Default Eco Battery charger issue

New 48 volt 105 Eco Battery. Weird issue. As the battery gets to 100% charge, the charger will sit at 99% charged and the charger will cycle on and off every few seconds. If is disconnect the EB voltage reducer, it stops. When I install a different voltage reducer (with the load side disconnected) it will do the same thing. 2 different batteries have done this. 2 different voltage reducers do this so I’m focused on an issue with the charger.

Any ideas? I’m stumped.

Thanks

You're right, that's a problem which definitely focusses on the voltage reducer hookup.

I ran the 48v + and - power to the voltage reducer through a 2 pole switch. Because of this, I always have the voltage reducer disconnected when I charge it. I had to do it this way because the switch also powers my 48v strobe light.

Not necessarily a fault, just a voltage threshold/deadband issue.

Battery fully charges, charger turns off, converter caused the voltage to drop slightly, charger turns back on...REPEAT

What voltage are you charging to? Dropping the voltage should stop or at least slow this problem.

I believe full charge is 54 volts. The app for the BMS hasn’t been released yet so I’m blind as to what the battery is doing. Keep in mind, this is all happening while the battery is off. This also happens when is disconnect the load from the reducer SR so I can’t imagine there would be a voltage drop.

I have my voltage reducer wired to the key, so with key off, I don’t see this behavior. I did see it with key left on.

I’m thinking this is what I need to do.

There should be a 5th lead on the 48v input side that goes to the key switch. I did run mine all the way to the key. The only annoying part is the wire run and dealing with that janky top screw on my dash instrument panel. I have a 2014 Precedent.
