I am all for buying local and the SMART batteries from Horizon Hobby have a lot of really great features.
But... every once in a while a decent opportunity comes along. This is a 3S 2250mAhr 30C rated LiPo on Amazon - low price of $18.32. I have purchased 4 of these... (I've used 2 thus far) and the results are really great. They also have 4S 2250mAhr 25C on for $23.99 (I have two of these too).
Search on Amazon for "SIGP". https://www.amazon.ca/s?k=sigp&i=toys&ref=nb_sb_noss
