Infineon Controllers: After our recent shipment vanished in transit, we're still sorting out a situation. Our next batch when it does come will finally have a universal voltage range, so that the same unit can run from 24V to 72V batteries without any need to change resistors on the circuitboard.

eZee batteries: We have had good supply all year of the 3 battery types alluded to above, but the high range 36V 14Ah and standard 36V 9Ah options will be sold out soon, with only the 48V 10Ah battery option remaining. Next shipment from eZee is scheduled to arrive mid-July.
