Utilising robust long life cell management technology, the Advanced 100 Leisure Battery is ideal for delivering the flexible power demands of varied leisure environments, from marine river boats and canal barges, to road adventurers, including campervan, motorhome and caravanning enthusiasts. The Advanced 100 offers a 1.2kWh bank of energy storage in a small and lightweight battery form factor.

Thanks to the Teconnex Power Advanced 100's ability to recharge from solar and wind installations (in addition to standard charging from a traditional "mains connected" electric source), our battery can provide operating benefits for small power needs in static off-grid environments. This includes domestic and small business settings such as beach huts, garden rooms, car ports, storage sheds, and small agriculture units.

Teconnex Power leisure batteries are not just 'advanced' - they are smart too! This is thanks to the intelligent Battery Management System (BMS) which ensures continual optimal performance of the platform. Our BMS offers Advanced 100 users flexible management and control via Bluetooth App, which is available for both Android or Apple IOS compatible devices.

  • Industry-leading battery life - Lasts more than 3x longer than typical lead-acid batteries.
  • Super lightweight - Approximately ⅓ of the weight of a lead-acid battery at only 11.4kg.
  • Long-term performance - Grade A assured LiFePO4 cells provide long-term product performance.
  • Safety features - Inbuilt battery management system protects against overcharging, deep discharging, overheating and short-circuiting.
  • Added control - Clear visibility and user control via the Bluetooth-enabled Android and Apple IOS app.
  • High-quality components - Made from the best materials available for quality you can rely on.

Made in the UK - Designed and developed in the UK by Teconnex's expert team of engineers.
