hello all

picked the kontiki up on the 1st of dec and the dealer informed me that i had 2x110ah leisure batteries(bit of a bonus thought i only had one)
so i thought ok lets try 12v instead of an inverter.so i looked at the tellies in the bedrooms and found 1 with a dc input,built in freeview and dvd and it's a decent size 24"and it only uses 33w. had a root through the caravan stuff and found out that the bush sat receiver is dc as well,uses 7w,so am i right in thinking that i should get at least a couple of nights using this combi plus 12v lights and blown air heating using gas and lowest setting for blower

40 watts is around 3.3amps so that wont be a real problem....around 33hrs continuous tv and digi.

The heater blower will be the one to watch......even on a low speed it will eat amps.
saying that, the fan should be thermostatic and once the van is up to your chosen preset temp it shouls then just cycle on and off as needed.

Check the DC required by the TVs is 12 volts. Hard to tell how long your batteries will last, there are many variables, but if you don't have LED lighting then watching the TV in the dark would be recommended as the lights could be the biggest drain on power.

We have a sky pace box and use it regularly doesn't drain the batteries to much and the solar panel recharges as soon as the sun gets up.

2x 110amp/hour batteries will give about 110amp/hours usable charge when they are new. This drops as the batteries age or if they get damaged by over discharging them or them freezing etc.

thanks for all your replies
after a lot of reading of posts on this forum i am pretty sure that 12v is the way to go.will probably go down the solar panel route as well,i've booked to go to the chester rally at easter so if i haven't fitted solar by then i will be looking for advice.
thanks again and merry christmas everyone

LED lighting is essential.

The next variable you can't change is heating. That can be quite a drain in very cold weather.

Unless you have square eyes the TV will not figure much in your battery drain.

at least changing the bulbs for LED ones doesnt have to be expensive. you can get them from 70p each upwards on ebay
