Hi All
I am in the process of installing 4x 200Ah Smart Lithium (in parallel). I don't have much space in the battery box - in fact it is very tight indeed. Ideally the batteries would be against each other with no space.
I have read in the lithium manual - about the recommended spacing between each battery. I have also aware the batteries will generate heat when being discharged or charged. It is my understanding the amount of heat produced is linked to the level fi charge / discharge.
My total capacity is 800Ah - and the maximum load will only ever be 125A (about 31A per battery)- for very short periods (3 or minutes) - and the maximum charge current will only ever peak at 70A (about 17A per battery). These seem, to me, to be very very low loads / charge currents for each battery to cope with compared to what they are capable of. And, as a result, the batteries will not heat up - and spacing in the box will not be a big issue.
Nearly every installation I see of Lithium, on boats, the batteries are all against each other. I have never seen anyone space them by the recommended space in the manual. I even see this on installations by Victron approved suppliers. It may be that every install I have seen is 'bad' - but no one seems to have any problems.
What do you think ? Must I space them - given the low discharge / charge currents ?
Thanks
Tim
