BigBattery 36V EAGLE2 1.63 kWh LiFePO4 Battery with Heater and Comms

Modernise your 36 V platform with a drop-in lithium battery kit that’s designed to deliver longer life, higher power and improved reliability in a compact GC2/T-105 form-factor tray. Ideal for golf carts, NEVs, industrial equipment, and other 36 V applications.

Why This Battery Stands Out

• Direct upgrade for legacy 36 V systems – This unit fits in most existing tray-mount setups (GC2/T-105 style) and replaces lead-acid packs without major controller changes.

• High-quality LiFePO₄ chemistry – The use of Tier-1 LiFePO₄ cells delivers longer cycle life, improved thermal stability and increased safety compared to traditional lead-acid or generic lithium packs.

• Heater and communications built-in – Integrated self-heating ensures optimal performance in cold conditions, while the CANbus communications interface enables smarter monitoring and system integration.

• Robust performance specs:

  • System voltage: 36 V (nominal 38.4 V)

  • Capacity: 1.63 kWh (40 Ah) nominal

  • Max continuous discharge: 80 A (~3,072 W)

  • Peak discharge: 200 A for 3 seconds

  • Operating temperature range down to –20 °C (–4 °F) and up to 60 °C (140 °F)

• Durable build & protection – Weighs approx. 17.2 kg (38 lb), with IP67 / NEMA-6 protection rating to safeguard against dust and immersion.

• Expandable & future-proof – Supports up to ten (10) parallel connections for higher capacity systems.

• Solid warranty & longevity – Backed by a 12-year warranty, designed to live in service for over a decade.

Key Benefits for Your Application

• Improved range & efficiency – Replacing older lead-acid packs with this lightweight lithium solution boosts usable energy and reduces weight.

• Faster charging & less maintenance – LiFePO₄ requires less upkeep, has better charge acceptance and holds voltage more steadily under load.

• Cold weather ready – The built-in heater supports optimal performance in lower ambient temperatures, helping avoid reduced power or early cut-offs.

• System intelligence – CANbus comms allow the battery to integrate with controllers, display systems or fleet-management tools.

• Upgradable platform – Start with one unit and scale by paralleling more to build higher capacity banks without changing footprint.

Intended Applications

• Golf carts and neighborhood electric vehicles (NEVs) originally using 36 V lead-acid packs.

• Industrial equipment & forklifts where 36 V battery replacements are common.

• Marine or RV house-power systems sized at 36 V.

• Light electric vehicles or custom e-mobility platforms seeking a robust lithium upgrade.

If you’re looking to upgrade a 36 V system with a reliable, long-life lithium battery that’s easy to install and built for real-world use, the BigBattery 36 V EAGLE2 LiFePO₄ kit offers a compelling mix of performance, durability and value. With high discharge capability, cold-weather readiness, communications support and a trusted warranty, it’s engineered for next-level reliability.
