Compatible Dogtra Transmitter Battery

This 7.4V 500mAh Li-Polymer cell replaces the original power pack in Dogtra 1900S, 1902S, 2300NCP, 2302NCP, 3500-NCP, 3502-NCP and ARC 800 series transmitters. It matches the BP74T2 form factor and delivers 3.70Wh capacity for extended training sessions. The green housing identifies the Cameron Sino DS-CS-SDT74SL unit.

Upgrade From Worn Original Cells

Swap this battery when your transmitter runtime drops below a full day of field use or the pack no longer holds a charge after storage. The Li-Polymer chemistry restores the factory voltage curve without requiring a new handset. The jump is worth it if the current cell is swollen, overheats during charging or shows erratic percentage readings.

Check Connector And Dimensions First

Verify the existing pack measures 48.00 x 22.50 x 12.00 mm and uses the same two-pin JST-style lead before ordering. Confirm your transmitter model appears in the supported list such as 1900S, 2302NCP Advance or ARC 802 Camo. This unit fits only the listed Dogtra and Aetertek transmitters; it will not work with collars or receivers.

Questions about this item

What are the exact dimensions of this 7.4V 500mAh Li-Polymer battery so I can confirm it fits my Dogtra 1900S transmitter?

The battery measures 48.00 x 22.50 x 12.00 mm, matching the original BP74T2 form factor for compatible Dogtra and Aetertek transmitter battery compartments.

How do I install this green Li-Polymer pack into my ARC 800 transmitter, and what is the common mistake to avoid?

Open the transmitter battery cover, disconnect the old pack, and connect this unit using the existing lead and connector; the common error is forcing the connector in reversed, which can damage the pins.

When will this 3.70Wh training aid battery need replacement, and what indicates it is time?

Expect 300–500 charge cycles; replace when runtime drops noticeably, the pack no longer holds a full charge, or the transmitter signals low power immediately after charging.
