I purchased two fingertech-viper-combat-robots. Product Code: RB-Ftr-47 and think I have ruined the batteries. I get a battery connection error when I try and charge them. Can you explain how to program the charger? I think I may have charged them with too much amps (1 1/2 amps)
Hello @Map509
I gave a look at the user manual and it says:
An important note about lithium polymer (lipoly) batteries!
Lipoly batteries have an enormous energy density which makes them fantastic for this sport - where a lighter battery can mean stronger armor or weapons. But this battery chemistry must be treated properly or could become dangerous.If a lipoly pack is discharged below 3.3V per cell (6.6V for a 2S pack) then they will not be safe to recharge. If your robot starts to slow down, it needs to be recharged! If a pack is ever damaged or seems puffed up, do not try to charge it. Replace the pack and recycle the old one.
The included Rhino 7.4V 360mAh pack can be charged at maximum 0.8A. (This is set on the charger.)
So, as you said, 1 1/2 A was way too much for the batteries. If you need a replacement I also found this info in the manual:
Lithium Polymer Batteries
Your kit comes with a 2-cell (2S, or 7.4V) lipoly battery. For more power and speed, it can be upgraded to a 3-cell (3S, or 11.1V) pack. If you are adding a servo or other electronics, make sure they can handle the higher voltage! (Most servos cannot.)
Finally, you can find some battery options here
So this is the one I need?
Reading the How Do I Choose a Battery? guide I would say that you can use that battery.
But I’m no battery expert so I would prefer if someone else would assure you if that one is compatible.
