T100 SN002158 vs SN002159 Model

Greetings all, I am working on a school project that involves building an ROV, and my group is reusing some T100 Thrusters, but we have 2 different T100 models: SN002158 and SN002159. We were thinking about ordering more thrusters to match but we don’t know the difference between the 2 models. Are there power differences? The SN002159 has 2 wires coming out from the thruster, but I couldn’t find any posts mentioning this and the SN002158 only has 1 wire. I’ll post pictures below. Any information or specifications on the different models is greatly appreciated, and if there’s a preference, we would also like to hear which is better. Thank you!
