Spektrum 14.8V 2200mAh 4S 30C Smart LiPo G2: IC3, SPMX224S30, Medium

Love the smart batteries. great if you have telemetry. Definitely go 4S over 3S if your ESC allows.

Great battery life, easy to charge

Holds charge well.

I have 8 or 9 Smart batteries- both 3S and 4S sizes, ranging from 2200mAh to 3200mAh. Most have well over 100 cycles and work great, like they did say one. I usually use them quickly, once charged. But the auto discharge feature has been great when life throws me a curve ball. Having an XBC100 battery and servo tester is a must with these LiPos. They’re programmable and pack a nice punch in my RC planes.If you’re responsible. They’ll reward you with longevity.Highly recommend.

The bigger pack my jet balances perfect has more speed and longer flight times.

I have 2 of these batteries so far and haven't came across any issues whatsoever. I will keep buying these 4S G2 batteries because they have been reliable even the 3S 2200mah batteries in case you're wondering also.

G2 batteries are amazing. No effort required to properly charge or maintain. This makes it easy for people like me who will have time to fly every few days and then get busy and not fly for 2 months. No need to worry about storage maintenance, just store them in a safe place and let the batteries maintain themselves.

Have several of these batteries and all are still over 96% after many charge cycles.......not had one fail on me yet.
