About this part

The S100 Smart USB-C Charger makes battery charging the easiest it has ever been. Its Auto Charge feature recognizes your Smart battery's parameters, such as chemistry type and charge rate, and automatically begins safe, correct charging when the charge lead is connected. Balancing Smart batteries is just as simple. The S100 charger will balance your Smart G2 packs through the same single IC connection used for charging. No separate, confusing balance leads are required. Powered by an included USB-C cable, the S100 is a convenient charging solution for those new to RC. All you need is a common USB-C power adapter, and you're ready to go.


Features:
  • Advanced, user-friendly Smart charging technology that fits into any hobby budget
  • Meter display shows available wattage on startup, making it easy to know how much power your USB power supply can deliver
  • Delivers up to 100W of charging power with appropriately rated power supply and USB-C cable
  • Charges AND balances Smart G2 batteries with one simple IC3 or IC5 connection — no separate balance lead needed
  • Auto Charge recognizes Smart battery charging parameters and begins safe, accurate charging automatically when connected
  • Charges virtually any RC LiPo battery (use Smart batteries to benefit from all charger features)
  • Smart software tracks and stores numerous smart battery data
  • Includes IC3 and IC5 charging output ports — eliminating the need for a separate IC3 or IC5 adapter to charge Spektrum Smart batteries

Thomas GaskinVerified owneron Spektrum RC S100 DC/USB 4S LiPo Smart Charger

this little charger is awesome, i did have to buy an ic2 to ic3 to charge my mini t and mini b batteries, but i had to buy something because the charger that came with the mini b stopped working 3 charges in??? if you need to replace the charger for your mini b, this is it, it charges many different batteries, this is the adaptor you will need to charge ic2 batteries Spektrum RC 6" IC3 Battery to IC2 Device SMART Battery Adapter Cable, SPMXCA320

Brice WiresVerified owneron Spektrum RC S100 DC/USB 4S LiPo Smart Charger

Great charger. Was sent as a replacement for the granite groms charger not working. Charges quickly and shows a good bit of information while charging. Use with a 65w type c laptop charger to get full charging potential.

i have it works good just make sure you a type c cord that can put some amps to it

What reviewers say

Reviewers largely find the charger works well once set up: it charges quickly, shows useful status information during charging, and is simple to use with a USB-C power source, with one reviewer noting a 65W laptop charger gives full charging performance. Several note that a USB-C cable or adapter capable of supplying enough current is needed. One reviewer reports the unit burned out after about ten charges with smoke and no battery attached, a serious failure that is not echoed elsewhere. One reviewer mentions needing a separate adapter to charge IC2 batteries and that the charger replaced a faulty unit from another brand. The sample is small, so the overall picture is limited.

  • + Charges quickly
  • + Shows useful information while charging
  • + Simple plug-in operation
  • + Works well with a 65W USB-C charger
  • − Requires a USB-C cable that can supply sufficient current
  • − Reported burnout after about 10 charges
  • − Separate adapter needed for IC2 batteries
