[vcf-midatlantic] [OffTopic] - Anderson SB120 to XT60 Female custom cable?

Hey folks, I'm not exceptionally good at soldering and crimping, and was wondering if anyone knew where I could buy custom ready-made cables like the subject here? I have an Ecoflow Delta mini battery, which accepts up to 300W via an XT60 female connector.. While this is normally intended for solar input - any source will do including batteries. (The charge controller specifies 11-75V range, 10A max up to 300W) I also have a Ryobi riding mower which supplies power via 4 x Lead Acid batteries in series (48V), and they output power via an Anderson SB120 connector. I'd like to have the extra capacity for an emergency and looking for recommendations on where to find or ask for a custom cable build like this. Thanks! John
