When I try to charge my 5500 mah 3 cell lipo battery the B6 limits me to only 5000 mah, no higher. Is this normal or can I manually raised the mah limit somewhere in the menus?

thanks,

In the menus, go to User Set Program. A couple options in there's Capacity Cut Off. If you can raise it go for it, otherwise just turn it off.

I had tried that. Tried raising the limit and shutting it off. Then tried again charging the 5500 battery. Still will only let me take it up to 5000.

thanks,

your charger has a limit of 5amps.
this is 5000mAh.

This is why...to answer your question..its normal for that model charger.

In fact the B6 range of chargers are 5A or 50W .. whichever is reached first. The display may say 5000mA ... but in fact actual charge will be limited to 50W / Volts max.

I think there's some confusion creeping into this thread that perhaps the OP can clarify...

From posts #1 and #3, it sounds as though the OP's charger is terminating charge at 5000mAh of replaced capacity, prior to the battery attaining full charge. The OP indicated that he attempted to raise the capacity cutoff and disable it altogether, both of which yielded unsatisfactory results.

If my interpretation of his description of the problem and attempted resolution is correct, the charger is likely faulty.

I may be wrong - but I read it as he cannot raise charge CURRENT / RATE above 5000mA .... the fact he says mAh is as I read it an error of units.

This is not first post for this very matter ... quite a few other threads have been written in past about the 6 range of chargers not giving out more than 50W ...

But if it is capacity cut-off - then the B6 chargers appear to have a max cut-off of 5000mAh ... just checked my manual and is actually doesn't say what max is - but shows 5000 in diagrams.

Can the OP please clarify ...

is that 5500 charge rate or capacity ?

Capacity

Meaning the charger stops charging when capacity reaches 5000mAh and your lipolys are undercharged at termination? Or you cannot set capacity above 5000mAh prior to initiating a charge cycle?

He's trying to set the charger to go above 5000mAH (5amps)
Its not designed to go above 5amps, or 50watts

Its a simple case of the OP not being aware of the specifications of his charger.

He would need the B8 charger if he wanted to set his charger above 5 amps.

I agree that you and Nigel are likely 100% correct.

Now ... I am a little confused.

If OP is trying to replace 5500 mAh into a 5500 mAh pack - then that is impossible if pack is still in useable condition. Why ?

It would mean that OP had dragged pack down to ZERO discharging its entire capacity. No LiPo will tolerate that ... in fact near all rechargeable cells would give up on that. Hit zero and your charger will fail to resurrect that LiPo.

Safe limit to discharge is about 80% or less ... so in fact OP should be looking to replace about 4400 mAh MAXIMUM to a 5500 mAh pack.

That clears up the CAPACITY side ...

If it's charge RATE - then as said - the 6 range of chargers only provide a maximum of 50W overall .... but 6's also have a maximum current rating of 5A ... 5000mA.

Solentlife,

OP has a 5500mAh pack.
conventional teaching says to set the charger to 5500mAh

His charger only goes to 5000mAh

He's wondering where/how to do this with his charger, not fully understanding about the specifications of his charger.

OP, you need a better charger such as the B8.

YOU CAN charge your 5500mAH pack even if your charger can only be set to 5000mah.
It just means that you can't charge your pack at 1C or higher and it will take just a bit longer to reach max charge.

Your charger's circuitry will not stop the charge at 5000mAH...it will stop the charge when it senses the voltage holds at 4.2v per cell
