Neexgent Lifepo4 Litium Powerwall 48v 200ah Lithium-ion Batteries For House Solar System

• High cycle life
4000 cycles @80% DoD for effectively lower total of ownership cost

• Longer service life
Low maintenance batteries with stable chemistry.

• Built in circuit protection
Battery Management System (BMS) is incorporated against abuse.

• Better storage
up to 6 months thanks to its extremely low self 
discharge (LSD) rate and no risk of sulphation.

• Quickly recharge
Save time and increase productivity with less down 
time thanks to superior charge/discharge efficiency.

• Extreme heat tolerance
Suitable for use in a wider range of applications where 
ambient temperature is unusually high: up to +60°C.

• Lightweight
Lithium batteries provide more Wh/Kg while also 
being up to 1/3 the weight of its SLA equivalent.
