I'm interested in knowing how well a 408 converts the extra power in the real world, not just the simulator. Also, since we're running the same voltage, we can sort-of compare the 5304 at 72v 35a to its comparably-wound 4xx-series sister, the 408.
Depending on your definition of 'happy', a 20 amp drain-rate is not good enough, IMO.make sure they are happy delivering 20 amps for a good part of the discharge,
This was my thinking with my lithium pack too. Also, having plenty of excess AH's on tap allows me the confidence to go exploring as I ride, without having to plan and map out the entire route. I usually use 10ah or less of my 33ah pack. So I normally charge 80% to 4.0 volts/cell, and run the pack down to 50% or so -- 3.8 volts/cell. This provides about 10ah out of a ~30ah pack in the voltage range lithium cobalt cells are happiest. I'll charge to 4.15v or 4.20v if I'm planning to do some geo-exploringI'm looking at getting batteries that are too large for the distance i'm doing (so that i can get more cycles out of them)
awesome thankyou!Ypedal wrote:The controller will run fine without the Ebrakes conected.. ( I have the same problem on just about every bike out there )
There was a guy making ebrake kits that would hook up to regular integrated setups by glueing a sensor on the underside of the brake levers.. but he's been away for a while.
Good stuff !!!! keep the updates coming !!
cool thanks i've already modified the rear brakes to fit was just worred about the rim since its wider than the norm!Ypedal wrote:The tire should fit the rim, but the brakes might need work, if the legs of the brakes make contact with the tire before the pads hit the rim, shim it up with washers.
