Why the generation matters
Expion360 introduced a high-density 12.8 V Group 27 132 Ah LiFePO4 battery with SmartTalk, VHC internal heating and CAN Bus communication in its 2024 generation. Scout adopted that battery family for model-year 2025 campers.
In February 2026 Expion360 announced a new Group 27 battery rated at 140 Ah, describing it as an increase from the then-current 132 Ah generation. MHS therefore treats 132 Ah and the announced 140 Ah successor as different products rather than quietly merging their specifications.
What 12.8 V and 132 Ah mean
The nominal values describe the battery's electrical class and stored charge. Multiplying 12.8 V by 132 Ah gives about 1.69 kWh of nominal energy.
That 1.69 kWh is an MHS calculation from the published nominal values, not a separate manufacturer energy claim. Real usable energy depends on BMS limits, current, temperature and the surrounding system.
Why Group 27 matters
Group 27 is a common RV and marine battery footprint. Expion360 promoted the 132 Ah version as a high-density option that puts more capacity into a familiar physical class.
A Group 27 label is not a universal guarantee of drop-in fit. Terminal position, hold-down hardware, cable bend radius and service clearance still need to be checked in the actual camper.
VHC internal heating
VHC means Vertical Heat Conduction. Expion360 describes VHC as internal heating intended to prepare LiFePO4 cells for cold-weather charging and operation.
LiFePO4 cells should not accept normal charge when cell temperature is too low. A heated battery can warm itself before allowing charging, but it still follows BMS and charging-source limits.
MHS explanation.“Heated” does not mean unlimited charging at any outside temperature. The internal heater itself consumes energy, and the battery must have a suitable source available to warm the cells.
SmartTalk Bluetooth
This 132 Ah generation is Bluetooth-enabled and is part of the SmartTalk ecosystem. Expion360 describes app-based monitoring of compatible batteries, including battery status information.
Bluetooth is local wireless access. It does not automatically provide internet monitoring from another city. That would require other connected equipment.
CAN Bus communication
Expion360 also lists CAN Bus capability for this generation. CAN allows the BMS to exchange data with compatible system electronics.
A CAN-capable battery does not prove that a specific camper display shows every BMS parameter. The surrounding controller and network must support and correctly configure that communication.
BMS protection
The manufacturer describes protection against high and low voltage, short circuit, overcurrent and unsuitable charging conditions.
These protections are inside the battery. They do not replace external branch fusing, correct conductor size or the camper's main isolation architecture.
Serviceable top
Expion360 highlights a serviceable top for this Group 27 generation, allowing manufacturer-authorized service of items such as the BMS, internal heater and cell packs.
This should not be interpreted as a DIY invitation. Internal battery work remains safety-critical and should follow approved procedures.
One battery or two
Expion360's Scout announcement states that model-year 2025 Scout campers would use one Group 27 132 Ah VHC battery, with an option for a second battery.
Two matched 132 Ah batteries in a correctly designed 12 V parallel bank provide 264 Ah nominal capacity. Quantity is a camper-specific fact: MHS links the component model separately from the number installed.
Why winter energy planning changes
A cold battery compartment can be much colder than the living area. Internal heating is therefore useful in truck campers, but it adds an electrical load exactly when solar production may be low.
Before winter travel, identify whether the battery compartment is heated, which charging sources remain available in cold conditions and how the system behaves when the battery heater is active.
The 2026 successor
On February 5, 2026 Expion360 announced a next-generation 12.8 V / 140 Ah Group 27 battery expected in the second half of 2026. The announcement explicitly compares it with the 132 Ah current generation.
That statement gives a useful boundary. A later Scout documented with 140 Ah must not inherit this 132 Ah card. During the transition, the battery label is more reliable than assumptions based on model year alone.
What to check in a Scout
Confirm the capacity on the physical battery label and note whether one or two units are fitted. Open SmartTalk and verify that the installed batteries are visible. If the camper claims CAN integration, verify that its main monitoring system actually receives battery data.
Inspect hold-downs, cable protection and external fusing. A sophisticated battery still needs a mechanically and electrically sound installation.
Why MHS links this card to Scout models
Scout model evidence identifies Expion360 132 Ah batteries, and Expion360 independently announced the Group 27 132 Ah VHC battery as Scout's model-year 2025 battery platform.
This is stronger than a generic brand mention. Where a Scout page omits some technology wording, the model generation is supported by the OEM program evidence while the exact quantity remains in the camper record.
Key takeaway
Expion360 Group 27 132 Ah SmartTalk & VHC is a distinct 2024–2026 battery generation. Its internal heating, Bluetooth and CAN capabilities should remain separate from the announced 140 Ah successor.
