3.   Instruction

1. Positive electrode plates

Positive plates of Good Price E-bike 48v/24v Electric Bike Battery 72v 20ah are made of lead –calcium alloy with special chemical formula

2. Negative Electode plates

Negative plates of Good Price E-bike 48v/24v Electric Bike Battery 72v 20ah are made of lead – chemical formula

3. separator

The glass – fibre separator in Good Price E-bike 48v/24v Electric Bike Battery 72v 20ah are made with advanced technology –this high porosity of the separators retains adequate electrolyte for reaction with active material of the plates .

4.safe valve

The valve system of Good Price E-bike 48v/24v Electric Bike Battery 72v 20ah which operater from 1 psi to 6psi (0.07-0.43kg/cm3) is designed to release excess gas and keep the internal pressure within the optimum range of safety .it protects the negative plates from contamination from oxygen in the air valve are 100%visually inspected during battery production

If the internal pressure is increased to an abnormal level during overcharge ,the safety valve ill be opened to release gas . it thus eliminates the danger of rupture .once it has opened m it automatically closed in preparetion for future excessive increase in pressure.

5. Terminal

Depending on the battery model in MICRO series ,the terminals may b e fasten type , bolt –and nut type , pressure contact type ,cable –and connector type or other special types

Terminals of MEDIUM series and MACRO series are threaded –insertion type of bolt –and nuts types

Construction of threaded-insert strut

6.case

For 6v ,8v and 12v batteries ,standard container are manufactured from ABS plastic resin (UL94HB),It is optional to use flame retardant ABS plastic resin (ul94vo)

Each 6v battery has 3cells .8v battery have 4cells and 12vbattery has 6cells

7Epoxy

The ABS plastic cover and container of Good Price E-bike 48v/24v Electric Bike Battery 72v 20ah are sealed by a special epoxy that is acid resistant.
