LiPo Rider v1.0 (current?) power

Help & Support Robot Parts

On the latest LiPo Rider charging/power board there are four (4) places for resistors, R7. R8, R9, &
R10. I assume these are for changing the charging output current. I’ve looked for references of what they are, yet have found nothing. Does someone have this information, what value for what change?

Thanks,
Barry

Hi,

I have reviewed this information previously, I was not able to determine from it, what resistors added would induce what changes in performance. Just a note, the current board shipping is the v1.0, the references available are v.9 and v1.2, I don’t know if there’s conflicting changes, or not - but that’s another matter.

Hi Coleman,

Actually, the board has (4) open connections for R7, R8, R9 R10. There are NO resistors there. From my previous experience with these type of boards, you add a specific value resistor to a position to increase the “current” output for charging. For example, “open” may be 100mA, with the addition of a resistor you can reach the maximum of 400mA. But you need to know the value and position. I did review data from the company and found nothing more. I guess I’ll have to shoot them an email.

best regards,
Barry

Hi,

You can see the resistors mentioned in the schematic (bottom right). As for their function, not sure yet.

Hi Barry,

Are you hoping to change the resistors to alter the charging voltage? If so, it’s certainly a design issue and you may want to contact the manufacturer directly to get their input.

Sincerely,
