Fireproof LFP Chemistry
Lithium Iron Phosphate (LFP) is not just another battery chemistry — it's the safest one available for consumer EVs. Unlike NMC or NCA batteries, LFP cells have an intrinsically stable chemical structure that resists thermal runaway even under extreme abuse.
- Thermal runaway threshold above 270°C vs 150–200°C for NMC
- No oxygen release during thermal events — dramatically lowers fire risk
- Stable performance across India's full temperature range: -20°C to 60°C
- 6000+ cycle life for long-lasting daily EV use
Intelligent BMS
Our proprietary Battery Management System is the brain of every Putac pack. It monitors every cell in real time and makes hundreds of decisions per second to maximise performance, protect cell health, and prevent failures before they happen.
- Per-cell voltage monitoring — detects imbalances instantly
- Temperature sensing across the full pack
- Overcharge, over-discharge, overcurrent, and short-circuit protection
- State-of-Charge (SoC) accuracy within ±2% for reliable range estimates
- Adaptive charging current management for fast charging without cell degradation
Fast Charging
Fast charging in EVs is not just about pushing more current — it requires precision management to protect cell chemistry. Our BMS enables true fast charging by dynamically adjusting current based on cell temperature, SoC, and health history.
- 20% to 80% in 45–90 minutes with a compatible charger
- Smart taper charging in the final 20% protects top-of-charge cell stress
- Thermal monitoring prevents heat-induced degradation during fast charge
- Cycle life maintained even with daily fast charging — tested for long cycle life
IP65 Protection
Indian roads are not kind to electronics. Monsoon rain, dust from unpaved roads, vibration from potholes, and temperature swings all degrade cheaper batteries quickly. Every Putac pack is built to survive India as it actually is.
- IP65 rating: complete dust-tight seal + protection against water jets
- Reinforced ABS + aluminium enclosure withstands mechanical impacts
- Vibration-damped cell mounting — tested on Indian road profiles
- Corrosion-resistant connectors and terminals
- High-temperature resistant cabling throughout
