1. the voltage is too high, take the 36V charger to do the case, the lead-acid battery charger charging voltage is the lowest 41.4v-44.5V, the lithium can not exceed the 42.5V, otherwise the battery will end the life early, the weight will explode.

2. the constant current and constant voltage charging characteristics of Li ion battery only need two segment charger. The three lead acid is not suitable for .

The fast charging station on the 3 Street must not charge lithium batteries, only suitable for lead acid.

4. if the emergency charge is charged. Take the same type of lead acid charger. Never be full.

The lithium battery charger used in lead-acid batteries will be under charge. Lithium batteries will be overcharged with a lead-acid charger. So each use is better.
