Thread: switching to Lithium

No more lithium goodness……

The defer drove out the gate with new owners.

Looking back, soooo glad we upgraded to lithium before our trip…..certainly set and forget. Was thinking 200ah was going to be a bit short on capacity…..nah, easily covered our needs for 2.5 years.

If we had of stayed with AGM’s we would have struggled with capacity especially when cooking with induction, would have had to carry extra solar and recon i would have been watching capacity every other day. Plus we saved a ton of weight as we were weighing in at 3100kg

Hi Loanrangie, you did not double your capacity.

A 100Ah lead acid battery has the same capacity as a 100Ah lithium.

The only time there is a difference in capacity is when one of them is limited to 20% SoD, which many lithium batteries are, just like older AGMs were.

But many AGMs today are capable of SAFELY supplying 100% of their capacity. Simply check the battery MANUFACTURERS web site for correct specs.

Heaps of lithium battery sellers tell you, you can only use 50% of a lead acid battery's capacity. This is nothing more than total B/S.

What you did save on was weight, but you will most likely take much longer to recharge the lithium batteries.
