In stock, how much does the constant amperage “matter” ? Say if I had a 80a vs 120a. What do you benefit from that. punchier ? more efficient ? I just want to better understand this to help my decision. ]]> Radio and Electronics Fast410 https://www.rctech.net/forum/radio-electronics/1141841-stock-tc-esc-suggestions.html Reading IR with iCharger X8 https://www.rctech.net/forum/radio-electronics/1141830-reading-ir-icharger-x8.html Fri, 22 May 2026 15:18:01 GMT I have been using an iCharger X8 for the last few months of 12th scale GT12, and I run mostly 1S battery packs in this hobby. I have a couple of 2S for a buggy I'm working on for summer, and I just figured out how to check actual IR on the battery, clicking the lever wheel up once the battery is first connected. It works perfectly on the 2S pack, but not at all on the 1S packs, instead putting the LR number where the IR reading is on the 2S packs. I *just* learned what the LR number was (I know, I know) and that it wasn't internal resistance. The instructions for that charger can be great and terrible at the same time, but mostly terrible.

How do I access the IR on a X6 of X8 for a 1-cell battery pack?

Both of mine were an early batch and weigh 273g and 275g respectively. One of my fellow racers received a pack from a more recent batch, and it's significantly heavier, around 295g (he also has one from an earlier batch, which is in the 275 range). This seems rather unusual, and for racers under BRCA or similar rulesets that have a 4% weight tolerance, this would make such a pack illegal for sanctioned racing. Has anyone else noticed such a big discrepancy with their pack weights? ]]> Radio and Electronics gigaplex https://www.rctech.net/forum/radio-electronics/1141771-team-eam-battery-weight-tolerances.html Icharger 308duo temp sensor problem. https://www.rctech.net/forum/radio-electronics/1141722-icharger-308duo-temp-sensor-problem.html Sat, 16 May 2026 15:25:01 GMT Last night I had to show up to the track late so I sent all the gear and my 14year old son to the track with my buddy to get setup before I got there.

Last night I had to show up to the track late so I sent all the gear and my 14year old son to the track with my buddy to get setup before I got there.

When I got there he had a battery on channel 1 and it was showing the unsafe temp error. Tried to run the charge again before I realize he had the 2s balance plugged into the temp sensor instead of the balance port despite the fact he’s done it multiple times previously and I told him to watch for that. Hasn’t caused a problem before but now it’s reading 124deg C with nothing plugged in and it immediately shows the error when you try to run a charge. Has anyone had that happen or know how to recalibrate the temp? Channel 2 is reading and working normally. Apologies if it’s in the manual but I read it again recently and don’t recall seeing that.

thanks for the help. ]]> Radio and Electronics wydopen https://www.rctech.net/forum/radio-electronics/1141722-icharger-308duo-temp-sensor-problem.html Help with Spektrum SR615 + ISXR+ glitching servos https://www.rctech.net/forum/radio-electronics/1141595-help-spektrum-sr615-isxr-glitching-servos.html Fri, 08 May 2026 13:15:00 GMT I have issues with my new SR615 receiver.
