You have 12V, not plus 12V and minus 12V which is 24V. What you label as -12V is actually 0V.

An ordinary older type of Lithium Ion cell is 4.20V when fully charged so your charger should have an output up to 12.6V, not 12.0V.

The charger circuit should have wires connected between the series batteries so that it makes it a balanced charger.
