There's also a magnetic breakaway connector that you can purchase for the CTEK. So if you drive away and forgot to disconnect the tender cable, this mag connector simply falls away. Finding a good place to mount the mag connector is the tricky part, I started looking but never got around to it on the NSX, and then switched to an Anti-Gravity lithium-ion battery with ReStart so no longer needed the tender. But here it is on my Lotus, just so you get the idea of what it does, it's held to the rear license plate screws with a 3D printed holder, as the battery in in the boot directly behind the taillight. You can purchase the whole kit here (Lotus parts site): https://hethelsport.com/tools/charger-connection-kit/
