who's the banana republic now?

(mic drop)

too cheap to buy genuine Yaesu batteries

but I'll spend out the ass to hack together battery packs from 18650 cells and trays. Four trays fit, each with four cells in series, 3.7Vdc each.

the hard part is getting the connectors that mate to the radio. I might just bind all four trays in parallel and wire them out through the charging access and over to the external DC molex. I have those parts already.
