Well, we should mainly use solar to charge our batteries, right? Sometimes we just need this little bit of extra help to charge our cells from the grid. Some of these chargers below can actually hook up to a DC source and charge form another battery for example.
Liitokala Lii-500 NiCd/NiMH/Li-ion charger
I’m using this charger for over a year now and am pretty happy with it. I handles all kind of cells and measures capacity and also internal resistance. It can be powered from any 12V DC source (but a power supply is also included)

54.6V 5A Smart Lithium Battery Charger For 48V Battery Systems.
The charger does not seem to deliver 5A but even with the 3.7A I measured, it’s a great little emergency charger for your 48V battery pack. I used it twice now and it works with no problem.
Also, it delivers 54.6V constant voltage so you cannot overcharge your battery at all!
