About this part

The ProTek RC 1S USB LiPo Charger was developed specifically for ProTek RC PTK-5197 and PTK-5550 1S LiPo transmitter batteries. Have you found that your charger is not fully peaking your transmitter packs? Some high end chargers struggle to put a full charge on these batteries due to the way the charger measures resistance, and no matter what you do, they will not peak at full capacity. This small and affordable option solves that problem. With a fixed 1 amp charge rate, LED charge indicator, and easy USB power access, this easy to use charger will ensure your JR connector equipped 1S transmitter batteries get a full charge each and every time.

Problem solver. Makes it dead simple to charge the battery pack for my sanwa mt-5.

Probably the best charger invention of all time! Totally saved me when it came to charging the M17 1s battery. Not even my $300 charger could peak this pack. I love it!

Josh BissVerified owneron ProTek RC 1S USB LiPo Charger (1 Amp) (Sanwa M17 & MT44)

Works as advertised, charged my Protek 1s Lipo for my radio in no time. You’ll need a USB charger as this is just the cable.
