I was wondering, since lipo's go past 3 cells, what modifications need to be made to handle 4 or more cells? If that's not possible without causing a thermo nuclear meltdown, is there an ESC on the market that can handle the additional cells and have the same forward/brake/reverse we need? Thanks!
A few years ago there was an article on modifying the ESC to handle 22 volts. I believe the article has since been removed by the author. There are ESC's out there but they're for planes and are mono-directional. I know they exist but just looking for the way to modify what is out there. I could just stay with 3 cell and call it a day. Just looking for options
Ahhh Ok now I’m picking up what you’re looking for. There is a 6s for Traxxas 1/10 RC but they are brushless and $260ish bucks.
Look for robot supplier websites. Combat robots were using very high voltages long before most other hobby applications, so I would not be surprised if they have reversible ESCs that can handle 6s LiPo or more.
Brushed. Years ago I picked up a large stash of motors at a swap meet. The guy came over and said "10 dollars buys my table." Obviously I took it!!! I'm just looking for options as some of them are high voltage motors
I followed the modification instructions that were posted a few years ago (basically removing one of the chips and the positive wire), but all it got me was a dead ESC - it's possible I made a mistake but I would recommend just finding an ESC that is rated for the desired voltage. A few of us have used this ESC, which allows up to 24V. When using it along with a brushed pump, we've seen interference issues ranging from occasional glitches all the way to the ESC not functioning with the pump running, and standard interference reduction techniques were ineffective. They work great otherwise (for convoy or using brushless pump) https://www.revrobotics.com/rev-11-1200/ The hobbywing 880 can handle up to 4S LiPo https://www.hobbywing.com/goods.php?id=650&filter_attr=5426.5599.0.0.0.0.0.0.0.0
Might be more bulky that what you want, but I've been using DC-DC voltage converters in my boats and they work great. I put two 7.2V stick packs together yielding 14.4V, and then convert to 12V to run pumps and 6V to run everything else. Something like this might work: View: https://www.amazon.com/uxcell-Converter-Regulator-Waterproof-Transformer/dp/B01CUA4KK8/ref=sr_1_5?dchild=1&keywords=voltage+converter+12v+6v&qid=1634575269&sr=8-5
