Having obtained my second PING battery from China just before Christmas, and having broken it in slowly, I gave the dual PING configuration a test:
(Connected in parallel via ebikes.ca Schottkey diode (no longer available unfortunately))
Location: Fairfield - Victoria B.C., via Galloping Goose trail, Victoria BC, and Prospect Lake Road, Old West Saanich Road, to Sidney, back to Victoria on Lochside
Conditions: 10C, dry, overcast
Total batteries carried: Dual Ping 48 15Ahr, in parallel
Bike: EZ Sport CX recumbent, always pedalled (24 speed bike), Big Apple rear tire, Crystallyte 405 front motor with Marathon Plus tire.
Controller: Crystallyte analog 35 amp controller
Percent of time with human assist/pedaling: 100%
Terrain: mostly flat with about 5 miles of quite hilly terrain. Sections of loose gravel, mostly paved.
Total distance: 49.43 miles
Total Watt hours: 759.9
Average watt hrs/mile: 15.4
Maximum wattage observed on CA (on big hill) 1360
Max speed 31.4 mph Cruising consistently in low to mid 20s
CA Amp limit: 36 amps ................ Max Amps seen: 48.29 (could feel amp limit kick in when max amps overshot the limit).
Lowest voltage: 47.8 Highest voltage: 60.1 with surface charge after charging, 53.2 no surface charge.
End voltage (stationary): 52.3 volts
Beers consumed: 2 "Herman's Dark" with Green salad, burger.
This was a very satisfactory run, as I believe I used just less than half of my total battery capacity, although this could be more than half as the second half would be delivered at a much lower voltage on average, so lets say 65% to be conservative. So my total range would be estimated to be: 76 miles.
Both batteries on average were well below 1C, preserving their health.
An absolutely lovely ride to kick off the new year. The recumbent is very comfortable and you can carry a lot of battery to go easy on them without worrying much about range. I could probably leech about 6 amp hours off the grid on the ferry to Vancouver, so this puts Vancouver well within range, as well as the San Juan Islands, from Victoria.
