5S, 5100mAh, HV 35C Lipo Battery, Ultra Light (Power Unlimited)

Power Unlimited 5S 5100 HV Lipo Battery Pack

New Pack - Less Weight

High Voltage cells can be charged to a maximum of 4.35 volts per cell.

Normal voltage cells are charged to 4.2 volts per cell.

Used by many top fliers at the USA Nationals they have a proven track record.

Amazing weight to performance ratio.Super Lightweight. 518 grams (18.25 oz.)

Next-generation Power Unlimited HV Lipo 5S 5100 mAh 35C, 19 volts at HV charge

In theory, charging an HV pack at 4.2 volts will yield a 4500 mAh pack and is easier on the packs which if used correctly should result in a longer-lasting pack.

F3A rules state the maximum voltage is 4.299 
For practice and non-regulated events charging to 4.35 is probably undetectable.
Note: This may require a charger capable of HV charging above 4.2 volts per cell to get maximum mAh.
It is OK to charge to 4.2 volts and use normally.

Lighter packs are the result of: A more advanced ceramic diaphragm and electrode tab with high capacity density are now used during cells' production.

Note the following;

High Voltage cells can be charged to a maximum of 4.35 volts per cell. Normal voltage cells are charged to 4.2 volts per cell.
The capacity of this pack is dependent on the charge.

 

 Note:

The difference between the 4.2v per pack and the legal limit of 4.5 volts per pack for AMA Pattern rules Classes Sportsman thru Master makes a huge difference in the capacity in the pack. These are proven to be the new "Gold Standard" of lipos for the highest performance.

 The FAI rules for the competition are FAI tech reg 5.1.2.b) states Electric powered model aircraft are limited to a maximum of 42.56 volts for the propulsion circuit.
