Yea. If your serious about this hobby you need to replace that [charger] ASAP anyway. You cant expect much from it (except it to be UL approved) given you got it (all) for $200. That maybe inpart why they are having [battery] issues to begin with. There are many to choose from but my budget minded opinion would be a Triton Jr.

ALWAYS keep an eye on any LiPo based power components and accessories.
