I have a golf cart powered by a lithium battery that I’d like to be able to use to charge my AC180 in an emergency. The battery bank is listed as 120-amp hours at 56-volts (~6000wh !). The AC180 solar charging port is rated for 60-volts. Can I use the Bluetti “12v/24v Lead-acid Battery Charging Cable for AC60/AC180” to connect directly from the cart’s battery terminals to the AC180? (I measured voltage at those terminals and got 52-volts). Thanks for any advice on this.

It works.
But it’s best to use this method only in emergencies, in case sometimes the golf cart’s battery doesn’t have much charge, and then if you charge the AC180, you may overdischarge the cart’s battery.

Thanks for the info - I’ll get one of those cables and test it to make sure then keep it in my emergency kit. My cart has to have the key on to have voltage where I plan to connect, so the battery gauge will be on when I’m transferring to the BLUETTI.
A follow-up for any that might find this in the future with the same question: works perfectly! My cart is a 2019 Ez-Go RXV ELiTE with twin 56V lithium batteries for a total of 120AH. Bought the Bluetti cable mentioned in the original post and the AC180 charges at 500-watt rate. Connected to the main battery terminals on the cart which requires the key to be on to be hot.
