    Big Power in a convenient package

    I need to replace a 200Ah battery on our caravan with something with more Ah's. The iTECH400X PRO is exactly the same size as our 200 AH, so it fits in the same enclosure, and gives twice as much storage. The Bluetooth feature means that I don't have to rely on the management system to let me know what the battery is doing, so it's a win-win for us.

    NGR. No Generator required in my RV

    My RV power and fridge upgrade is finally complete thanks to my new 400X battery . With ample power (120X and 400X) we have replaced our 3 way fridge with a Thetford 12 volt fridge which uses on average 45 A/H per day. 3 days of wet weather here in Ingham, most neighbours are running generators where as we will last 5 days without any sun or charging. Thank you Itechworld.
