Battery dimensions ：Update battery display button and start button, Group size 27 (N70), 12 x 6.8 x 8 inches, Terminal Layout: Left: + Right: -. 12.8V 80AH 1300CCA.Tips: Please check battery size before purchasing. Battery voltage display button, do not allow series parallel use. Safety Performance:Lithium iron battery is light in weight and has high starting current; its weight is one-third of the general lead-acid battery, which can effectively reduce the weight of the front end of the car. The battery is equipped with BMS control circuit, the safety performance is completely better than ordinary lead-acid batteries. Starting Ability: high rate power imported lithium iron phosphate battery pack, starting ability than ordinary lead-acid battery starting ability is one times higher; ordinary starting battery is generally only 500CCA cold start current, lithium iron battery starting current up to 1000CCA or more. Low-Temperature Performance: excellent low-temperature performance, in the sub-zero environment can also be easily started, while the internal electrolyte of the ordinary battery is greatly affected by the temperature, below-zero start is very difficult; in the winter to better reflect the advantages of lithium iron battery. Maintenance Is Convenient: ordinary batteries do not have a BMS control board, it is very easy to forget to turn off the lights or stop and listen to music, long-term unused car battery damage, maintenance is relatively troublesome without regularity, lithium iron batteries have a comprehensive intelligent protection circuit, over-charging, over-discharging, over-voltage, over-current and other protections.
