Beginner’s Guide to RC – Explaining Battery Connectors and Balance Plugs
NiMh and NiCd batteries were pretty easy to charge and use; hook the clips up to the positive and negative terminals and hit charge. There were no balancing ports (except during discharge) and we didn’t worry too much about overcharging; the chargers did a great job of keeping track of the pack’s condition.
LiPos, on the other hand, require a bit more during the charging process. Not only do you have to make sure your charging plug is correct but, ideally, you want to make sure that you have the right balance plug as well (you are balancing your LiPos, aren’t you?). Since there isn’t really a standardized plug, you could have one of several different types of plugs attached to your pack. This can be confusing, but thankfully CompetitionX is here to give you the lowdown on the most common connectors and balance plugs on the market.
There may also be a chance that you have several different balance ports on several different batteries. This can be problem when charging unless you purchase several different balance boards that match the balance plugs you have. There is an excellent solution, however. You can pick up one of Hitec RCD’s Universal Balancing Adapter. This balance adapter (or balance board) works with all the major brand of LiPo batteries and can charge from 2S-6S packs. It also has ports (in the 2S-6S range) for JST-EH, Thunder Power, JST-XH and Hyperion (or Polyquest) plugs! I have 3 of these and absolutely LOVE them!
Below is a list of the most common connectors and balance plugs on the market right now. Hope this helps.
