48v Telecom lithium battery 250Ah work with inverter 5 modules in parallel

1. Quick Detail of 48v 250Ah Telecom battery:

Prismatic 50Ah LiFePO4 cells inside
Compact in size and light in weight
BMS manages to each cell for high reliability
Each module connected in parallel to get 250Ah capacity.
Extra long cycle life - 5 times life of lead acid battery and 2 times of NiMH battery
Extremely safe: No explosion, no fire under collision, over charge or short circuit

2. Features of lifepo4 battery pack:

1)High energy density, 170mAh/g
2)Light weight, about 1/3 the weight of lead-acid batteries
3)Environment-frendly, green battery: do not contain any heavy metal, rare metal, non-toxic, no pollution, accord with European ROHS standard, it is a green battery.
4)superior in safety: non-explosive in short circuit, over charged, outside damage etc.
5)No memory effect: can charge and discharge in any condition, no need to completely discharged or charged, do not effect it's quality.
6)Long cycle life: 2000 times cycles life (1C, ≥80% capacity) which is 7 times of lead acid battery
7)low self discharge : ≤3% of norminal capacity /month.
