I'm assuming these are the 5000 lipopack, and not A123s, NiMH or NiCds:

No - not necessarily.

I strongly suggest you follow the mfgrs recommended charge rate (typically 1C; 5000 mA for a 5000mAh pack). Some will tell you to go ahead and charge at 2C or 3C, but as you will operate (well) outside the spec - be prepared to pay the price...

I should note that I haven't checked the C-rating on the Venom packs.

Most likely NO!

Some of todays lipos can be discharged up to 30C and above. They do NOT stand such a high charge current. 1C is the generally accepted max charge current - a few exceptions do exist though.

If you only draw 1C at discharge, then the answer is yes. Otherwise NO.

I'm not aware that even A123/K2s can stand similar charge amp to discharge amps. But can't remember seeing any reports of them don't handling it either...
