There aren't any special settings for a 30A charge rate, simply set it to 30A and hit start ... if that's not working and you are sure your power supply and battery are good then you probably have a bad charger, maybe try re-flashing the software but if that doesn't help send it back for replacement.

Default Working

well with the help from RLpowersupplies and Ron Schuur I got it working. You can not charge with the resistor banks connected in the circuit.

no do not charge with the resistor banks

Well duh, can't charge a resistor

Default I learned

I didnt think about it until after it was brought to my attention. lesson learned.
Has anybody discharged a 1s at 20 or 30 amps yet?

Thanks Chris

So make a high power switch over the resistor bank so you can switch between charge and discharge w/o reconnecting wires.

Default Dicharging

well lipo discharging with resistors is great but my R1 LHIV 2 s batteries will not discharge past 4.5 amps. What gives?

Default Discharge

I did check my resistors they are fine. They work on lipos but not LIHV. Setting for LIHV discharge is at 20 amps what other setting should I look for? Thanks for your help and suggestions. I know enough about electronics to be dangerous.

Thanks Chris

Default Resistors

each resistor is 1ohm and 100 watts
how many resistors to do 20ohms and how many to do 30 ohms ?



how many and which type to do 1s?

thanks Chris

Great little charger but it looks like I'm screwed trying to get t to discharge at 30A for a 1s lipo for 12th scale

Default 1s discharging

yea Discharging a 1s is not working right. 17.5 amps is all I can get and with the correct resistors it just defaults to 4.0amps

no need to discharge at that rate for 1s

1s and 2s lipos will also be different.

discharge at 30 amp = xxx ohms
discharge at 20 amp = xyz ohms
discharge at 10 amp = abc ohms
From the manual:


External capacity resistances setting:
R = Vbat / Iset;
P = Vbat * Iset;
R: The value of the external capacity resistance
P: Rating capacity of the external capacity resistance
Iset: Discharge current
Vbat: Battery voltage
For example: discharge a pack of 20V lithium battery at 7A

R = 20V / 7A = 2.85Ω
P = 20V X 7A = 140W
So basically, the voltage of a pack devided bt the wanted discharge current.
So when after racing the voltage per cell is about 4V and you want 20A discharge

R = 4v / 20A = 0.2 Ohm
The wasted power : = 4v x 20A = 80watt

Most resistors come with a so called E12 number = 12 values between 1 to10, 12 values between 10 to 100 etc. but also 0.1 to 1
http://www.resistorguide.com/resistor-values/

Taking 5 parallelk resistors of 1 ohm with 100 watt each is overkill, in the above case 25 watt resisters would be fine.

When using equal resistors in a parallel connection the total resistance is one resistor devided by the amount of resistors.So to get 0.2 ohm you need 5 of 1 ohm, 4 of 0.82 ohm or 2 of 0.39 ohm. The total power wil be devided equally ove all resistors, so with 80 watt an5 5 resistors the power is 80/5 = 16 watt -> some over dimension is wanted so 20 or mere is better. When using 100 watt resistors probably no cooling is needed but still a better option when used.
