Hi! I have this motor, https://tinyurl.com/y9jojn3z, and this esc, https://tinyurl.com/yd5qlm5n, but I do not know what type of battery to buy. I'm thinking of buying 2 of these, https://tinyurl.com/yatusry2, or these, https://tinyurl.com/ycvc9oyq, and solder them together. Is it a good buy and whats best?
Grateful with an explanation why one is better than the other, thanks!
