Hello: Nobody answered my question The whole reason I need to balance my
batteries is that a number of batteries reach 3.6 volts before the others,
who only reach only about 3.3 volts The Orion BMS shuts of the charger and
balances the batteries but, the same problem occurs after the next
recharge . I've discharged the batteries a number of times but, they still
bounce back to about 2.51-2.53 volts . Do they need to ALL be exactly 2.5
volts before recharging?
Hi John,
When the batteries reach anything close to 2.5v, they are effectively
dead -- no useful capacity remains. It doesn't matter whether they're at
2.5v or 2.6v -- they're still DEAD!
I don't recall what current the Orion uses to balance, but I think it is
pretty small (milliamps). It may be that your batteries have aged to the
point where the differences between them are too large to balance with a
small current.
