Boat battery?
Car battery and a float charger?

70A eh?
How many ECU are you programming, about 40 a time?

Sorry, I don't understand. I am looking for a power supply capable of supplying a stable 13.8v with the potential for drawing up to 70amps. Are you offering this?

Afaik BMW only recommend 40A for coding.

I thought for e90 they recommend 70a? As far as I'm aware that doesn't mean a constant 70a - it depends on what it draws, I've heard a basic e90 can draw up to 60amp, a higher spec will obviously be more...

Im also looking into a power supply as well. I bought AA's tune recently with their Simon Tool & it was recommended that I connect my car to an external power source while the Simon Tool reads the ECU & uploads the tune file

I'd love your input! THanks!

I'm still looking for a cheap solution for this.

Bargain!

I use large PSU at 12v for my ham radio station but rarely need more than 30A at 12VDC.
These supplies typically run to about 120 or so so the above is good value from HK.

I did look at that however the output voltage only goes up to 13.2v - not the 13.8 as recommended
