Balanced protection and battery voltage equalization to extend battery life. Aluminum-substrate heat dissipation for safer thermal management. Overcharge and overdischarge protection to prevent damaging charging or discharging; overcurrent protection guards against abnormally high current. Safety protection absorbs high voltage spikes, reduces MOSFET failure, and uses ultra-low on-resistance MOSFETs for efficient performance. Key attributes - Function: cell balance, voltage equalization, over/undercharge safeguards, current protection. - Material: aluminum-substrate for effective heat dissipation. - Performance: protection against voltage spikes with low on-resistance MOSFETs for reliability. - Compatibility: suitable for rechargeable battery packs requiring balance and safety protections. - Size: compact protection features integrated with the pack design. Use scenarios - In custom battery packs for RC vehicles, drones, and portable tools to maintain cell balance and protect from overcharge and high current. - In DIY energy storage or portable power banks where safe charging/discharging and spike protection are important. - In solar or off-grid battery systems to ensure safe operation, improved heat management, and extended pack life.
