ProTek RC 2S Charge/Balance Adapter (4mm to 5mm Bullet Connectors)
About this part
This is a heavy duty 2S hard case lithium polymer battery charge/balance adapter lead from ProTek R/C. This 13" long charge lead allows you to plug a 2S battery with 5mm female bullet connectors directly to your charger, eliminating the need for a balance board!
This adapter lead features 4mm banana plugs on the charger end, and 5mm banana plugs on the battery end, connected with 14awg wire. The balance wires include a 2mm banana plug on the battery end, with a 7-pin XH plug connected with 22awg wire for balancing that is plugged directly into the 6S balance port in the charger. This charge lead is specifically designed to connect a ProTek R/C 2S LiPo hard pack with 5mm connectors to ProTek R/C chargers, but will also work with any charger that uses 4mm bullet connectors for output, and has a 7-pin (6S) XH balance port.
ProTek R/C is an AMain Sports & Hobbies brand.

Nice durable leads. Not expensive, but keep in mind when charging especially at high amps you want your leads to be 12 gauge or larger. These are amazing for what they are though, and they deserve 5 stars.
One of the wires came off after only a couple months of use. Very poor quality.
Worked without issues. Charger: Venom Pro Duo
Works as it should. Will be putting a wire wrap on. Purchased a second one for my dual charger.
Great well built leads, quality connectors, quality soldering and convince of no balance board needed. Two things i would change, make them longer and add some sort of sheathing for them. Would buy again.
Nine reviews, mostly from verified owners, rate this 2S charge/balance adapter with 4mm to 5mm bullet connectors highly, averaging around 4.6 out of 5. Reviewers commonly praise the build quality, soldering and connectors, the convenience of combining the charge and balance leads in one cable without a separate balance board, and the spring-loaded 5mm connectors that are easy to insert and remove. Recurring criticisms include a strain relief that feels weak when unplugging, a request for longer leads and added sheathing, and advice to use 12 gauge or larger leads at high charge currents. One verified owner reported a wire coming loose after a couple of months, which was the only negative rating. One reviewer used a Venom Pro Duo charger, and another noted a dual charger setup.
