I have a stock battery comes with my revo, and it doesn't label how many mAh. I have bought another one with same brand, same series, and same size. This label 1200mAh. Is it okay to use both at a same time using a Y connector?
I would have to think so...
Make it idiot-proof and along comes a better idiot
Parallel connector? Yes and enjoy the benefits
It most certainly is. Just make sure they are charged the same amount.
