Recommendations on charger for accessory battery (12v)?

I built a 12v (3 in series 3 parallel) lithium ion accessory battery for my bike lights and other accessories, but now I need a charger. Anyone have any recommendations? Searching online has been pretty not easy.

I've been searching on Amazon and this is the best I can find so far, but the reviews are pretty meh.

Any recommendations? I'd prefer to pay on the lower end if possible.

This will do the trick just fine.

Looks good thanks :thumb:
