Product Overview:
When you need reliable battery power in cold climates or compact systems, the Bear Volts 12 V 100 Ah LiFePO₄ Heated Deep-Cycle Battery (Polar Series) delivers. Featuring LiFePO₄ chemistry, a built-in self-heating function, and high-current capability, this battery is perfect for RVs, lightweight trailers, ice-fishing huts, off-grid cabins or marine house banks exposed to harsh conditions.

Key Features:

• Nominal voltage: 12.8 V; Capacity: 100 Ah (~1,280 Wh) 

• Built-in self-heating function enables charging in sub-zero conditions — ideal when battery is exposed to cold ambient temps. 

• Maximum continuous charge/discharge current: 100 A. Peak discharge current: 260 A for 5-10 seconds. 

• Series/parallel capability: Up to four units in series (24V/36V/48V systems), or up to four units in parallel (up to ~400 Ah) for higher capacity banks. 

• Built-with Grade A UL-listed cells; integrated BMS featuring high/low voltage cut-off, temperature protection, cell balancing, over-current and short-circuit protection. 

• Rugged build: Fully enclosed ABS casing, dust & waterproof to IP65, M8 terminal posts (bolts supplied). Weight approx 9.6 kg (21.2 lbs). Dimensions approx 10.3″ × 6.7″ × 8.3″. 

• 6-year limited Canadian warranty: full replacement first 3 years, then pro-rated years 4–6. 

Why Choose a Heated LiFePO₄ Battery?
Standard batteries struggle in cold environments: charging slows or stops, capacity drops, lifespan is impacted. With this Polar Series battery you get built-in self-heating, enabling charging even when ambient is below 0 °C — so your power system remains reliable year-round, even in harsh weather. 
Lithium iron phosphate (LiFePO₄) chemistry also offers long cycle life, lighter weight, higher usable capacity and better performance compared to traditional lead-acid.

Applications:

• Lightweight RVs, tent trailers & over-land vehicles

• Off-grid cabins, winter retreats & ice-fishing shacks

• Boats and marine setups in cold or seasonal climates

• Winter camping gear, mobile power setups, backup power systems in cold regions

Technical Specifications Snapshot:

• Nominal Voltage: 12.8 V 

• Capacity: 100 Ah (~1,280 Wh)

• Continuous current (charge/discharge): 100 A

• Peak discharge current (~5-10 s): ~260 A

• Series/Parallel wiring: Up to 4 in series (24V/36V/48V) or up to 4 in parallel (~400Ah)

• Weight: approx 9.6 kg / 21.2 lbs

• Dimensions (approx): 10.3″ × 6.7″ × 8.3″

• Warranty: 6-year limited in Canada

Installation & Usage Tips:

• Ensure your charger or power conversion system is compatible with LiFePO₄ chemistry (CC-CV profile) to maximise performance and lifespan.

• When wiring multiple batteries in series or parallel: use matching units (same age/capacity), consistent wiring lengths, proper fusing and avoid mixing battery types.

• Even with built-in heating you still want to avoid extreme ambient exposure when possible; good ventilation and proper mounting will help maintain performance and longevity.

• Monitor battery status (voltage, temperature, charge/discharge etc) — many units offer Bluetooth monitoring. This helps you stay ahead of maintenance and usage issues.

• To maximise lifespan: avoid very deep discharges (e.g., down below ~20-30% state of charge), keep ambient and operational conditions moderate, and store at partial charge if unused for long periods.
