Can a 12A Charger Charge a 20A Battery?
1 Answers
12A charger can charge a 20A battery. Here are the relevant details: No impact on the battery: A 48V 12A electric vehicle charger can be used to charge a 48V 20A electric vehicle battery. It has no adverse effect on the battery, but it may impose a heavier burden on the charger. Currently, if it's for temporary use, you can continue using this charger. However, if possible, it's recommended to purchase a higher-power charger with a current closer to that of the battery. Precautions: A charger with a lower ampere-hour (AH) rating can fully charge a battery with a higher AH rating, and may even overcharge it, though the charging process will be slower. Conversely, a charger with a higher AH rating will charge a battery with a lower AH rating faster but may not fully charge it.
