Default 12 volt deep cycle battery question

Setting up a charger station for lipos. Searched through the forums and didn't find a solid answer, so here goes.
I have a 105AH deep cycle marine/RV battery as a source. I want to run 2 Astro Flight 109s at the same time to charge 2s2p 4200mah packs. Will be stepping up to larger packs later on.
Will this practice harm the source battery or cause problems for the chargers?
Thanks for any input.

The chargers are designed to run on the voltage provided by a 12V lead-acid battery, and they will shut down when the source voltage gets too low. You aren't going to hurt them by connecting them to the very power supply they were designed to use.

1C on a 105Ah battery is 105 Amps. You won't be anywhere near a 1C draw. That battery will just laugh at the load you put on it.

Matt,
Thanks for the reply. That's what I thought, but being new to the high power electrics, I just wanted to make sure.
