Running 2 5V USB battery power packs, Can I use them in parallel
$begingroup$ Welcome to the future! This answer is now six years old, and I suspect it''s no longer accurate. I have a number of 99-watt-hour lithium-ion power banks that output via a pair of standard USB-A receptacles, and they''re all based on the Injoinic IP5306 SoC or one of its variants. When fully charged, these deliver 5.1 V, according to my multimeter

How to build 5v battery pack for ws2812b : r/FastLED
Look online or make your own 3d printed adapters. Then add a Buck converter to supply 5v. I also added a low voltage relay, to automatically turn off if the battery dies. For a small number of LEDs, just cut a USB cord and use a Mophie or Ankor style smartphone or tablet battery pack. (5v) Try to avoid drawing more than 2 amps.

e-scooter external battery in parallel: how bad is it?
Now the 29.5V pack try to charge the 25V pack, the bad cell would discharge even more. Eg3. Temperature protection turns off one pack but not the other. I have the charger shown in the pic hooked up in parallel with my battery and d1 and want to make sure I''m not going to have an 18650 combust or something from overdrawing the battery.
Lithium Battery Management System
As I will have 4 batteries connected in parallel as a battery pack. I will have a total of 11 battery packs connected in series. As I am using lithium ion battery, I will not want to over-charge or over-discharge it. Thus, I need to
tp4056 Series Input power, parallel output (to battery)
The battery pack is a 10s10p 18650, total 36volts 25Ah. So I need to charge the battery and wanted to see if the TP4056 can be used. I was thinking to use 2 or 3 in parallel to charge each 10P battery cell. From my research this is ok as long as the 10P battery cells are not connected to each other which is not my case as I have 10S of this 10P

Lithium Battery Pack
Generally speaking, it''s irrelevant how many cells you put in parallel in each cell group, as long as all the groups have the same number of cells at similar capacities (i.e. you do not want to put one parallel group of 3 cells in series
How should I connect multiple Lithium Polymer battery packs in
You could use a boost converter with a 4.5V source, or you could use a 6V battery with a buck converter, or you could use a linear regulator such as the LM7805 for a
Series and Parallel Configuration of
The Lithium-ion battery pack is the combination of series and parallel connections of the cell. In this blog we are talking about batteries in series vs parallel of Lithium Battery. By configuring
Series or parallel lithium cells for 5v portable power supply?
The most common configuration is a single cell or multiple cells in parallel, for several reasons:-Cost: A single cell only needs a simple linear charging circuit to convert from 5V to 3.7~4.2V, but a higher voltage pack needs a voltage booster to charge it and another switching regulator to drop the voltage down to 5V during discharge. Switching converters need more
Connecting batteries in parallel – BatteryGuy
This means a 1.5 volt battery from brand X could actually be 1.6 volts, while a 1.5 volt battery from brand Y could be 1.55 volts. If these were connected in parallel, you are unlikely to see fireworks, but would experience other issues.
How To Wire Lithium Batteries In Parallel Increase
Why Wire Lithium Batteries In Parallel? Battery cells are wired in parallel to increase their capacity and increase the amount of current that they can handle. Most inverters will stop working at around the 10.5-volt mark,

How should I connect multiple Lithium Polymer battery packs in parallel?
I have an application for which I need a relatively high amount of current @5V. I was thinking of connecting four external USB battery packs like these in parallel, as they output a nice regulated 5V and are easy to charge. But I know lithium chemistries are sensitive souls and having "unbalanced" cells connected together is a no-no.
