Not all Rolls are monobloc, they do a big range in dual container where they put the 2v cells in series to make up banks in a separate extra container.  To move mine (6V@ 123kg) I take them out of the case and move the individual 2v cells, then rebuild the bank.

Rolls are normally rated at C20 so my 673ah odd goes down to 458ah at C5.  When I turn on the combination oven and the inverter is at full chat it pulls 125 amps from the battery which takes it down to C3 which is 382ah.  We were supposed to have a gas oven but somehow things got changed and the battery bank didn't get uprated.   facepalm

He'll soon get round to upgrading the batteries... When he realises each Sunday roast is costing 54p in free electric but costing 50 in reduced battery life expectancy Shocked.  Better still, save those batteries and go out to a local pub for lunch... it'll be cheaper.  Grin

Sunday Roast,   facepalm

I should be so lucky.   flyingpig

I normally have a liquid Sunday lunch, dinner, supper combined, hic.

Happily at present the offending item is run off shore power, it only becomes a problem when that is disconnected.  In order to mitigate any interest from the RSPCB I have to start the 24v diesel charger to float some of the load, least I hope/think that's what it does?

New cells should be here any day  tumble

I've been on the verge, several times, of ordering a SmartGauge. Is there anyone "in the know" who has any idea if it's likely to be developed in the near future? I'm particularly thinking about some sort of output that can be logged  police

Well they're here and we'll see what happens  tumble
Voltage and SG checked on arrival - seem to fall into two camps. Seven cells at 2.13V/SG 127_, five cells at 2.08/SG 1.225. Nice yellow tops so we can look inside  faint
The cables will be shortened when they move to their permanent position  police

Yes, they are, but I'm a bit ashamed that I didn't give them a bit of a polish  facepalm

I must confess, I polish my batteries.

They have for three years been in the wheelhouse, having not got round to making the tray for them to sit on in the engine room.

But now, their home is complete and how happy they are down there so neatly nestled between the fuel tanks and the engine.  I do just have to keep nipping down there to see if they need anything and yes, just a quick wipe over, oh no, that one at the back needs tucking in..... facepalm

Sorry,

Billy the Barge,

I know that a 48v ones is coming.

Daftlad, sorry only just noticed your question. We were a bit concerned about the fact that there seemed to be two distinct voltages/SGs but after lots of charging they have equalised. We haven't really discharged them very much or subjected them to high loads but so far so good  faint
