Lead acide battery VS. Topband LiFePO4 battery
Item Lead acid battery LiFePO4 battery Comparison results
wh/kg 30-45 100-150 LiFePO4 battery is 1/3 weight of lead acid battery
wh/L 60-80 200-250 LiFePO4 battery is 1/2 volume of lead acid battery
    conclusion 1 LiFePO4 battery has higher energy density than that of lead acid battery.
cycle life 300-500cycles 2000cycles @80% DOD
1500cycles @100% DOD
LiFePO4 battery's life cycle is 5times of that of lead acid battery, and more cycles at deep discharge
    conclusion 2 LiFePO4 battery has much better cycle life.
charge rate ≤0.3C 0.5-1C LiFePO4 battery can bare quick charge, eg., 2hs full charge for LiFePO4 battery, while more than 6hs for lead acid battery.
discharge rate 3-5C,only 30%-40% capacity release under 3C discharge 3-10C, 80%-90% capacity release under 3C discharge LiFePO4 battery support high rate discharge, and more capcity release under high rate discharge
    conclusion 3 LiFePO4 battery has higher charge & discharge rate
self-discharge rate 3-10% <1.5% lead acid battery will be useless for long time storage, LiFePO4 battery can stock for long time
    conclusion 4 LiFePO4 battery has lower self-discharge rate
pollution Pb( against Rohs) N/A  
    conclusion 5 LiFePO4 is more eco-friendly
maitenance need fill water or mantain constantly free maitenance  
    conclusion 6 LiFePO4 need no maitenance
protection NA BMS  
    conclusion 7 LiFePO4 has built in BMS for better control
optional feature   bluetooth connection Topband LiFePO4 allow users read battery info.
    conclusion 8 Topband LiFePO4 support bluetooth connection
warranty 12-18months 24months  
    conclusion 9 Topband LiFePO4 has longer warranty
price lower higher  
    conclusion 10 LiFePO4 is higher in price
Summary LiFePO4 battery meets the trend of development
  LiFePO4 battery is better than lead acid battery from different point of view, except for price.
