Before charging a battery, verify the required charging voltage, current limit, input voltage, thermal performance, and battery chemistry. For lithium batteries, use a suitable charging profile and an appropriate BMS. A BMS provides protection, but it does not replace correct charger settings. Never leave a DIY battery charging setup unattended.
