Charging Notice: Charger is not included with this battery. This battery must be charged with a lithium-compatible charger only. Do NOT use a lead-acid charger. Using an incompatible charger may cause improper charging, trigger BMS protection, or damage the battery.
Compatibility Notice: This product is NOT a starter battery and is not suitable for generators, motorcycles, ATVs, lawn mowers, or other starting applications. Please verify the battery dimensions and device compatibility.
[Low Temp Cut-Off] DC HUSE 12V 30ah mini lifepo4 battery has upgraded Low Temperature Protection. When the temperature sensor of 30Ah lifepo4 detects that the temperature is below 19.4, the BMS will cut off the charging function, cut off the discharge when it is below -4, and automatically recover after the temperature rises to 32. Effectively protect the 12V 30Ah battery and extend the battery life
Replacement 35AH AGM Battery: Designed for Kid Ride on Toy, emergency lighting, RVs, solar systems, lighting, alarm systems, and outdoor camping applications. If used for a 24-volt electric wheelchair, two batteries need to be connected in series.
Note: Not suitable as a starting battery. Do NOT use for motorcycles, jet skis, snowmobiles, or UPS systems.
[30A BMS Protection] Built in 30A BMS Management systemwhich protects 12 volt lithium battery from over charger and discharge, over current, short circuiting, cell voltage self balance for increased performance and longer life.
[A Grade Cell & 4000+ Deep Cycle] 12V Deep Cycle Battery Battery is made of 100% Grade-A Cell, whhich has higher energy density, more stable performance and greater power. The cells inside the battery are UL, IEC tested and CE, RoHS certified, providing the highest level of safety for you. Our Lithium Iron Phosphate (LiFePO4) battery can be recycled up to 15000 times and provide up to 10 years of service life.
[Capacity expansion] lithium batteries can be used not only in parallel but also in series, such as 2P2S, 2P3S, 2P4S, 3P2S, 4P2S. Please note that the number of batteries connected in series and parallel at the same time cannot exceed 8.
It is recommended that high-current devices such as trolling motors be connected using ring terminals to avoid alligator clips, which may cause poor contact and overheating. Before use, check the terminals for rust or oxidation, and clean them regularly to maintain good contact.
