How to choose the right car charger: What is the charger voltage of the original lithium battery? Just buy at the same voltage. 3 string ternary lithium battery selects 12.6V charger 4 string lithium iron phosphate batteries choose 14.6V charger 4 string ternary lithium battery selects 16.8V charger 5 string ternary lithium battery selects 21V charger 12V lead-acid battery (battery of car) choose 14.4V charger
