When tightening screw ends Headway specify tightening to 3Nm and maximum torque should not exceed 4Nm otherwise the cell could be damaged.

 

Warning - You should only attempt to construct your own battery pack if you have suitable electrical knowlegde. If you have no electrical experience we would recommend you consider purchasing a complete battery pack.
A Lithium battery bank you can grow on a budget that you can buy a cell every month That each time you have 4x of them can assemble them to make a 4x Cells 12V 15Ah String group

and still keep getting them each month

Every 4x months you can grow your Lithium Battery Group Clusters with a 15 extra Ah evey time you add a new group
15ah / 30 ah / 45ah / 60ah / 75ah / 90ah / 105ah

once you have 6 groups you can then use WC 110mm Soil Drain Soil pie to make them into a 12v 105ah Pipe module so you can move it around easy
and Srew Cap the pipe ends however in one of the caps has 2x Speakon 4 Pole connector sockets (allows you to Parallel Daisy chain 12v 105ah Pipe modules together yet also allows you to Parallel cell balance)

Reserved: Still editing
The pipe module if made a little longer could fit each 6 Groups of Battery's (12V 105ah yet due now there's 6 of them can now support a 2000W Inverter 6x 45AMPs = this 6 groups bank can now Handle 270 Amps loads)
And not just any inverter

We can go for the Parallel sync inverters that you can stack together to gain more AC watt outputs

(these will not work with non sync inverters these will make the magic blue bellow out of non sync inverter due they lacks the protection circuity + sync )

Now you are talking.

This I can build up slowly.

I wonder what their life cycles are though? Please forgive me if I missed it somewhere.

"Cycle Life: 2000 Cycles"
(yeh lead acids suck 200 - 500 cycles)

Lead acid battery life can be extended if you dont deep cycle them. Some lead acid batteries last many years.

But then again 2,000 cycles = about 5.5 years for the lithium battery. Not too bad.
