Overview:
When your power system must deliver through Canadian winters, the Bear Volts 12V 200Ah LiFePO₄ Heated Deep Cycle Battery (Polar Series) answers the call. This battery combines high capacity, premium LiFePO₄ cells, and an integrated heating system to ensure reliable operation even in freezing temperatures. Ideal for RVs, off-grid cabins, trailers, backup systems and marine use where the elements don’t wait.

Key Features:

• 12.8 V nominal (LiFePO₄ chemistry) with a full 200 Ah usable capacity.

• Self-heating function for charging in below-0 °C conditions—mount where you need it, exposed to the elements.

• Robust BMS (Battery Management System) handling up to 200 A continuous charge/discharge; peak discharge 350 A for short bursts.

• High versatility: Up to four units can be wired in series for 24/36/48 V systems, or up to four in parallel for up to 800 Ah capacity. 

• Built with grade-A, UL-listed cells and housed in a fully enclosed ABS casing that’s dust & waterproof to IP65.

• Bluetooth monitoring app (iOS/Android) for status tracking via the BMS. 

• Dimensions: approx. 19.2″ × 6.7″ × 9.5″, Weight: ~18.9 kg (41.7 lbs) — compact for its class.

• 6-year Canadian limited warranty (full replacement for first 3 years, pro-rated thereafter).

Why Choose a Heated LiFePO₄ Battery?
Cold temperatures pose a serious threat to battery performance—traditional lead-acid or standard lithium batteries can struggle to charge when the ambient drops below freezing. The Polar series counters this with built-in heating so you maintain full charging capability, maximum output and long life, even in harsh winter conditions.
In short: you get full performance year-round, fewer worries and greater system reliability.

Applications:

• Medium to large RVs and trailers (tongue-mounted or under-step installations)

• Off-grid cabins and remote power systems

• Winter camping setups, snowmobile trailers, ice-fishing huts

• Marine house-battery systems exposed to cold climates

• Backup power installations where temperature control may be limited

Technical Specifications Snapshot:

• Nominal Voltage: 12.8 V

• Capacity: 200 Ah (≈ 2,560 Wh)

• Continuous Charge/Discharge: 200 A

• Peak Discharge (5-10 seconds): 350 A

• Parallel/Series Capability: Up to 4 in series or parallel (e.g., 48 V or 800 Ah banks) 

• Enclosure: IP65 ABS

• Terminals: M8 posts (bolts included)

• Warranty: 6 years (Canada)

• Weight: ~18.9 kg / 41.7 lbs

Installation & Usage Tips:

• Ensure your charger or converter is lithium-compatible (or switch to one) for optimal performance—polar series batteries prefer li-ion charge profiles. (See Q&A on site) 

• For series/parallel configurations, use matching units and proper wiring practices to maintain balance and lifespan.

• Mounting location: thanks to the self-heating function, this unit can be installed in places subject to cold (e.g., trailer tongue) but ensure the case is not enclosed without ventilation to avoid heat buildup.

• Monitor via Bluetooth app to track cell voltages, temperature, charge status—helps ensure you stay ahead of maintenance.

• To maximize battery life: avoid deep-discharges below ~20%, and keep the battery above freezing when possible—though thanks to the heating system you have more flexibility than standard batteries.
