"The magic happens when #pedaling #generates energy, which is then stored in the #supercapacitor, allowing for a rapid #recharge of the system. This #stored #energy can be unleashed for tasks like #climbing hills. With the #PI-POP #electricbike, the days of plugging in to recharge are over; your pedaling recharges it."

Any suggestions of safely discharging a supercapacitor bank? I've got a device with two 120 Farad Tecate Ultracapacitors (rated 2.7 V) that are sitting about 85% full.

I'd really rather not wait a week to get these discharged naturally
