I have purchased the following from Itechworld
2 x 120x Lithium Batteries
1 x 40 amp Dc Dc charger
1x 500 amp battery monitor
1 x 240 / 12 volt 40 amp battery charger
I live in Brisbane and delivery is about 7 days.
All phone calls and emails are always answered
Information is given in layman terms for easy understanding and not rushed.
These guys are great doing business with. Not affiliated to the company in any way.
By the way I have a Itechworld 120x lithium in the tug for the last 18 months running a 75 lt fridge being charged with Victron solar ppt and Dc Dc charger.
All the above are working well with no problems yet
Hope this helps
