can we join lithium battery with lead acid battery in series? Answered

we are working on project and we need more power in less cost so lead acid battery is compulsion but we want to add lipo battery with it to get more power. can we do that?

NO! Never mix battery types. Once the SLA battery dies the lithium battery will continue discharging, possibly causing the SLA to go into voltage reversal resulting in a rupture. Batteries, especially lithium batteries, need to be paired together in matched sets. Meaning same type and from the same manufacture. This is to ensure that all batteries are at the same approximate state of charge to minimize voltage reversal during usage.
