Autohelm Power Consumption

There’s a 418 owner on the 418 owners FB page who is about to install an Efoy - I’m interested to follow. Patrick Laine of YouTube fame seemed happy with his. If / when I go extended ocean sailing this or probably a watt n sea will be what I opt for. Bother about the same price eg £££££££

For Mike & anyone else contemplating the LiFePO4 battery jump - re LiFePO4 cost.  My own experience is as follows.  I currently have 2 x 150AH for a total of 300Ah ( so 240AH usable to 80% DOD) for a cost of £655 each with configurable JBD Overkill BMS and Bluetooth connection for management.  Add a couple of hundred more for a programmable relay to sort connectivity with the alternator, plus revised cabling.  I did have a DC-DC charger in the mix initially to manage alternator load but ditched it as it introduced complexity and my 400 already has more than enough resistance in the cables to keep the alternator ticking along happily at a max of 61A and a temp of 55-70C.  My existing Sterling 3 way charger set to Gel settings is providing the charging at 14.1-14.3v that LiFePO4 is happy with.  I may yet add a 3rd LiFePO4 battery to give a total of 450AH but I still wouldn't hit £3K.

Mike I went with the ones from LifeBatteries. UK firm with a knowledgeable guy running it. Also called Mark by chance, no connection! Link to what I bought below.
