I run 35 and 45 amp Anderson Power Poles and have had no problem with big amperage use. They are rated at 30 or 45 amps at 120volts so i think they are quite beefy at the 7.4v or 11.1v of a LiPo. I dont even have to solder them on anymore. The crimped method works great and are easy to complete. They snap positively and are a solid connection but still easy to pull apart. They are also worlds cheaper than Deans, TRX or bullets.
