| Hi NBHeli,
I have included part of the TP205 balancer manual at the end of this post. The TP205 balancer will probably be in the "C" mode below with the yellow status LED flashing, and the beeps may drive you nuts a bit. It is normal however with our pack after a deep discharge that the cell voltage is differ by more than 0.2V. Simply charge as usual and the voltage should balance out shortly. If this voltage difference and the beeping really bothers you, set your cut-off at 3.2V per cell and the voltage should be quite even among the cells.
Thanks.
Barry
TP205 manual excerpt:
A: Imbalance under 0.03V: yellow status LED “on”, red LED(s) “on” for 5 seconds. Proceed with normal charging If yellow status LED “ flashes”, pack average voltage is below 3.6V
B: Imbalance 0.03 to 0.2V: yellow status LED”off”, red LED(s) flash for 5 seconds Charge at 0.3A to balance the pack or proceed carefully with 0.5C charge. If yellow status LED ”flashes”, pack average voltage is below 3.6V Proceed with normal charging
C: Imbalance over 0.2V: yellow status LED “off”, red LED(s) flash for 60 seconds. Battery may require repair (Keep battery plug into the balancer for auto self balance, do not charge battery until bleeding/balancing stop). If imbalance remain >0.2V, balancer continues beeping every minute for 10 seconds.
If yellow status LED begins flashing, pack average voltage has dropped to below 3.6V. You may charge the battery at 0.3A and monitor charging for one hour, if the beeping stop but bleeding continue, unplug the charger and balancer to retest the pack with balancer. If beeping continue, you need professional help.
