faster than most systems, but this can
still take up to a few hours to reach
100%. You may see the SoC remain at
~99% until balancing finishes.
You can still use the Flex system
without charging up those last few
percentage points, but you won’t get
the max capacity until the system
reaches 100%. Just give your unit a full
overnight charge every now and then to
ensure the maximum charge capacity is
reached.
Charging for Long-Term Storage

Cell Balancing
Lithium battery packs with multiple cells
can become unbalanced after heavy
use, or going a long time between full
charges. This means that one cell group
is at a higher or lower state of charge
(SoC) than the others.
In order to resolve this imbalance, the
battery needs to be charged while
the intelligent management system
automatically balances each cell group.
The Flex Battery employs a rapid cell
balancing system which is over 10x
General Information
When charging your Flex system,
the power console LCD screen will
indicate an estimated charge time
and the amount of power being sent
to the battery. This estimated charge
time is based on the power input and
output numbers at that moment, and it
will change as the average charge or
discharge rates fluctuate. The power
console LCD combines the states of
charge of all batteries in your Flex
system as a percentage of the total
combined capacity.
When more than one battery is
successfully connected, any charge
input will charge all batteries, even the
Standard Wall Charger input (so long
ATTENTION:
Do not allow your Flex system to remain in storage at a low state of charge for a long time. This may damage
your Flex Battery and void your warranty.
