Can the normal gate motor charge a lithium battery ?

I have been told and what I kind of know is that lithium charges different to SLA.

So does the BMS make the SLA charger now work or do you need a charger ?

BMS I learnt is to protect the battery so not sure if helps on charging ?

But this is still very very cool !!!

The response I got from one of the manufacturers was that they use them at home, thats about as technical response I could get.

What I can tell you is that a standard 7 amp/hr gate or alarm battery doesnt last after 4 days of ant stage of load shedding.

The alarm and gate chargers are trickle chargers at 13.8 VDC, some have 500mA charger currents and some have 750 mA 13.8 and I know of alarm system which has a dip switch to select between 500 mA (for 7 amp/hr FLA batteries) and 1 amp (for 18amp/hr FLA batteries) charge current depending on the battery used.

Lithium batteries charging and discharging is a little more complicated than that.

Once again I am brand new to all this and would encourage anyone who has the knowledge and experience to share the facts with us.
