  BMS security system - Battery Management System

  Comprehensive battery protection:

  ✓ Temperature Protection

  • Cell temperature monitoring
  • Automatic shutdown on overheating
  • Cooling before reuse

  ✓ Short Circuit Protection Protection)

  • Immediate cut-off in case of short circuit
  • Damage protection
  • User safety

  ✓ Over-charge protection

  • Automatic charging stops at 100%
  • Extends battery life
  • Prevents cell degradation

  ✓ Over-discharge Protection

  • Shuts down before complete discharge
  • Protects cells lithium batteries from damage
  • Retains capacity for years

  Why is BMS crucial?

  Lithium-ion batteries are efficient, but require intelligent management. BMS system in the Indel B power bank:

  • Extends lifespan to 500+ cycles
  • Ensures safe use
  • Optimizes charge and discharge efficiency
  • Protects against common lithium battery problems

  500+ cycle lifespan - long-term investment

  What does 500 cycles mean?

  1 cycle = full charge and discharge of the battery

  500 cycles means:

  • 500 full battery charges
  • Or 1000 half charges (discharge to 50%)
  • Or 2500 cycles 20% (discharge to 80%)

  Practical lifespan calculation:

  Scenario 1: Heavy weekend use

  • 52 weekends per year
  • 1 cycle per weekend
  • 500 cycles = 9.6 years of use

  Scenario 2: Summer use

  • 4 months of summer (16 weekends)
  • 2 times per weekend
  • 500 cycles = 15.6 years of use

  Scenario 3: Occasional usage

  • 20 times a year
  • 500 cycles = 25 years of use

  What happens after 500 cycles?

  The battery DOES NOT stop working! Capacity gradually decreases:

  • After 500 cycles: ~80% of original capacity (200Wh)
  • After 1000 cycles: ~60-70% of capacity (150-175Wh)
  • Still usable for years to come

  Charging the power bank

  How to charge a 250Wh battery?

  Power sources:

  ✓ From the car battery (12V)

  • While driving, the engine charges the car battery.
  • The power bank charges from the 12V installation.
  • Charging time: ~3.8 hours
  • The perfect way on the road

  ✓ From a camper/van installation (12V/24V)

  • When connected to external power
  • Charging from solar panels
  • Automatic 12V or 24V recognition

  ✓ From a charger 230V AC → 12V DC

  • At home from a socket (requires charger - sold separately)
  • Charging before you go
  • Always-ready power bank

  ✓ From solar panels (12V-30V)

  • Eco-friendly charging in the field
  • 100W+ panel required for optimal speed
  • Ideal for long expeditions

  Charging time ~3.8 hours:

  250Wh / 100W (charging power) = 2.5 hours theoretically

  Practically 3.8 hours due to to:

  • Charging efficiency (~80-85%)
  • BMS security
  • Loading slows down at 80-100%

  This means:

  • During a 4-hour ride → fully charged
  • Overnight stop with charger → ready in the morning
  • 100W solar panel on a sunny day → fully charged

  Operating temperature -10°C to +40°C

  Wide range for every season:

  ✓ Winter (up to -10°C):

  • Power bank works in frost
  • Protected against frost
  • Perfect for winter trips

  ✓ Summer (up to +40°C):

  • Overheating protection
  • Stable operation in heat
  • BMS monitors temperature

  Operating tips:

  In winter:

  • Keep the power bank close to your body before use (e.g. in a backpack)
  • Capacity may be slightly lower in frosty conditions
  • Recovers full capacity when brought into a warm environment

  In heat:

  • Avoid direct sunlight
  • Keep in the shade or a cool place
  • BMS automatically protects against overheating

  Dimensions and weight - compactness

  228 x 152 x 48 mm, 1.7 kg:

  ✓ Flat profile 48 mm - easy to store
  ✓ Weight 1.7 kg - lighter than a laptop
  ✓ Compact - fits anywhere
  ✓ Easy transport - in a backpack, bag

  For comparisons:

  • Laptop 15": ~2-2.5 kg
