had a fairly consistent size measuring in at 24.1-24.3mm wide, 41.5-42.0mm long and 7.3-7.5mm thick. The battery charger gets a little warm, not that bad when charging with a 2.1A port. The charger itself looks fairly durable, but the USB cable to 3/32" (2.5mm) plug is a bit cheep.and flimsy. IMO they should have at least used a cheap flimsy USB to micro USB cable, that way users typically have literally dozens of spares laying around should this one get misplaced or damaged. I typically just toss the cheap ones in a pile and use one of my higher quality spares anyway. I checked the voltages after letting the batteries sit for 2hrs after a charge. I used a Fluke 87 Series III that has recently been calibrated and they were 4.21 - 4.22V. Just a tad high, but not too bad. I haven't done any flight time comparisons as of yet to see if there are possibly any duds, but I haven't notice any significant differences yet.

Had no time to test if the batteries really do change in volume after some charges.Yet their factory size is very good

Le plus grand Accus passé pour mon Zyma X5C i devenir et ce avec le balancier de charge pour tous les 4 Accus. Sur le prix je ne vais pas perdre un mot! C'est vraiment un top Deal et je l'adore.

Every battery works fine, just as the charger. Capacity as declared, can fly for 10 minutes straight in eachine e30 (no camera version). On the photo you can see a comparison of the battery from the set (battery A) with the original e30 cell (on the left). Size is very similar, slighlty thinner and longer, but makes no substantial difference. 10/10 would buy again :p

quite comparable to the slightly bigger 650mAh cells i used before these. therefor the 800mAh specification is doubtful. the smaller size and weight is a definitive plus. the charger is very practical for all 3.7V cells this size. cable is on the weak side and i would advise to use a 2A socket usb connector rather than a 500 mA pc socket. works well with a portable power bank too!
