Powering a Greener Tomorrow

One Battery Platform.

Two Roads to Run On.

Backup power for homes, businesses, and telecom sites & Purpose-built lithium power for Bangladesh’s easy-bikes and auto rickshaws – rated for 6,000 full discharge cycles.

Why Choose GreenMax

GreenMax Energy builds LiFePO4 battery packs with a smart, actively-balancing BMS – used in home solar storage and in easy-bikes and auto rickshaws across Bangladesh. Same platform, one job either way: stable power through thousands of full discharge cycles, without degrading unevenly.

Why the battery underneath matters

Cheap packs skip active cell balancing, so one weak cell drags down the whole pack over time. GreenMax’s JK Smart Active Balance BMS redistributes charge between cells during charging, flags problems early via app or LCD, and shuts down safely instead of failing silently.

Is GreenMax a Chinese or Bangladeshi brand?

Both. Manufactured by Guangzhou Jieli (VIPOW) in China; imported, sold, and supported in Bangladesh entirely by Sihan Enterprise.

Same core platform (16S/51.2V and 20S/64V), configured differently for mounting and use.

Through Sihan Enterprise’s dealer network — see Contact, or Become a Dealer if you want to stock them.

Each cell is rated for 6,000 cycles; real-world lifespan depends on use, charging, and storage — see Warranty & Support.
