Just for future reference for anyone with a similar question relating to swapping lead acid to lithium with lvc. A good lithium pack CAN be taken down all the way but it's not recommended but CAN be done without damage So with a 60v system the lvc on the controller will cut you out at 48v...

Thanks a lot btw so I have looked into it I'm going for a 2000w 60v hub motor for the front wheel which will allow all 3 wheels to be driven for if on mud or any non solid surface and will give me the speed id like What I have done aswell I've went for 21 18650 2900mah cells and a BMS for...

So the plan was to have 1000w as it's ok for what a mobility scooter should be as these are sold new with that spec Then I was wanting a seperate front motor on a seperate X5 battery's for the front wheel that will be on a seperate key that won't be carried while on public roads that would be...

Sorry as I say Im learning but I was maybe not clear the current battery's are out of the bike as there totally dead tried them on the pulse charger etc there unrecoverable......there the old lead acid or gel type I know they go down to 48v only to protect them as that type can't be discharged...

Thanks for the input guys if someone could tell me what resistor does the low voltage control I would appreciate it If you need other pics please ask also I would be open to a better controller that would be easier to put a lower low voltage control on as I plan on getting a 3000w motor...

There agm 12v 20ah the now mate X5 so 60 volts They did when nearly new go for miles no issue before it got the 48v so there definately buggered! The new ones are 12v 25ah lithium https://a.aliexpress.com/_mOhKGm8 So initially I'm gonna have the 5 like now but as I say there gonna be...

Here's some pics

So I'm going for these https://a.aliexpress.com/_mst6c3I So I'll need to get the lvc taken down

Thanks a lot for all the information it's great to know about the low voltage control so I'm reading I can replace a resistor with a 100k pot to adjust the low voltage control for if I'm replacing my battery's with lithium and a new charger As am I correct in saying lithium can go down to 20%...

Hi So I have a 3 wheel trike it was initially a green power bz500 like in the link here https://www.mobilitypower.co.uk/product/bz500/ So we bought it but everything was blown on it even though it was only 7 months old! So literally all that was used was the frame and the X5 12v 20ah...
