Hi guys. I'm trying to come up with a battery & charging plan for a little amplifier that i'm making. I'm looking at a 12(ish) volt system, so i'm thinking i'll probably start with 3 of the Panosonic NCR18650B in series to start, but may add another 3 series pack in parallel if the battery life isn't good enough. (If there is a different battery that would be better for my application please suggest it.) I see that there are protected and unprotected versions of these batteries. I was under the impression that I would need to use a BMS board to monitor and protect the individual cells in the pack, but is that really necessary if I use the protected versions that i have a built-in protection circuit?
Also, when it comes to charging: I'm hoping to find a charging system that can be internal, and that is capable of supplying the load while charging so that the amp can be used while charging is in progress. Most of what i'm finding online are chargers that would require me to remove the batteries for charging, or wall-pack types that wouldn't allow for charging & usage at the same time. I know that I could build one using one of the Maxim IC chips, but i'm really hoping to avoid that this round. Any advice you guys can offer on a charging board that would suit my purposes would be appreciated!
Thanks for your time and advice!
