MEANINGS OF DISCHARGE RATES, CHARGE RATES AND CAPACITY:

 

DISCHARGE RATES

 

5C – capable of discharge 5x it’s rated capacity

(1.2Ah x 5C = 6 Amps)

 

10C – capable of discharge 10x it’s rated capacity

(2Ah x 10C=20 Amps)

 

15C – capable of discharge 15x it’s rated capacity

(1Ah x 15C = 15 Amps)

 

 

CHARGE RATES

 

All Li-Polymer cells sold by TrueRC should be charged at 1C rate or less.

 

For example:

 

1200mAh pack should be charged at Maximum 1.2 Amp

(1.2Ah x 1C = 1.2 Amp)

 

If your charger does not have the specific charge rate ALWAYS use the lower one

 

For Example:

Your charger setting allows you to charge at 0.5A, 1A or 1.5A.

You MUST charge your 1200mAh pack at 1A

 

 

CAPACITY

 

1Ah = 1000mAh

2Ah = 2000mAh

4Ah = 4000mAh

2.1Ah = 2100mAh

1.5Ah = 1500mAh

1.2Ah = 1200mAh

0.7Ah = 700mAh

 

CHARGING CELLS AND PACKS

 

Safety Data Sheet – READ FIRST

 

Always monitor your charge.

 

Li-Polymer cells require a Li-Polymer charger. You MUST use a charger that was specifically designed for that purpose.

 

Each cell is rated at 3.7V - This is a NOMINAL Voltage

Each cell can be charged up to 4.2V - This is MAX Voltage.

Charging over 4.2V per cell will cause damage to battery, persons or property.

 

A 2 cell 7.4V battery pack will charge to 8.4V MAX

A 3 cell 11.1V battery pack will charge to 12.6V MAX

 

Battery packs with cells out of balance (Voltage), arranged incorrectly or severely damaged will cause a FALSE cell count. 

 

ALWAYS inspect & check Voltage of your pack & individual cells (when possible) right before charging.

This MUST be done with all Manual/Jumper Chargers as they will do what you tell them.

 

A fully discharged pack (down to 3V per cell) should read

 

2S 6V or higher

Charge as 2 cell

3S 9V or higher

Charge as 3 cell

4S 12V or higher

Charge as 4 cell

 

If you have a pack that is built in parallel

For Example:

 

2S2P 7.4V 2400mAh ( built from 4 x 1200 cells ) you ALWAYS charge as a 2 Cell pack, but you can charge it at a higher rate of 2.6 Amps (2.6Ah x 1C = 2.6Amps)

 

After charging is completed the Voltage may not be Maxed out. This is because some chargers will limit the charge to less than 4.2V per cell.

Your pack may be within these limits:

 

2S fully charged voltage (8.32V to 8.40V)

3S fully charged voltage(12.48V to 12.60V)

4S fully charged voltage(16.64V to 16.8V)

 

2S – 7.4V   Nominal – 8.4V Max

3S – 11.1V Nominal – 12.6V Max

4S – 14.8V Nominal – 16.8V Max

5S – 18.5V Nominal – 21V Max

6S – 22.2V (also available as a custom pack) Nominal – 25.2V Max

 

DISCHARGING

 

Our cells are rated by manufacturer to discharge to Maximum of 2.75V per cell under 0.2C load. Discharging to that level at higher rates will shorten the life of the battery or damage it completely as most brushless ESC’s (electronic speed controllers) don’t have an accurate LVC (low voltage cut-off).

 

A common LVC point is 2.8V–3.0V per cell. This is a SAFE setting for higher discharge rates. Some brushless ESC’s are programmable and can be set up to either point & others are factory pre-set. If you discharge to 2.8V per cell the battery should “rebound” to around 3.15V or more after rest.

 

Careful when using older brushed ESC’s – They are meant to be used with NiCd and NiMH and the LVC is way below that of a Li-polymer.

You can still use them but you have to monitor your run times and watch for power loss.
