- Charging LiFePO4 from your alternator: a practical guideA converter holds a voltage; a charger controls current and voltage. What to check before charging a lithium bank from an alternator, and how to pick…
- What is a DC-DC converter? Buck, boost and buck-boostA DC-DC converter turns one DC voltage into another without wasting the difference as heat. Buck, boost and buck-boost types and uses explained.
- 12 V, 24 V or 48 V battery system: which to choose?Pick a system voltage by inverter size, cable length and the equipment you own, with current and cable loss worked out for 12 V, 24 V and 48 V.
- LiFePO4 batteries in series and parallel: wiring guideSeries adds voltage, parallel adds capacity. Datasheet limits, matching, equal cables, fusing and charging for LiFePO4 banks, with worked examples.
- Charging LiFePO4 in cold weather: below 0 °C explainedLiFePO4 should not be charged below 0 °C unless warmed first. How low-temperature protection, self-heating batteries and winter installs work.
- How to size a LiFePO4 battery bank: Ah, Wh and runtimeWork out daily watt-hours, add inverter losses and days of autonomy, then convert to amp-hours at 12 V, 24 V or 48 V.
