Always use CC\u2011CV within the chemistry\u2019s voltage and temperature window.<\/p>\n<p><strong>Why does an LFP battery show half power but then die suddenly?<\/strong><\/p>\n<p>LFP\u2019s flat voltage curve complicates SOC estimation. Calibrate BMS with periodic full charge\/discharge cycles and monitor SoH trends to avoid sudden cutoffs.<\/p>\n<p><strong>Is it safe to run old and new batteries in parallel?<\/strong><\/p>\n<p>Avoid it. Differences in internal resistance above ~10% cause current imbalance that forces heat into the weaker pack.<\/p>\n<p><strong>How should we handle operations in \u221220\u00b0C conditions?<\/strong><\/p>\n<p>Where possible, use validated low\u2011temp packs and require auditable cold\u2011temperature test metadata. Some vendors report figures such as \u226580% usable capacity at \u221220\u00b0C in controlled trials; treat these as supplier-reported unless you can review raw thermal\/voltage traces, SOC windows, and sample size.<\/p>\n<p>If you\u2019re using standard packs: preheat to 20\u201325\u00b0C, insulate, and avoid high\u2011load maneuvers until telemetry confirms stable voltage recovery.<\/p>\n<p><strong>Is the premium cost for semi\u2011solid batteries worth it?<\/strong><\/p>\n<p>If a semi\u2011solid candidate delivers audited abuse\u2011test advantages, verified cycle life, and pack\u2011level Wh\/kg that meets your mission, it can reduce TCO by lowering failure incidence and increasing usable mission duration. Require supplier test summaries and independent lab certificates as part of procurement.<\/p>\n<p><strong>What should I do if a battery is swollen?<\/strong><\/p>\n<p>Retire it immediately. Swelling indicates internal gas generation from decomposition. Never puncture or compress it; follow your hazardous waste and battery recycling procedures and consult the supplier\u2019s MSDS for disposal instructions.<\/p>\n<div
