Can someone please help me to find a battery similar size to a 9v battery and with 9v but a higher current than a 9v battery. Around the current value of a 6v lantern battery. I have started looking but so far I’ve had no real luck.
Putting 2 9v batteries in series only increases the voltage to 18v but does not change the current.
And having a 6v or 2 6v (12v) lantern batteries is way too big to fit into a small pocket
I am therefore stuck on how to power the lights. I was able to make my circuit work but it required 2 6v lantern batteries in series as it supplied a large enough v and a high current, but the size I need is around 2 9v batteries.
Is there another battery that I could potentially use? Maybe rechargeable? I am going through batteries really quickly as the lights just draw way too much current so the rechargeable option may be best.
I have looked at:
PHOTO/ELEC 6V LITHIUM BATTERY DL223AB - 1400
ZNTER S19 9V 400mAh USB Rechargeable 9V Lipo Battery
Ultra Lithium 245 Battery - 1470
But then I also saw:
Which are designed for remote control toys? But could this work?
But I’m not sure.
Background: I need to power 3 8x8 RGB Matrix (Not all at the same time), I have a 5v Regulator to supply a constant voltage (7805). I have tried 9v batteries but they drop in voltage really quickly.
I have learnt that placing 2 9v batteries in series only increases the v to 18v but the current stays the same.
If you can help can you please direct me in a direction where I can get the battery and if it is rechargeable, somewhere to get the charger from too.
