It's the only value that allows for complete BMS balancing and optimal capacity. What damages a battery is storing it at 100% or 0%, not fully charging it before use.\u003c\/p\u003e\n\n\u003ch3\u003e ➡️ Can I alternate between my original 53.6V charger and the 54.6V Source'IT charger?\u003c\/h3\u003e\n\n \u003cp\u003eYes. Perform at least one full charge to 54.6V every 2 to 3 weeks to allow the BMS \u003cstrong\u003eto balance\u003c\/strong\u003e . After the indicator light turns green, leave the charger connected for an additional 30 to 60 minutes.\u003c\/p\u003e\n\n\u003ch3\u003e ➡️ Is a 2A current sufficient?\u003c\/h3\u003e\n\n\u003cp\u003e Yes. 2A corresponds to a standard charge, but it's still 70% faster than the original charger. This doesn't cause your battery cells to heat up at all.\u003c\/p\u003e\n\n\u003ch3\u003e ➡️ How long does it take to charge a Navee ST3 PRO?\u003c\/h3\u003e\n\n\u003cp\u003e For a 12.5 Ah battery, expect approximately 6 to 6.5 hours. The last 30 minutes are often spent \u003cstrong\u003ebalancing\u003c\/strong\u003e the cells by the BMS.\u003c\/p\u003e\n\n\u003ch3\u003e ➡️ Should I unplug it as soon as the LED turns green?\u003c\/h3\u003e\n\n\u003cp\u003e Not immediately: the green LED indicates the end of the main charge, but the BMS continues internal balancing. Leaving it plugged in for an additional 30 to 60 minutes optimizes cell alignment and preserves battery life.\u003c\/p\u003e\n\n \u003ch3\u003e➡️ Can I use this charger with another Navee?\u003c\/h3\u003e\n\n\u003cp\u003e This model is optimized for the \u003cstrong\u003eNavee ST3 PRO\u003c\/strong\u003e .
