FES BATTERY PACK GEN2 Version 1.18
8. When first cell reaches 4.160V, charging current is reduced. If there is a big
difference between cells (more than 50mV) then it can take quite long until they all
reach 4,16V, as charging current is only 1A.
9. When finally, all cells reach 4.160V (+/- 2mV), then BMS send a signal to
CHARGER to stop charging. At this point
become
continiously
This is clear message that charging cycle is properly completed!
10. Switch OFF BMS on top of Battery pack. Unplug charger from outlet. Unplug
charging cables and signal cable from Battery pack.
11. Charge second Battery pack!
Both battery packs must have approximately the same cell voltage levels
(close to 4.16 V per cell), before usage. Using two packs with too much
difference in voltage levels is not allowed!
Maximum 0,4V difference between total voltages of both packs is acceptable.
If is more is not acceptable!
For instance, Pack 1: 58,24V (4.160 per cell), Pack 2: 57,82V (4,130V per
cell), this is just acceptable!
If thunderstorm is approaching, stop charging immediately and disconnect
the charger from the wall.
