ProTek RC 2S High Current Charge/Balance Adapter (4mm to 5mm Solid Bullets) (10awg Wire) (24")
About this part
The ProTek R/C 2S High Current Charge/Balance Adapter is the solution you have been waiting for if you charge/discharge your 5mm bullet batteries at higher than normal amp rates, or need a heavy duty low resistance charge cable. Featuring huge 10awg wire at 24" length, gold plated 5mm bullets for the battery connection and 4mm bullet connectors for the charger connection, with an XH balance tap, this charge cable is one of a kind. The coiled jacket helps to keep the adapter flexible and tangle free and finishes off a package that will keep your work space clean and organized.
Features:
- Fits chargers that use 4mm bullet charging inputs
- Hi-Amp gold plated 5mm bullets for battery connection delivers higher amp carrying capacity
- Hi-Amp gold plated 4mm bullets on charger side
- 10awg wire to handle high current demands
- Coiled jacket helps to prevent tangles
- Length 24" (61cm)

Overall, these are trash. Too much wire braiding, inconsistent shrink tubing, and poor soldering throughout. I bought two sets because I didn't feel like building them, and am very easy on equipment/cables. - Solder joints broke after a few charges, there is too much solder and it's a cold solder joint on all connections. - The 4mm bullets fit poorly (tight) to start and quickly collapsed to the point of just falling out of the batteries. - The shrink tubing on the braiding is inconsistent and pulls on the small gauge wire, it's certainly going to fail at the balance connection to the charger. - I've had to re-solder the small gauge wire on both sets twice. The pro? It's motivated me to build a set that don't suck.
The white wire with the 2mm bullet could be longer. I ended up adding a 4 inch extension, so I could plug it into the battery less tension. Tension on the 2mm bullet wire will cause an early failure. Lastly, I use an icharger 406b with this charge lead. When charging the SAME battery with this lead, I am getting 3.4 mOhm per cell. With my home made lead, I am getting 1.8 mOhm per cell. Occasionally, cell 2 will drop to 1.0 mOhm per cell, with the protek lead. So, this leads me to believe there is probably a bad solder/bullet connection on one of the balance wires going to the +/-. For the price is is not terrible. It would have cost me more to buy all the stuff to make this one. I will probably end up redoing the solder joints, so see if I can fix the IR discrepancy with the protek lead.
I bought 2 of these leads, and used them for the second time tonight at a race. The first one the balance connector fell off. then the second one started reading my battiers as being unbalanced so the charger wouldnt charge my batteries anymore. Im surprised coming from Protek..
Great charging leads. had homemade ones before and these are much nicer and less money. unlike the another reviewer I have had no issues with resistance and I run an icharger aswell. buy with confidence.
Nice all in one cable. The connectors and jacketting are high quality and put together well. I just wish the balance lead on both ends were a touch longer. Especially on the battery end.
Reviewers largely agree the 2S charge/balance adapter has build quality problems. Recurring complaints include the braided or woven sleeving being bulky and stiff, inconsistent heat shrink, and tension on the small-gauge balance wire and 2mm bullet, which some report snapping or detaching after a few charges. Solder joints were described as cold or excessive by one reviewer. Several reviewers reported balance-related charging errors, including false unbalanced readings and an invalid cell count traced to swapped wires in one unit, and one reviewer measured higher cell resistance than with a homemade lead. Others found the cable functional and noted it costs less than building one. Common requests are a longer balance lead, especially at the battery end. Reviews are mixed, with several one-star and two-star ratings against a few high ratings.
- + Less expensive than building an equivalent lead
- + Connectors and jacketing feel well made to some owners
- + Works correctly on some units
- + All-in-one cable with a balance connector matching charger pin count
- − Braided or woven sleeving is bulky and stiff
- − Solder joints reported as cold or excessive
- − 2mm bullet and balance wire snapped or detached under tension
- − Balance wire too short, especially at the battery end
