LiTime 12V 100Ah LiFePO4 Battery vs NewtiPower 48V 100Ah LiFePO4 Battery

These are not substitutes: the LiTime is a 12.8V 100Ah battery (1.28kWh) and the NewtiPower is a 48V 100Ah battery (about 5.12kWh), four times the energy. Buy the LiTime for a 12V system in a Group 27 compartment, such as an RV, kayak or trolling motor, and for the Bluetooth app that shows state of charge. Buy the NewtiPower when you run a 48V system, like a golf cart or a larger off-grid inverter, and want one battery instead of four 12V units in series. The LiTime is light at about 22.6 lbs and has a strong owner record; the NewtiPower is about 90 lbs and its 200A BMS and 10,000-cycle claim are less proven.

• Choose the LiTime if you need a 12V drop-in replacement that fits a Group 27 tray and you want live status on your phone.
• Choose the NewtiPower if your system runs at 48V and you want one battery with a 200A BMS instead of wiring four 12V batteries in series.
