They can be swapped so they are not paired just the UART communication is missing. As long as we can fake that it could also work out.

I thought evolve ran liions in their boards? Something like prismatic cells.
Sorry for off topic
Yeah theyâre prismatic pouchesâŚ
Thatâs good, itâs not as problematic as it could be then. Looks like either spoofing the UART or modifying the firmware should work fine. Just needs someone with a working BMS to investigate 
it looks like evolve uk tech team is one person, maybe you should just go in there directly. i see alot of spare parts 
Itâs not an âunlock handshakeâ itâs constantly transmitting the current battery level, which gets sent on to the remote. The problem comes in with their feature of automatically switching to ECO mode at 5% battery⌠if this UART connection is not made, itâs sending 0% battery life to be displayed on the remote, which causes the remote to automatically switch the ESC into ECO mode. Itâs entirely possible the offending lines of code are actually in the remote, but fixing it here would still mean you had a broken board battery gauge. So really itâs the sending of current voltage via UART from BMS to ESC that needs to be emulated
So you can put ANY bms on it you want, and it will work â IN ECO MODE the whole time, which is 25% max power

Replace Evolves ESC with a couple VESCs and just get your own remote. Problem solved

That is the best solutionâŚ
Seems like it wasnât an intentional effort to prevent fitting a different BMS then. I would either make something to send voltage data to the ESC as normal or change the firmware so that the eco mode settings are the same as the normal settings in this case. Hopefully somebody sorts some solution
I suspect I could make a receiver for the original remote, but I donât have one to hand so canât say for sure. I assume they are 2.4GHz? I personally thought the travel on the throttle is too short on those remotes to be comfortable when I tried one, so maybe a replacement is an advantage.
Yesďźthe BMS are paired with ESCďźDonât swap themďźI tried to swap my boosted v1 controller to another boosted v1 batteryďźdidnât workďźthen I swaped backďźit wonât work anymoreďźboosted firmware are highly encrypted. IDK why evolve has to copycat that too since their software&controller are not that good to be copiedďźmaybe they should put more attention to developing their software instead of encrypt it.
I really donât think the BMS is paired with anything or encrypted to the ESC etc. Iâve made up 18650 packs before, using spare BMSâ and installed in to a BGT and all worked perfectly.
It literally is just a handshake between the ESC and BMS. It might even be the case that you could connect one or more of the wires together to fool itâŚ
The ESC is not paired to the BMS, because Iâve changed it. To re-pair the remote to any Evole GT ESC in range, hold the left remote button downâŚ
@mwkeefer Had posted on another topic about a module he had working to trick the esc. Any input?

Duh, the force ECO mode upon 5% left battery is dumb as shit.
Riders need safety features foolproof and honest after sale services, not babysitting.
BTW Evolve canât take direct actions against any individual modifying a board apart from breaking warranty and Evolveâs liability.
Once sold the customer buys all the ownership rights on it without reserve, apart from patent protections (which doesnât concern us here) nothing can be done.
A clause forcing customer to keep coming back to the manufacturer with different consequences than warranty breaking or Evolveâs refusal to further take in charge the product for repair is anyway illegal and will easily be canceled if it goes in a court.
Thatâs basic property rights, how come they even think about threatening you.
How about they eat shit?

I know, exactly what I said. You buy the board itâs yours to do with what you wish. You wanna strap a rocket to it, no one can stop youâŚ
How much kv is that? Will my vesc fry?
I believe 20000kv!
Over 9000 !!
