Power pack to start boat engine ?

[stuartwineberg]

Have the bigger Halfords one for up too 3lt diesels. Now I no longer have the Sadler or the Landrover, I don't need it, but I do use it to charge the iPhone away from the grid. It does seem to use half its charge to get the iPhone back up to 100% - it always surprises me. The other thin is that it need about 3 or 4 volts left in the battery to trigger the failsafe, so if it's completely flat you're cattle trucked.

Mine has an override which I think bypasses that failsafe. Worked fine when there wasn’t enough battery in the car to light up the dials

However, having bought a NOCO pack to start my van with its 2L engine and discovered it was not big enough on frozen days, I have bought larger one for van, and decanted smaller one to the boat. Boat only has 1L engine and engine unlikely to need to be started when sea frozen.

Easier than sorting out my separate battery system to readily enable starting from leisure/cabin battery.
