Disconnect all loads and chargers from the battery terminals, allow the battery to rest for at least 30 minutes, and the voltage should automatically recover to above 11.8V (for 12V formats). Then, fully recharge the battery.
Yes, but you must only connect batteries of the exact same model and specifications, fully charge each individually before connecting, and follow the specific limits outlined in your manual (e.g., maximum 4 series and 4 parallel for standard 12V models).
It is highly recommended to use a dedicated Lithium Iron Phosphate (LiFePO4) battery charger programmed with the appropriate voltage limits (e.g., 14.6V for 12V models or 29.2V for 24V models).
Store the battery at a 50% charge level in a climate-controlled environment between 10°C to 35°C (50°F to 95°F), and recharge it every three months to ensure longevity and cell health.
