Common Charging Settings

I bought a very good charger on Amazon. It being super versatile, I needed to research the best settings for it for our various batteries. We'll grow this data table as our battery collection grows.

Stated Nominal Voltage

Max Charge Voltage Minimum Discharge Voltage Cells Capacity Charge Voltage Charge Amps Max  Discharge Rate Notes
LiPo 12V 12.6V 9.6V 3S 15000mAh 12.6V 2A 1-2 Amps Bought probably around 2014.  Using 2A as charge rate since the factory says 1-2Amps discharge rate.  However, this is very low.  Other LiPos charge at 1C, so it should be able to take a lot more amps for charging.  This battery is great for powering our battery charger to charge other batteries or provide power when camping.
LiPo 14.8V 16.8V 12.8V 4S 3300mAh 16.8V  3.3A(1C) 198A - 60C Awesome for Raspberry Pi projects.  3Hrs runtime
LiPo 11.1V 12.6V 9.6V 3S 2200mAh 12.6V 2.2A(1C) 66A - 30C The size of this is difficult to fit in Airsoft guns.  Good for raspberry pi projects.
LiPo 3.7V 4.2V 3.2V 1S 2500mAh 4.2V 2.5A(1C) 2.5A (1C) The product didn't list its C rating.  So, I'm assuming it is the normal 1C discharge rate.  Good for microController projects, but not Raspberry Pi due to insufficient discharge rating.
NiMh 8.4V 9.8V 7V 7 3000mAh 9.8V 0.4A 30A (10C) Bought 8/2020.  I found these specs by researching NiMh discharge rates.  For NiMh, .1C seems to be the consensus for normal charging with .3C being fast charge.  Opened and modified, it makes a great airsoft battery that will last for all afternoon.
NiMh 8.4V 9.8V 7V 7 1600mAh 9.8V .16A 16A (10C) Decent air soft battery designed to fit well in the stock of a rifle.

BATTERY CHARGING BASICS

Type Nominal Cell Voltage Cell Minimum Allowed Voltage Cell Charge Voltage Charge Rate  Notes
LiPo/Lithium Ion 3.7V 3.0V 4.2V 1C (typically = capacity/1000 mA/A) Never Parallel Charge
NiMH/NiCd 1.2V 1.0V 1.4V .1C (.3C fast charge) If parallel charging, multiply charge rate by number of batteries being charged.  1C charging can be done if attended and temperature is monitored.
