Product Description
The Trontek TK-LiFe-5145 is a 51V 45Ah (2.29 kWh) lithium iron phosphate traction battery built for electric 2-wheelers. LFP chemistry gives the safest lithium option on the road — no thermal runaway, no fire on puncture or short — with 2000+ cycle life and steady output voltage across the full discharge. The pack is optimised by its battery management system (BMS), which monitors every cell to protect against over-charge, over-discharge, over-current and short circuit, and balances cells independently for safe and accurate operation. Trontek is an established Indian battery manufacturer with 1 GWh production capacity and in-house R&D and testing.
Frequently asked Questions8
- Q: Which electric 2-wheelers is this battery compatible with?
- A: Any 48VV-system electric scooter or motorcycle whose controller accepts a 51V nominal LFP pack with a 57.6V charge voltage and 44.8V cut-off. Confirm connector type (Top-mounted connector with buzzer and breather) and charger rating with iTarang before purchase; controller and charger must match.
- Q: What range will I get?
- A: The pack stores 2.29 kWh. A typical e-scooter consumes 25–35 Wh/km, so expect roughly 66–92 km per full charge depending on rider weight, speed, terrain and motor rating.
- Q: How long does it take to charge?
- A: At the standard charge current (0.3C (≈13.5 A)) a full charge from cut-off takes about 3.5–4 hours. Use only a Trontek-approved LFP charger with a 57.6V CC-CV profile; a lead-acid charger will damage the pack.
- Q: Is LFP safer than the NMC batteries in the news for fires?
- A: Yes. LFP has a far higher thermal-runaway threshold and does not release oxygen when abused. This pack has been tested for over-charge, short circuit, nail puncture and thermal shock with no fire and no explosion, and the BMS cuts load on over-current, over-discharge and short circuit.
- Q: How many years will the battery last?
- A: Rated for 2000 cycles at 0.5C and 25°C. At one full charge per day that is roughly 5–6 years of daily use before capacity drops to end-of-life, versus about 1–1.5 years for lead-acid EV batteries.
- Q: Can I use it in hot Indian summers and in the rain?
- A: Discharge is rated −20°C to 60°C; the BMS throttles or cuts charging outside safe limits. Extruded aluminium enclosure with handle, buzzer and breather valve — mount inside the vehicle's battery compartment and keep the connector dry. Store between 15°C and 35°C.
- Q: Does it need maintenance?
- A: No. No water topping, no acid, no terminal corrosion. Keep the connector clean and avoid leaving the pack at 0% for long periods.
- Q: What happens at end of life?
- A: The pack is fully recyclable. Return it through iTarang's battery buyback / take-back programme under the Battery Waste Management Rules, 2022. Never dispose of it in household waste.
