Battery Bank Installation: In Telecom BTS site 48 volt DC battery bank installed. there are 24 cells in each Battery Bank each is having the 2 volt DC. These battery bank are installed on stand and grouted in the shelter properly. These battery bank have certain distance from the SMPS and we should try to keep O/P of each terminal is in opposite direction of SMPS. Grounding of Battery bank is done with the IGB by the 35 mm square grounding cable & connected to EGB (Internal Grounding Bar).
how many volts does a bts uses for it to operate depending on size
By BTS, do you mean Base Transceiver Station? Such equipment can be found in cell phone towers. Usually a BTS runs on 48V DC.

Typically one GSM BTS hardware can cover a few numbers. Also, some numbers can also be covered by more than one GSM BTS. Since one cell is covered by exactly one BTS, the cell id uniquely identified the concrete BTS.
3g BTS is greater than 2g bts. and it is with new technologies.
Indoor BTS: It is placed in a shelter Air-condition is must Very sensitive Outdoor BTS: No shelter required Air-condition is not a must Not very sensitive comparing to indoor bts
-48 v is given to BTS because in this voltage Noise generation is minimum. Because two terminal comes out from the battery and through red color wire we ground the +ive terminal so that possibility of noise interference will get zero because noise occurs only in the +ive terminal that's why we use -ive voltage in the BTS.
GSM900 transmitted power from BTS: 39dBm GSM1800 transmitted power from BTS: 36dBm
typically 2km

Hi dear one BTs can handle maximum about 2000 user at a same time best regard Salman khan safi
This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation So the main function of this is 1) To convert AC to DC 2) To control overloading
