Discharge Resistor Bank 4S

Description

Discharge Resistor Bank 4S

Resistor Bank 4S gives your iCharger DUO a fast, clean way to discharge race packs. Moreover, it pairs well with iCharger 406DUO, 308DUO, and 4010DUO power levels.

Specifically, a 40A cycle can help lower internal resistance for stronger punch. Therefore, you get more consistent power across heats and mains. For proof, you can review our internal resistance test results in our videos here.

In addition, an RC enthusiast designs this discharge bank and builds it in the U.S.A. As a result, you get a tidy, track-ready setup that fits your pit routine.

Why racers choose this resistor bank

First, this add-on helps you condition packs quickly between runs. Next, it saves space because you skip bulky resistor stands. Finally, it keeps your wiring short and organized for safer handling.

• Discharge LiPo packs from 1S to 4S at up to 40A
• Smart fan controller for stable cooling
• Runs cooler thanks to the box enclosure design
• Saves room and time with an all-in-one layout
• Plugs into your iCharger easily for quick setup
• Clean build with short wires for a neat pit table
• Optimizes space with an integrated enclosure

Also, you can pick another version if your class needs it. For example, see the Discharge Resistor Bank 2S or the Discharge Resistor Bank 6S.

Discharge rates and power notes

Notably, discharge current depends on cell count and charger limits. Consequently, you can plan your turnaround time before the next round. In addition, you can compare versions below.

*With Power supply 12V, Maximum 500W on iCharger 406DUO, 700W on iCharger 4010DUO
**With Power supply 24V, Maximum 650W on iCharger 308DUO, 700W on iCharger 406DUO, 1000W on iCharger 4010DUO

Resistor bank features and fitment

Resistor Bank 4S fits iCharger DUO setups with 10awg wire and built-in 4mm bullet plugs. Furthermore, it supports extra discharge mode with iCharger X6 and X8. Therefore, you can discharge or charge at 30A with the iCharger X6/X8 or the 308DUO.

Additionally, if you want background on how resistors dissipate energy as heat, review resistor electrical load basics.

Product dimensions and stand setup

Meanwhile, the enclosure keeps your pit area compact and stable. Next, use the table below to plan your stand and power supply placement.

Version / Size	Width	Depth	Height
Resistor Bank 406/308*	7.6in (194mm)	4.9in (124mm)	4.9in (124mm)
With Charger 406/308*	8.6in (218mm)	4.9in (124mm)	7.0in (178mm)

* Power supply recommended dimension for the stand:
