Why Choose MANLY’s 12V 50Ah Lithium Battery?

Optimized Operating Temperatures: Built to perform exceptionally well in challenging conditions, this battery thrives in both rugged and harsh environments. With an optimal temperature range of -20°F to +150°F, MANLY 50ah lithium battery outperform both sealed lead acid (SLA) and other lithium options. Please note: charging is not recommended below 32°F, while discharge and charge cut-offs stand at -4°F/-20°C and 23°F/-5°C respectively. The BMS high-temperature cut-off is set at 167°F / 75°C.

Unbeatable Energy Efficiency: Traditional lead-acid batteries generally offer a 70% energy efficiency rate, meaning you lose 30% of your energy during the recharge process. In stark contrast, MANLY’s 12v 50Ah lithium battery boasts an astounding 95% energy efficiency. This allows for quicker charging times and greater energy conservation.

Low Self-Discharge Rate: One of the key advantages of MANLY 12v 50ah lithium battery is its incredibly low self-discharge rate of just 2.5% per month at room temperature (77℉/25℃). This means that even if you haven’t used the battery for a year since your last outdoor escapade, it will retain over two-thirds of its original charge.

Lighter, longer-lasting, and more eco-friendly—MANLY 12V 50Ah Lithium Battery contains no acid or heavy metals, making it a safe, reliable, and sustainable choice for your power needs. Upgrade today and experience the future of energy storage.
