Another great cell. This is the larger 21700 size that supports up to 30 amps and a huge capacity.

These high capacity Lithium Ion batteries can handle a whopping 30 amps! Thus allowing them to be used in many high power application such as powering radio gear or any other application where the amp draw is at or under 30 amps.

Liion batteries

Purchased for my Volantex Phoenis S 1600 to do 4Ah 2S. Soldered, charged and works like a charm. Prefer this over the 18650 due to higher Amp draw. Thanks to the higher amp draw good as a 3S for any of my planes. All batteries were charged as they should for storage and all within 0.01 V difference. Quick shipping, good price.
