amps

Hi I have a 18650 8.4v 2s2p battery pack. It is fully charged at puts out 8.4v but it does not appear to give enough amps to light the leds. Could a battery fail in that way? Battery pack still rather new. Leds are in working order. Was working last winter but for some reason not this one. Any...

Hi, Short discharge question ;). If I place cells in parallel, I increase the Ah but do I also increase the maximum discharge current? For example, 4x4.2V 3000mA 10A (continuous discharge current) cells in parallel. That makes 4.2V 12000mA 40A battery or a 4.2V 12000mA 10A battery?

Could really use some helpful tips right now. I built a 52v battery and the thing is overheating so bad, to the point that the hot glue actually melted and it was too hot to touch. My first thought is that the amps are maybe too high for the controller, but I'm not sure. I used samsung 30q...

Hi, I have a question about continous amps output. For example, some batteries output about 5amps continous and with 6 in parallel it makes sense it has a 30A continous BMS. What if the batteries had 20A continous with 6 in parallel. This would be 120A continous. Could I use a 30A BMS or MUST...
