Recharge time on this bike is about 2 1/2 hrs, from what I call "dead dead" . That means that if I draw the battery all the way down to it's lowest voltage allowed, and still yet be able to run at all but at limited speed and power. Think of a throttle rollback, or a rev- limiter....
This bike has two " computers" in it that regulate the voltage and the like. The first ( Cycle - Analyst) one has user variable amp- draw, voltage limits at the low end, power ramps, etc. Essentially one can tune it to ride like a docile cruiser, or a rocket ship.
The second " computer" is a Battery Management System. The BMS monitors each one of the 24 series wired cells, and serves to balance the pack during charging and dischaging, balance the cells at steady- state, as well as shutting the pack down if a low voltage event occurs. Too low a voltage serves as a death knell to these cells, as well as too high a voltage come to think of it. It also has a high temperature sensor limit built into it.
This second system, the BMS, is what got hurt.... I had the battery on the bench, soldering up some better quality connections ( Super-Deans, gold plated stuff from the R/C world) on the "charging " side of the battery. I was just making an adjustment, and l carelessly let the soldering iron tip stray onto the other lead at the new connection.... "Poof" went that soldering iron tip, and all I could see for a minute were green spots.... I guess my thoughts that one can weld with a pack of this power are indeed very true.
There is no real visible damage to the BMS, or any other component, but the symptoms it is now showing (while re-connected ) all point to BMS damage.It will not allow the charger to kick in, and without some serious prodding the CA and controller will not come to life.
While awaiting some responses from the guys here at Stealth USA who I hope will help me source a new BMS, I am working on some driveline improvements on the bike.
