4.2Charging with Solar
Check the solar regulator you intend to use has a dedicated lithium charge setting that meets the above
charging requirements. A solar regulator without a lithium charge setting may be used to charge the TOPBAND
series battery. However, it must be set to charge no higher than58.4V and then MUST be switched off once the
TOPBAND series battery is fully charged. DO NOT leave a solar regulator switched on without a suitable lithium
charge setting once the battery is fully charged.
4.3Charging with an Alternator via a DC-DC Charger
Check the DC-DC Charger you intend to use has a dedicated lithium charge setting that meets the above
charging requirements. A DC-DC charger without a lithium charge setting may be used to charge the TOPBAND
series battery. However, it must be set to charge no higher than 58.4V and then MUST be switched off once
the TOPBAND series battery is fully charged. DO NOT leave a DC-DC charger switched on without a suitable
lithium charge setting once the battery is fully charged.
4.4 Recommended charging voltage
The recommended charging voltage is set between 55.2V and 57.6V. It is strongly recommended that the
special charger for lithium battery be used to fully charge the battery. At the same time, according to the actual
situation, the AGM charger can also be used to charge the battery, which can achieve different effects.
4.5 Equilibrium
When the battery is charged close to SOC100%, the voltage difference between the cells will gradually expand
due to the chemical characteristics of the lithium battery. In order to make each cell have the same capacity,
the cells with slightly higher capacity will choose "blood loss", so that the remaining cells can catch up.
5 Battery Recyclable
Topband® Lithium-Ion batteries are recyclable and should not be disposed of as household or landfill waste. If
you need assistance in recycling your battery, contact your dealer or Topband’s technical support engineers as
outlined at the front of this manual.
