Li-Ion Batteries
Hi Allen
I use these batteries and apart from the cheap Chinese imports they can give a high current. The drawback is that they are protected internally against overheating and as a result they can (and do) sometimes just stop working until they cool down.
In a heavy current setting such as a tug for tug football or a fast electric this is what happens. if you are using in a more sedate model with low current draw they are fine. Also excellent for rx batteries with a switch mode psu.
They are Lithium technology so do need to be balanced charged with the correct charger, but are more resilient than LiPos but still need to be respected.
Common usage is in a rechargeable electric drill etc.
You can buy battery holders for the cells which will avoid having to solder and makes charging easier
I remember Torchy, just

Li-Ion Batteries
Recently fixed my Son's hand held rechargeable vacuum cleaner and was impressed by the power of the Li-Ion battery. Picked up a bag of 8 x 18650 3.7v 3500 mah batteries and 2 chargers at the Boot Sale this morning. £10 seemed reasonable. I fancy putting two in series in a battery holder to give me 7.4v at 3500 mah. This seems too simple. What am i missing and why are Li-Ion batteries not used more regularly for model boats? I need a battery guy's guidance please. ........and I don't mean Torchy. Younger members may find that reference a little obscure.
