Replacing lead acid battery with Lithium Ion battery

[D.A.(Tony)Stewart]

Klaus you are getting too pedantic. The logic is simple. Use half the energy to avoid stress at both ends of SOC to get 10 times the charge cycles gives you 5 times the life capacity. Chill man. Your mileage will vary depending on quality or C rate.

elsewhere only 250% gain but same idea using 20 to 80% but no data.. that's at Batt U site.
"Data suggests that maintaining a charge between 20% and 80% can help preserve battery health longer."

I wish to replace my electric wheelchair's lead acid battery 24V 12AH with Lithium ion battery. Please guide if I may face any problems? If yes What would be the ideal voltage for long endurance usage

Yes, as long as you pay attention to the voltage and discharge performance parameters, lithium batteries can completely replace lead-acid batteries. Compared with lead-acid batteries, lithium batteries have the advantages of high energy density and high cycle times, but the cost is relatively high, and lithium batteries need to be protected by a specific BMS.
If you replace the lead-acid battery with a lithium battery, you also need to use a specific lithium battery charger. The minimum charging voltage of a 24V lead-acid battery charger is around 18V, and the maximum charging voltage is 29.2V/27.6V. The minimum charging voltage of a 24V lithium battery charger is around 17.5V, and the maximum charging voltage is 29.4V. In addition, the trickle charging stage is also different.

You can clearly tell the difference between them.

 

[Calm down]

If it is an electric wheelchair for disabled people, I think using lead-acid batteries may be safer because you cannot let people with limited mobility escape when the battery loses control.
