HI , I’m wondering if a kit of lithium battery 14.4 volts , 5600 m.a.h. would fit on a 180 acorn wich was previously using nic/cad batterys. The watt/power from the lithium battery is higher but would it be damaging the control board by using 14,4 volts instead of around 13 volts . I already tried a test for 2 weeks and didn’t seem to damaged anything . Acorn start to manufactured liftchair that are using lithium battery as i could see on the web ,How do we recognize the new one from the oldest .
The new one that uses lithium bats are the 565 controller pcb ones
