Hi guys, I have had my MP III and a SM3 for almost two years now, both working flawlessly. Recently, my MP III with a 48V 10Ah battery started delivering jittery power with sudden losses of power. When accelerating, the battery indicators go from full to a dim one LED, then to full again. During cruising it may drop to two LED, then jump to three and one again , etc. And it's not only the indicator, I can feel it in the motor delivery as well... Anyway, I've investigated the following until now:
1. Couldn't make a connection between bumps and loss of power. All main connections seam to be ok.
2. Take apart 48V battery. 57.5V measured at full charge. Each cell was 3.6V, so it's not an unballanced or dead cells.
3. Switched the 48V battery for a 36V 15Ah => no more power loss. This would lead me to believe it's either a throttle problem (I used a 36V throttle as well) ot a battery
BMS problem, but one that would not affect charging.
Does anyone have any ideas about what and how could I test?
Cheers.
