digital weight machine 4v led acid battery replacement with lithium ion 18650
important note: you cannot replace 4v lead acid battery with 2s lithium ion it will damage your machine always use only 1s 18650 lithium ion battery
LifePo4 is not recommend because single cell voltage is too low or 2s voltage is too high
so similar is only 18650 4.2v 3.7v
battery
thank you
