Most people use lead-chemistry batteries and carrying around unneeded lead is both heavy and expensive. More importantly, **having more battery than you can charge fully and regularly** results in [[electrical:batterycide|battery murder]]. This is especially true for AGM batteries which typically have a //minimum// charging current requirement of C/5 (ie, 20A for 100Ah, 40A for 200Ah). It is a rare vandweller who actually charges their AGM to [[electrical:solar:charge_controller_setpoints|manufacturer specs]] and gets a full life from them. | Most people use lead-chemistry batteries and carrying around unneeded lead is both heavy and expensive.

Exotics like [[electrical:12v:deep_cycle_battery#lithium_chemistries|lithium]] and [[electrical:12v:deep_cycle_battery#carbon_foam_agm|carbon-foam]] aren't bothered by partial state of charge, but they are so expensive that buying too much is a self-limiting behavior. | Exotics like [[electrical:12v:deep_cycle_battery#lithium_chemistries|lithium]] and [[electrical:12v:deep_cycle_battery#carbon_foam_agm|carbon-foam]] aren't bothered by partial state of charge, but they are so expensive that buying too much is a self-limiting behavior. |
