【Upgraded 100A BMS for Trolling Motor】The Power Queen 12.8V100Ah low-temp lithium battery is equipped with a upgraded 100A high quality BMS that can endure a higher current from loads. The new BMS can withstand 500A current in 1 Second. Can be used to power for 12V-36V trolling motor with 30-120lbs thrust. Perfect for powering for trolling motor and electric fishing equipment like fish finder, GPS, sonar and etc. 【Low Temperature Cut Off】Upgraded BMS with low temperature sensor will cut off the charging process automatically when the battery was connected to a charging source and the cell’s temperature is lower than 32℉. Once the battery cells temperature is higher than 32℉, the BMS will resume the charging process and starts charging the batteries. Keeping the battery safe from being damaged even in cold weather. 【Grade A Battery Cells】Power Queen 12.8V100Ah low-temp LiFePO4 battery are made with high quality grade A LiFePO4 battery cells that have up to 10-year lifespan, with 4000+ cycles @100% DOD, 6000 cycles @80% DOD, 15000 cycles @60% DOD. On the other hand, AGM/SLA/FLA batteries typically only last for 3 years with 200-500 cycles. The Power Queen battery will provide 3 times lifespan and 4 times cycle times, a truly trustworthy deep cycle battery. 【Max. 20.48KWH Capacity Expansion & 1/3 Light Weight】Power Queen 12.8V 100Ah low-temp LiFePO4 battery has 1280Wh energy. Allows maximum extension up to 4S4P to get 48V(51.2V) 400Ah battery bank, and it can provide 20.48 kWh energy (4P4S) that could be widely used for outdoor, RV and solar systems. Meanwhile, Power Queen 12.8V 100Ah low-temp LiFePO4 Battery is only about 23.85lb which is smaller and 2/3 lighter than the lead-acid battery at the same capacity. 【10-year Lifespan & Up to 15000 Cycles】The lifespan of the Power Queen upgraded low-temp 12V 100Ah LiFePO4 Battery can reach up to 10 years. We offer a 5-year warranty and 24 hrs customer service. Besides, it is recommended to charge the battery at 14.6V charging voltage and 20A charging current, which takes about 100Ah/20A=5hrs to charge the battery fully. 【SPECIFICALLY DESIGNED FOR LIFEPO4 BATTERY】Power Queen 14.6V 20A LiFePO4 lithium batteries smart charger is uniquely designed for 12.8V LiFePO4 batteries, implementing the special 2-stage constant current/constant voltage (CC/CV) charge algorithm with smart LED indicators. This charger has a specific Pre-Charge function, which is designed to activate all types of BMS by allowing current into lithium batteries reading from down to 0V. 【HIGH-EFFICIENCY CHARGING】With a constant current of 20A and a constant voltage around 14.6V, it’s Ideal for LiFePO4 batteries 20 amp hours and above. Only needs 5 hours of fast charging time to fully charge a 12V 100Ah LiFePO4 battery compared with 3 amps multi-charger which needs 33 hours to fully charge a 100Ah battery. 【MULTIPLE PROTECTION】Power Queen 14.6V 20A LiFePO4 lithium batteries charger has multiple protection, such as over-temperature protection, output short-circuit protection, reverse polarity connection protection, and output over-voltage protection to prevent damage from faulty operation. 【EASY OPERATION & VISIBLE INDICATOR】Connected + and – of the charger to the battery as + to +, – to -. Then plug in the input cable to the charger and connect it to the input power. Intuitive LED indicators to provide visual charging state feedback and diagnostic information. 【PREMIUM QUALITY】Our LiFePO4 lithium batteries charger is made of aluminum alloy with surface oxidation treatment, high hardness, anti-oxidation, the built-in cooling fan keeps the charger itself cool. Heat dissipations protect your charger and battery. It’s safe in charging.
