• New batteries/accumulators are partially charged at the factory.
• Batteries/accumulators can only be operated with protective circuits. Without the use of protective circuits, balancers, and BMS, permanent damage to the batteries is highly likely.
• We recommend connecting the batteries by soldering. Soldering may damage the battery due to high temperatures.
