-🔋-【Usage Guidelines】▶Voltage of your controller: 48V/52V,▶Rated current of your controller: ≤ 30A,▶Your motor wattage: 0-1000W,▶Whether the b-attery size(10.4*5.5*3.7 inches) is suitable for your b-attery case.The accessories are all separate, making it convenient for customers to DIY Design/Upgrade devices themselves.
-🔋-【30A BMS】48V 20Ah LiFePO4 B-attery is equipped with a 30A BMS b-attery management system, effectively preventing overcharging, over-discharging, overheating, or short circuits to extend b-attery life. During daily use, a more professional and efficient b-attery connection method reduces b-attery wear, providing riders with a stable and reliable power supply.
-🔋-【LiFePO4 B-attery Features】It's the safest Lithium b-attery type.The maximum voltage of lithium iron phosphate at full charge is 3.65v. After the b-attery is fully charged and powered off, it is normal for the voltage to fall back to 3.35v or above. If the static state drops to 3.32 or below, it indicates severe b-attery loss.53.6v≤voltage<58.4v, B-attery capacity 99%-100%,48V LiFePO4 B-attery voltage in the range of 53.6v - 58.4v is normal.
-🔋-【Service】3*Months F-ree R-eturn / R-eplacements/ 12*Month Service,Package is damaged due to logistics/Package has not arrived/B-attery does not work/B-attery questions/don't know how to use it.etc.Please contact us at the first time, we will be responsible for the product and help you faster!Good communication can better solve problems.How to contact us from your order: Click Account&Lists→Orders→Get help with order→(Enter information)→Send e-mail.
