Battery Upgrade... Drop in?

[Peregrinator]

There is a lot of talk on forums about "Drop In" Battery Upgrades, and people who actually understand these things know that the suppliers who claim their Lithium batteries are "Drop In" upgrades are talking out their posteriors (unless the motorhome in question happened to have been upgraded in the past with updated chargers, maybe monitors as well, or is very new and up to date).

This would be my reality of a "drop in" Battery Upgrade...
Mismatched/Unoptimised cabled 170Ah worth of basic Lead Acid Batteries at 10AM

Matched and Optimized pair of 160Ah (so 320Ah worth) of Lead Carbon batteries at 1PM

No significant changes made to the cabling (just remade terminals and connected in the correct manner) and no changes needed to the battery enclosure apart from repositioning the floor locking brackets
So easily more than doubled the usable capacity of the Motorhome Leisure Battery system with 320Ah of Lead Carbon loveliness at no more than the price of a single basic 100Ah Lithium, and with no additional changes demanded (unlike the Lithium).
What's not to like

"What's not to like" four times the weight, and it gives you 160Ah at 50%, shocked at that first photo, well done on a good job.

Lead Carbon is NOT limited to 50%, so get rid of that misconception for a start.
