I got a 48V 20Ah LiFePO4 battery from a chinese company on Ebay, and it came with a Vpower 5-amp 48V charger for LiFePO4. Does anyone have a manual or instruction sheet for this charger?
I think the battery had a fairly full charge when it arrrived, it drove my ebike at fairly good speed with no apparent sagging. I put the battery on the charger, and the two LEDs came on. One was red and stayed that way throughout the charging session (which wasn't very long). The other was yellow when it came on, stayed that way for about 10 minutes, then turned green. A few minutes later it turned yellow again, then green, changing color every minute or two. I disconnected everything after 30 minutes or so, not wantinng to overcharge the battery before I knew what the charger was trying to tell me. The first LED stayed red for the entire 30 minutes, and I don't think the battery ever reached a full charge. Maybe that first LED would have eventually turned green if I let the battery charge all the way up, but I don't know - I'm only guessing about that part.
Does anyone know what these LEDs mean?
