Hi team,
Looks to me that an increasingly large proportion of ebike motor manufacturers are getting into the closed system business (including Bafang, shame on them). This means that all of us who have bought expensive Cycle-satiator chargers, are kind of unable to use it on most of our non-DIY batteries since the Satiator just "pushes" power and, if the battery system does not recognize a specific signal (which the Satiator won't provide), it simply won't charge the battery at all.
Looking at the Stromer battery though (https://www.stromerforum.ch/showthread.php?tid=2572&page=2) and what is behind the connecting port, looks to me that most closed-system batteries are standard batteries with a standard BMS, EXCEPT that, between the charging plug and the in/out of the BMS, they have put in place some sort of system that controls the flow of electricity between the BMS and the connecting plug. A kind of "gate keeper".
HOWEVER, If I am correct, would it technically be possible to kind of bypass this controlling system by simply welding 2 charging wires to the + and the - of the BMS directly, and creating an XLR connecting port so that we can connect the Satiator directly? This way we could charge using the Satiator by bypassing this "gate keeper", and from time to time, if needed, charger the battery using the standard Charger.
Obviously that would void the battery warranty, but between voiding a warranty and having a battery degrading 3-5 faster than normal just because it gets charged at 54.6V (for a 48V battery) rather than a softer 52V, my choise is clear.
What do you think?
