Charging a 150mAh pack at 300mA is 2C charge rate - you can get away with that as long as you are careful and only charge for 20 min or so.
Charging a 70mAh pack at 300mA is 4C charge rate. There is no need to "try one and see". Even if you take the pack off the charger in 7 or 8 min, the batteries will definitely be fried in only 1 or 2 charge cycles because they are not designed for a fast-charge.
