01
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
2000–3500 cycle lifespan vs 500–1000 for lead-acid alternatives

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
🧠
03
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 at 2000+ cycles

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

BMS Deep Dive
Protection on every front.
The Putac BMS provides six layers of active protection in every pack.
🔋
Overcharge Protection
Cuts charging current when any cell reaches maximum voltage. Prevents cell swelling and electrolyte breakdown.
📉
Over-Discharge Protection
Disconnects load when any cell drops below safe minimum voltage, protecting cells from irreversible capacity loss.
🌡️
Thermal Management
Monitors temperature across the pack and throttles charge/discharge rates to keep cells within safe operating range.
⚡
Overcurrent Protection
Detects and disconnects within milliseconds if current exceeds safe limits — protects cells and external circuits.
🔌
Short Circuit Protection
Hardware-level fast-blow protection triggers in microseconds on a dead short — protecting the battery and vehicle wiring.
⚖️
Cell Balancing
Passive balancing keeps all cells at matched voltage, preventing capacity loss and extending pack lifespan over hundreds of cycles.
