 ====== Overbanking ======
-Overbanking means having a battery bank oversized compared to available solar-only charging power.
+//Overbanking// means having a battery bank oversized compared to charging power (particularly in solar-only scenarios).
-The [[electrical:solar:panel-bank_ratio|solar:battery ratio]] might be something like 1:2.
+The [[electrical:solar:panel-bank_ratio|solar:battery ratio]] might be something like 1:2.  Overbanking is the opposite of [[electrical:solar:overpaneling|overpaneling]].
-[[electrical:12v:lifepo4_batteries_thread|Lithium]] chemistries are not bothered by partial state of charge so overbanking is a non-issue for them.  The camper might have a lot of lithium capacity to take advantage of [[electrical:12v:alternator|alternator charging]] or [[electrical:shore_power|shore power]] charging (via [[electrical:converter|converter]] or stand-alone charger).

-harmful effects
+===== harmful effects =====
+Problems can crop up when a 'dweller unintentionally overbanks:  "Hi guys!  I just bought 400Ah of AGM batteries and a 100w solar setup!"
+Unintentionally overbanked designs are also found where a 'dweller wants to run large [[electrical:inverter|inverter]] loads and forgets how much power it takes to **recharge the batteries fully every day**.  Failure to recharge fully leads to [[electrical:batterycide|battery murder]].
