Model Number: HD-48F90-01 Brand Name: Haidi Key Specifications/Special Features: Special features:Nominal voltage: 48VNominal capacity: 90AhMaximum charging current: 180ACharge limit voltage: 58.4V

Discharge limit voltage: 40V

Dimensions: customized

Lifespan: up to 2000 cycles (while sealed lead-acid batteries only 300 cycles and NiMH batteries only 500 cycles)

Higher capacity and voltage (we can install single cells in series and in parallel and it can fully discharge, while SLA batteries only 70% to fully discharge)

More powerful (high discharge current, 1C continuous, 3C pulse for normal cells and 10C for special design)

Safe to use (never explode and stable in high temperature, so no temperature controller needed)

Light and small (1/2 size/weight of SLA batteries, 70% size/weight of NiMH/NiCd batteries)

No memory effect (it can be recharged anytime, no reduction of capacity)

Wide operating temperatures: -20 to 75°C

Eco-friendly (no lead or cadmium)

Can be charged by solar power
