hmmm, I wouldnt use existing/old style chargers on LifePo or A123. You really should use a balance charger which monitors the voltage of each cell during charge. This will help avoid ruining your nice new battery. I presume the K2 has a balance plug?

the electronics for charge regulation and balancing are built into the
battery case of the SLA replacement sets. So, just two terminals.
That's all
