We have 2 sets of TP5300 and started out with one TP1010 charger. We found that to speed up the charging process an additional charger would help more than an additional set of batteries, and costs much less than additional set of batteries. We now have two sets of batteries and two chargers. Charge time is 45 minutes per set of batteries.

Go to the field with 2 charged batteries, fly, put on charger, fly second pack, put it on second charger, first pack will be through in about 20 additional minutes. We did find it necessary to buy a generator to power the chargers at fields without electric available. The heavy liesure batteries will not sustain the load and the charger will quit due to low input voltage.
