Why Battery Choice Matters
Your van's electrical system is the heart of your mobile lifestyle. The UK's damp climate and variable weather make battery choice critical.
Battery Types Compared
- Lithium Iron Phosphate (LiFePO4) - 3x lifespan, 80% depth of discharge, 2x weight savings. UK price: £800-£2,000
- AGM (Absorbed Glass Mat) - Lower upfront cost (£200-£400), maintenance-free, but 50% depth of discharge limit
- Lead Acid - Cheapest option (£100-£200), heavy, requires ventilation, short lifespan
UK-Specific Power Calculations
Average UK van lifer needs: 200-400Ah daily. Factor in: LED lighting (30Wh/day), water pump (50Wh), phone charging (100Wh), laptop (400Wh), fridge (800Wh).
UK Buying Guide
Recommended UK suppliers: B&Q (limited selection), Amazon UK (wide range), specialist van converters (expert advice). Look for UKCA marking and IP65 rating for marine use.
