Charging LIPO batteries in your car

I tried different chargers in my car and the ISDT SC-608 is the one that worked best. All you need is a cable with a lighter plug on one end and a female XT60 on the other. As of April 2017 you can find this charger for $40 shipped in the US. There may be other chargers that are as good, if so I'd like to know. I have no affiliation with the makers of this one and I paid full price from a regular retailer. This wasn't obvious to me so I hope it's useful to others. If so, please share it!
