Here is my e-mail conversation with the TechRep at K2.


I want to wire two 12v10aH K2 batteries in a parallel circuit to yield a 12v20aH pack. Is this acceptable? Will a single K2 charger charge both batteries simultaneously?

Great product!

Thanks, Mark



Yes, you can wire them in parallel and still use our charger to charge them up. Note, if you are dealing with high amperage, the parallel wiring doesn't mean double the max amperage.
