Review: Great upgrade for the X11C, but extra weight needs some pilot adjustment - The charger works very well, although it does slightly overcharge each battery to about 4.28 volts. The voltage returns to at or just below 4.2 volts after removal from the charger. It charged all 6 batteries from storage charge voltage (3.8 volts) to full charge in < 30minutes using a 2.5 amp USB power cube. Each battery has an individual charge controller, as each LED winked off individually. The unit is well built and great for ultra-portable field use. I have an Imax B6 Mini charger with parallel charging cable I will normally use for these batteries, but having this little charger is a nice plus for backup. I bought the batteries for use in a Syma X11C quadcopter. The batteries are over twice the capacity of the original 250 maH cell. However, they still slide easily into the battery compartment and are almost fully enclosed. Very nice. The extra weight of the battery is well-distributed and affects the trim and balance if the X11C very little. However the flight characteristics are different because of the added mass and inertia. More opposite control is needed to counter movement. Changing to high rates on the remote seems to help. I found I adapted to the added weight after only a few flights. Battery life in the X11C is much longer, although I did not time my flights. Power is greater, but needed to manage the extra weight of the cell. I noticed that on a few cells, the X11C cut off the voltage at a VERY low level, around 2.8 volts. This is far below the recommended 3.3 volts and could cause damage to the cell. However, after a few charge cycles, this no longer happened and the X11C cut off the flight at around 3.3 volts, the normal cutoff voltage. The physical quality of the batteries are excellent. The leads are heavy gauge with quality connectors. Each cell is well wrapped and none of the cells had any puffiness. The physical dimensions are also very consistent. I have parallel charged up to 5 cells at once on my Imax B6 Mini charger with great success. The cell voltage characteristics and internal resistances that I measured are very consistent. A great value. I am very pleased with the purchase. UPDATE: I discovered something interesting. When one of the cells discharged to a very low voltage, I found that the battery appeared to be dead. It would not even register on my voltmeter. However, it accepted a charge just fine. It turns out that these batteries do have a circuit within that protects the battery against over-discharge, short circuits, and excessive charge current. This is a very good safety feature, as dropping the cell below 3 volts can cause permanent damage and a dead short can cause melted plastic or a fire. I have charged the batteries at up to 3C (1.5 amps), but much higher and the current seems to self-limit in the battery, even though the charger is set for a higher current. I would say this is a very good feature. The circuit seems to add very little internal resistance to the cell, so performance is hardly affected.
Review: Must have upgrade for X11! - Bought for use in Syma X11C. First off, these things last a ton longer than the stock battery - I haven't timed any flights but I'm guessing around 10 minutes - and that's flying outside in fast mode. The 6 port charger is great - still a 30-40 minute charge time, but beats the crap out of the single port charger that came with the quad. I did take the time to label the ports and their corresponding LED - helps take the guesswork out of which battery is done charging. The batteries fit into the X11 just fine, but stick out the back a bit more than stock (they are longer, so that's expected). The fit is not as snug as the stock battery, so I've found that after a hard crash or other impacts the battery will slide out a bit, which drastically alters flight - you have to re-insert or you won't be able to fly. Pros: Great upgrade battery for Syma X11 - much longer flight time Can charge 6 batteries at once Black tape at wire/plug connection to prevent wires from pulling out Cons: not a perfect fit - battery will start to slide out after impacts

### ⭐⭐⭐⭐ Mostly a great product
*by B***. on February 23, 2019*

one battery seemed to go bad early on with fairly strict attention to handling, the charger can be fiddly. Overall being able to charge all batteries at once and have multiple batteries charged is essential to those trying to advance their skills. These batteries and a Hubsan X4 H107L or C model or three Make an unbeatable intermediate pilot training package bang for buck. Also runs other quads just fine.
