Let customers speak for us
from 127 reviewsThis battery runs my lights, TV and decoder, Computer and monitor, speakers, internet, blender and all the other small draw items in my caravan. In 2 years I've had no problems and I'm happy. It's lying on the floor under the bed and being a LifePO I'm confident that it can't burst into flame and I sleep very well.
I'm traveling around southern Africa in the caravan and this is a very helpful power source, coupled with a 3000 watt inverter.
I do all my cooking on gas and stay in caravan parks which have electricity available, so I charge the battery through the inverter from the mains. Solar panels are big and clumsy to carry around - the smaller roll-up panels are not very efficient.
Received in time, installed and working very well.
