There is no difference between the low limit and the limit holdem in terms of betting limitations because both of them have the rule of permitting a defined highest bet available. Of course in terms of specific amounts they may vary depending on the predefined rules in the poker room/table you are playing in. For more detailed information read
Texas Holdem rules here.
Regarding the upper limit with respect to the lower limit it has to be twice the amount of the lower as in most of the online casinos, but just in case check the particular rules of the place you are playing at before sitting.
The blinds also depend on the stakes stated for the specific table of your choice. Hope it was heplful
