note that the brakes and tyres were garbage.
Mod list - bull horn bars, Tektro brakes calipers (still the wrong size), Shimano SPD mountain pedals, 2 speed sturmey archer rear hub, 1/2 link chain.
new 700x32C slicks with kevlar lining and thorn resistant tubes.
Ebike bits
11.6Ah 48V Samsung pack by EM3EV, 350W 16T MAC and 6 fet controller.
she cruises happily at 40km/h flat no pedaling.
so far little pedaling i get 12.5Wh/km, normal pedaling 7.25Wh/km.
Solar Panel as shown connects directly to the 48V pack no problems, BMS shuts it down when it reaches full charge at 56V or i pull it off at 54V.
Anyone interested its a First Solar FS-382 with 82.5W and VOC of 60V MPP voltage is about 50V hence early in charge cycle pumps in more , as batt voltage rises panel moves away from Max power point and charge current falls off.
at 56V there is only a handful of watts going in hence even if the BMS failed would be difficult to set fire to it
Will post some closer up pics as soon as i get the frame bag to hide all the ugliness of wiring loom.
Bike weight is about 18kg -under 40lbs and with me on it i'm good for 60km+ range at 40km/hr making it a good solution
Whats the price of the whole solar set up?
