Hello all,
I bought a 134N3P based Lithium battery charger board to reuse few lithium batteries I had laying around.
One battery was rated for 3.7V while another was rated for 3.85V. I was able to charge and use the 3.7V battery with the module. Before connecting the 3.85V battery with the charging module, I wanted to check if it is safe to charge it with the same board since the voltage is rated 0.15V higher than the other.
I don't have any prior experience working with batteries.
Please guide me on the above issue.
Thanks in advance.

Try it and see.
Plug the multimeter into it and see what the cut off is.
I'd be keeping a close eye on any $2.00 charge module just the same.
Doubt one could ever leave it unattended.

Be careful with the 1A charge current though.......:eek:........battery university web site will give you best advice.

Thanks for the reply.
I will refer to the battery university website once before connecting it to the module.
