Battery Increase Jump 70% to 100%

My Battery charge increased from 70% to 100% in the space of 10 minutes.
Should I be concerned?

WillG321 if it’s a one off, then no. The system has to estimate the % full based on voltage levels and sometimes it gets that wrong. Temperature changes can also affect the readings.

GivEnergy have been trying to improve the accuracy of this process in the battery management system. Version 3012 fixed it quite a bit, and 3013 was supposed to be even better but a number people have reported issues with 3013 so that upgrade has been pulled.
If you are on 3013 and it keeps happening you can ask GivEnergy support to downgrade you to 3012
