- High Energy Density
- Long Cycle Life
- High Safety Standards
- Stable Performance
Intelligent BMS for Complete Protection
Equipped with a 100A advanced BMS(Battery Management System), this 12V 100Ah lithium leisure battery safeguards your motorhome’s power setup from over-charging, over-discharging, over-current, overload, high/low temperatures, and short circuits.
- Max. continuous charge-/ discharge current: 100A
- Max. discharge current (1.2s): 300A ± 50A
Extreme Climate Performance
For UK trips in all seasons, the WattCycle 12V 100Ah lithium leisure battery is built to perform in challenging environments. It operates between –20 °C and 70 °C, with charging temperatures from 0 °C to 50 °C, making it reliable for both winter camping in the Highlands and summer coastal getaways in Cornwall.
Lightweight Drop-in Lead-Acid Upgrade
Weighing only 10.5 kg, the WattCycle 12V 100Ah lithium leisure battery delivers a much higher energy density (121.33 Wh/kg) compared to 12V 100Ah lead-acid batteries (27.40 Wh/kg). It’s the ideal drop-in replacement, freeing up valuable payload and storage space in your motorhome or campervan.
Expandable Energy – Up to 20.48kWh
For longer off-grid stays, multiple batteries can be connected in 4P4S configuration, creating a 48V 400Ah system with a massive 20.48 kWh energy bank and 20.48 kW continuous output. Perfect for powering solar-powered campervans, larger motorhomes, or full caravan setups.
