Direct replacement for Dogtra 1900S

This Cameron Sino lithium-polymer battery matches the original BP74RS specifications with a 300mAh capacity and 7.4V output. It fits the 1900S and 1902S receiver collars exactly, using a fully decoded chip that communicates with the device like the factory cell. The pack measures 32.22 x 27.00 x 12.06mm and weighs 17.8g.

Upgrades an ageing or swollen original pack

When the stock cell no longer holds a full day's charge or shows physical swelling, this unit restores the intended runtime without modifying the collar. The jump is worth it once the original battery drops below usable capacity or fails to complete a training session. No soldering or adapter is required; the connector aligns with the existing socket.

Steady output across a full training day

The lithium-polymer chemistry delivers consistent voltage from start to finish rather than tapering off early. Protection circuits guard against overcharge, over-discharge, over-voltage and short circuits during extended use. After two or three full charge cycles the cell reaches its stable performance plateau for reliable operation in the field.

Questions about this item

What are the exact dimensions of the 32.22 x 27.00 x 12.06 mm pack so I can confirm it fits my Dogtra 1900S receiver?

The lithium-polymer pack measures 32.22 mm long, 27.00 mm wide and 12.06 mm thick, matching the original BP74RS footprint for the 1900S and 1902S receivers.

The supplier notes the connector must be properly connected — what is the common mistake during installation?

The fully decoded chip requires the plug to seat fully; a partially inserted connector leaves the receiver dead even though the battery is charged.

After how many charge cycles does the 300 mAh cell reach its best performance?

The manufacturer states a new cell achieves optimal capacity after 2 or 3 complete charge and discharge cycles.
