We can design and give professional suggestion from swith power to batteries with our years battery expertise on different data, parameters, requirements according to you and your customer's requirement.
Q28: How to charge the battery?
A28: please use a specified lithium ion battery charger;
Q29: what’s the difference of your battery charger?
A29: each lithium ion battery factory has it’s typical design requirement for it’s batteries. Un-matched well charger might not charge your battery full and it’s charger protection range is a little different also.
Q30: what’s your battery charger charging method?
A30: our battery charging method is CC-CV. Constand current to charge the battery to 4.2v/cell, then charger will automatically shift to constant voltage charging.
Q31: what’s your battery charging voltage?
A31: this is a very good question. Generally, we set the battery charging voltage at 4.2v. for some high voltage battery cells, we’d use 4.25v 5% accuracy to charge battery. So it can give a fast charging.
Q32: is that a high charging voltage give any damage to battery?
A32: yes, absolutely true. Normal battery cells can not use 4.25v or 4.3v high charging voltage. Higher charging voltage will give a fast charge, but will damage battery cell if not be applied to.
