    Hiya. My charger is a version 2 type not version III and therefore doesn't have the HV setting and I do check it is on Lipo. Next time I charge the battery I will take note of everyone's input. Thanks D

    As Dave said, check with another volt meter, (preferably a multi meter) If you can find one, The GT Power watt meter is the best tool you can have. It checks Amps, balances (shows individual cells while balancing or using as a volt meter in line etc. Hard to find but by far the most useful tool for batteries. Does LiPos , LiFe, and LiLo. Also does temp. You have to solder your own plugs on. This place may still have them, buy one while you can if they do

    Thanks for all your advice but I'm still wondering why when the charger says 100% full it is 14.1 volts and not 12.6volts. I only charge at 1.5 amps for probably about 50 mins. There doesn't seem to be a lot of capacity between 12.6 and 11.1v. I have attached photos of the device I use to check the voltages and also the discharge light assembly I have made. Perhaps in future have to charge to about 80% capacity. What do you think please?

    Just an additional comment re your charger. It has a setting for Hv LiPos which will charge that Hv type of battery to 4.35v. In your case you need to select the LiPo option for 4.2 v max. Also make sure 3 cells are selected. What instrument gave you a voltage of 14.1volts? If it was ther charger it could be faulty. A check with another voltmeter should confirm this. If it is faulty the max charging current might be faulty also. If you need to change I use a Giant Power Intelligent Balance Charger G6AC.

    Sorry to have confused. I was referring to the min discharge voltage. Modern higher capacity batteries now recommend a min discharge of 3.5v per cell. Earlier lower capacity batteries recommended 3v per cell. I use 3.5v as my cut off voltage to preserve the life of my batteries. Suitable ESC's have this as a default setting but are also adjustable to other cut-off voltages. The ESC doesn't cut off completely it just limits the current draw to a sfe low level to allow you to return the model to shore.

    That charger is quite suitable for your purpose providing you use the main connector and the smaller white balace charge lead.

    Thank you for all your very useful information. I've attached photos of my charger. I've just checked the voltages whilst in storage and they are 3.7, 3.7 and 3.6. I've also double checked my bulb that I use for discharging. I think it is probably indicator an bulb as it is a 12volt 16w bulb. What charger do you recommend it you think mine is unsuitable. When I was looking for a charger I was informed that a well known trusted charger had been copied and wasn't safe so I stayed away from that make - just in case I got an imitation one.
