The BP-5S battery is compatable with the Hemisphere family of receivers including; the Hemisphere S631, Stonex S900A and Carlson BRx7. It is also compatible with the Hemisphere CW400 / P9 data collectors. With the locking channels cut into the battery, you can be assured that your battery is not going to move unexpectedly even if your battery door is not securely locked in place. The smart indicators make it exceptionally easy to check the remaining power in the battery.

Extended Battery Life
When surveying in the field, it is important to have a battery that will last all day. Having to return regularly to your base station to change batteries and reset your base after you run out of power costs you time and money. The Hemisphere S631 has the ability to run up to 12 hours continuously with these internal batteries. Data collectors like the P9 and CW400 can run up to 10 hours off this battery as well. Although nice and compact, with the ability to fit several batteries inside of one pocket, the S631 / BRx7 battery boasts a large 3400 mAh size. This allows for all day use.
The smart indicators make it exceptionally easy to check the charge on the batteries charge. The four levels of charge make it really easy to check on the status of the battery, and with the sliding locks built into the battery it is easy to hot swap the batteries in the field. The BP-5S slots into the receiver and data collector, with locking channels to keep it in place, even if the battery door is not secured. With the locking mechanism of the battery, you can ensure that you never accidentally lose a battery to an unexpected bump while moving in the field.
With the BP-5S you have a battery you can take into the cold or heat and not have to worry about large performance drop offs. They will be able to power your receivers whether it is -30°C or 30°C. Here at Bench-Mark, we have tested these batteries inside our deep freeze, to cruel Canadian winters, to sweltering prairie summers, and they never stopped woking. Base on a Li-Ion cell, you get a robust and well tested battery that you can be confident will power your equipment for years to come.
Specifications
Yes. The BP-5S is designed for the Hemisphere S631 and Carlson BRx7, and it is also compatible with the Hemisphere CW400 and P9 data collectors. The same battery is also listed for the Stonex S900/S900A, making it useful when supporting multiple compatible survey instruments.
The S631 and BRx7 use two BP-5S batteries. The Carlson BRx7 manual lists two BP-5S batteries as part of the receiver kit, while the S631 documentation specifies operation with its dual-battery configuration.
The battery is rated at 3,400 mAh, 7.2 V, and 24.5 Wh per battery. With two batteries installed, the S631 and BRx7 are specified for approximately 10-12 hours of operation, depending on the receiver and operating conditions. The S631’s official specification lists up to 12 hours in rover UHF mode with two batteries.
Yes. The S631 is designed for hot-swappable batteries, allowing one battery to be replaced while the receiver remains powered by the other. This is particularly useful during long field sessions when maintaining an active RTK workflow is more important than stopping to restart the receiver.
The battery has an integrated smart charge indicator with four charge levels, allowing you to check its approximate remaining charge before installing it or during field operations. This makes it easier to rotate charged batteries and avoid unexpectedly running out of power during a survey.
Yes. The BP-5S is compatible with the CW400 and P9, in addition to the S631 and BRx7. The published specifications indicate up to approximately 10 hours of operation from one battery in the CW400/P9, although actual runtime will vary with equipment usage.
The product information specifies operation from approximately -30°C to 30°C and identifies the battery as a rechargeable lithium-ion cell designed for field use. Actual runtime and battery performance can vary with temperature, so extreme conditions should be considered when planning spare batteries for extended field sessions.
