I’ve got a Liftboard single motor that I’m trying to get back running. Thanks to @Plurf I’ve got a remote on the way but I want to check other aspects of the board.
I’ve been able to power on the board but not sure what the LED activity means. If I just power it up, the light slowly blinks red. If I hold the button for 5 sec, like you do for pairing, it goes from slow blinking to rapid blinking red.
I was concerned it may be the battery so I put it on the charger. It doesn’t ever show that it completes charging. When I check the voltage at the charging port, I get 1.1V. This doesn’t make sense as it shouldn’t even be able to power the LED at the voltage level.
How bright are the LEDs? Many LEDs can run with lower voltages but usually they ends up being very dim as a result.
If you can, I’d measure the voltage directly from the battery or at least from the battery’s output to see what voltage it really is at. (battery output being what is feed to the controller). If you measure from the output that goes to the controller then you’ll probably get the voltage out of the BMS
This sounds like what some escs do when they’re on but have no remote connected. Once the paired remote is on then the LED changes to be constantly on.
yeah, even better you can check each parallel group from the bms pigtail, that should give you a good indication at the battery state and what the issue is
If I remembre the liftboard pack is not heatshrinked, at least not the bms,
the pgroups are hold in place by rigid abs holders and the bms is out of the pack close to the esc
but the metal tube enclosure is a bitch to open, I don’t exactly remember
EDIT: I checked and shrink there is, totaly forgot it
wrong topic ?
I’d say best chance is any 12s psu + a smart bms (llt is fine quite good and affordable)
I don’t know of any of the shelf 12s balance charger at a decent pricepoint
