Simple, Robust and Powerful: SkyRC BD250 takes the guesswork out of choosing the good-performance battery for your application. It offers maximum of 250 Watts/35 Amps to discharge your battery and will test virtually any battery type or size, any chemistry cells. It's stylish but small with a high-performance cooling system and uses MOSFETS from the well-known IXYS, to make sure it can discharge at 250 watts continuously. #skyrc Reference link:
