Bantam CheckMaster II faulty or not?

[RotorSmiths]

Anyone with a CheckMaster II seen this?

Brand new unit - trickle charged for 24 hours, switch on and everything appears to work OK, BUT go to the temp/internal battery screen and it reads 5.3V 110%, straight off charge it was about 5.7V 120%. Is this OK?

The manual says it has a 4.8V 800mAh NiMH battery.

Is the unit faulty or is there a calibration on the battery that I need to do?

Also the manual says you can charge it "with any rapid charger capable of charging a 4 cell NiMH battery at about 1.0A of charging current". 1 Amp, isn't that too high?

Any help appreciated - I need to return to my dealer if it is faulty and get it swapped out.

Anyone have comments please?

NiMh/Nicad voltage is higher than it's rated voltage when fully charged
Nothing wrong with your batteries there

Some NiMh/Nicads are fast chargable i.e. 1 hour charge
The 1 amp charge rate would be fast charge
The battery would get quite warm if not hot
Trickle charge for your battery would be 0.1amp(100ma) for 8/9 hours or 50ma for 16/18 hours

Thanks for the reassurance. Sounds like it is probably all OK then, the tacho and servo control functions all appear to be fine, it just seemed a bit weird that they calibrated the power meter to 120%.
