For anyone into RC hobbies or working with LiPo batteries, these adapter cables are super handy to have around! You get 2 pieces in the pack, each featuring an EC5 female plug connector on one end and 4.0mm banana male plugs on the other. The cables use thick 12 AWG silicone wire that's about 10cm long - plenty flexible and durable for most applications. They're specifically designed for bullet port LiPo batteries and work with all LiPo chargers that accept JST-XH balance plugs. The other ends have both 4mm and 2mm banana plugs that fit right into your 2S lipo hard-case battery setups. What's really useful is they include the 2S balance wire with JST-XH plug, so you've got everything you need for proper battery management. The silicone insulation can handle higher temperatures and is more resistant to cracking than regular PVC wires. These adapters make it much easier to connect different components in your RC or electronic projects without having to modify your existing setup. Whether you're building drones, RC cars, or any project involving LiPo batteries, having the right adapters saves so much time and frustration. The quality feels solid, and having two means you can set up multiple configurations or keep a spare on hand.
