Lipos in general honestly dont care how fast you charge them though charging/discharging them hard will reduce the longevity of the battery (not significaly from my experiance) the issue comes with the internal resistance of the pack and the thickness of the wires causeing the pack (or the wires) to get hot. Keep an eye on the battery the first time you charge it and slow the rate if it or the wires get noticeably warmer than when you normally charge them. If they dont get any warmer you're good
