Installation duration can vary slightly depending on base vehicle architecture (EV auxiliary loop vs under-chassis diesel routing). Final fitting time confirmed upon booking.

Vehicle Platform Compatibility

⚡ Electric Vehicle (EV) Campervans

  • Regulated 25A Current Draw: Safely isolates and limits power draw to avoid overloading the vehicle's primary high-voltage to low-voltage DC-DC converter.
  • Intelligent Ignition Activation: Charges only when the vehicle is powered in "Drive" or "Ready" accessory mode.
  • Solar Harvest Priority: Automatically channels rooftop solar energy first to conserve drive battery capacity.
  • Shore Power / Hook-Up Compatible (2018+ Motorhomes): Most motorhomes manufactured from 2018 onwards are fitted with a factory 20A AC-to-DC mains converter — fully sufficient to charge the LiFePO4 battery bank via your existing hook-up connection. No additional charger required.

🚐 Diesel & Petrol Motorhomes

  • Smart Alternator Compatibility: Overcomes Euro 5/6 regenerative braking voltage drops to deliver a rock-solid, multi-stage charge.
  • IP68 Waterproof Sealed: Fully sealed enclosure permits under-chassis, external battery box, or wet locker mounting.
  • Heavy-Duty Quick Connects: Pre-fitted disconnect plugs enable rapid servicing and winter isolation.
  • Shore Power / Hook-Up Compatible (2018+ Motorhomes): Most motorhomes manufactured from 2018 onwards are fitted with a factory 20A AC-to-DC mains converter — fully sufficient to charge the LiFePO4 battery bank via your existing hook-up connection. No additional charger required.

❓ Frequently Asked Questions

Is a 320Ah or 640Ah heated lithium battery suitable for off-grid campervan use in winter? Yes. The built-in thermal heating pads activate automatically below 0°C, enabling safe charging in sub-zero conditions. The 320Ah (~4,096Wh) can power a 12V compressor fridge, diesel heater, and 230V appliances for multiple days without shore power. The 640Ah (~8,192Wh) doubles that capacity for true gas-free, grid-free living.
Does this lithium battery system work with electric vehicle (EV) campervans? Yes. The 25A DC-DC charger is specifically rated for EV and hybrid campervans. It safely limits current draw to avoid overloading the vehicle's HV-to-LV converter and only activates in Drive or Ready mode. CCCAMPERS are experienced in EV auxiliary electrical integration to IMI TechSafe Level 3 standards — making us the most qualified campervan converters in the UK for EV electrical work.
Do I need an additional charger if my motorhome already has a mains hook-up converter? No. Most motorhomes manufactured from 2018 onwards are fitted with a factory 20A AC-to-DC mains converter. This is fully sufficient to charge the LiFePO4 battery bank via your existing shore power or hook-up connection — no additional mains charger is required.
Where is this heated lithium battery system installed? All installations are carried out in-house at CCCAMPERS' dedicated conversion facility: Woodside Business Park, Beach Hay, Bayton, Kidderminster, Worcestershire, DY14 9NE. Our AWS-certified, NCC Academy-trained, and IMI TechSafe Level 3 technicians complete the full supply, wiring, and commissioning.
Is this lithium battery installation compliant with UK leisure vehicle electrical standards? Yes. Every installation is hardwired to BS 7671 (18th Edition) and BS EN 1648-2 standards, with R10 chassis earth bonding and a 16A RCD breaker. This maintains full UK leisure vehicle insurance validity and NCC compliance. CCCAMPERS hold Approved Workshop Scheme (AWS) accreditation and NCC Academy certification.
