Systems batteries for UAVs capable of lifting heavy payloads or for long flights

[CMEC]

Systems batteries for UAVs for longest flights and capable of lifting heavy payloads.
Handmade to order and ready to use. Designed & assembled in the Netherlands.

Panasonic NCR18650GA li-ion cells. High energy density. Never compromise. Ultra durable.
Battery quality is extremely important. These kind of cylindrical Li-ion cells used to power electric vehicles Tesla have at least 70% more energy density per weight and are less heavy than Li-Polymer types.

For UAVs which are suitable for various industry applications, such as television broadcasting, signal relay, video surveillance, surveying and mapping, aerial photography, pipeline and powerline patrol, medical aids, agriculture, a battery pack assembled with cell type 18650 with high energy density it is translated into a 70% longer flight time, or more heavy payloads!

Another big benefit:
With more cylindrical batteries 18650 Li-ion type, interconected in parallel, the battery pack has more power and it’s more safe, because entire power supply system can’t fail, unlike battery pack with Pouch Li-Polymer cells are only connected in serial , if only one fails, drone is in freefall.

How It’s Made: A clean, safe and precise engineering design process!

Cells are extra-insulated with a gasket against short-circuit (the outer rim of the top of the cell is part of the negative terminal). Then are exactly welded and assembled, spending more atention to detail and safety. Inside pack, under cabling, the cell block is surrounded with a laminated aramid fiber shield (0.50 mm)

About order, payment and delivery.

Order processing time: 24 hours. Manufacturing process: 5 – 30 days, depending on item quantity ordered. Payment metode: through invoice (Direct bank transfer or Paypal service). See below the price list for 3S / 4S / 6S battery pack configuration & go to the order page . Please make all payments in € (EUR).

Flight in confidence! The CMEC batteries has one of the strongest warranties of any battery pack manufacturer. Two Years Warranty (read instructions, cautions and warnings)

See below a chart with all battery packs assembled with Panasonic NCR18650GA 3.5Ah 10A, ordered by configuration, capacity and weight. Price list.

Instructions, cautions and warnings:

1. These battery packs are not protected by the internal BMS, and are manufactured for the intended to use with a external charger/controller with proper protection and balancing circuitry for this kind of lithium-ion cells (read below prohibited actions)
2. Because is a new battery pack assembled, the cells have from factory a voltage for storage state, and needs to be fully charged to 4.20V/cell before first use. After that, you can downgrade the charger setup to max. 4.10V/cell, for a long lifespan of battery. Also, don’t discharge below 3.10V/cell, for same reasons (read below how to prolong battery life)
3. CMIUTA Electric Company don’t have any responsibility and aren’t liable for any damage caused through improper use of these battery packs and chargers, or to use for purposes other than mentioned on product specifications.
4. CMIUTA Electric Company will not be liable for any problems caused by design defects of the electric vehicle, chargers or electronic devices, located in propriety of customers.

Prohibited actions (otherwise, the battery may catch on fire, smoke, explode, or cause heat generation)

• DO NOT short circuit
• DO NOT force a reverse-charge or a reverse-connection
• DO NOT overcharge or over-discharge
• DO NOT modify, disassemble, puncture, cut, crush, or incinerate
• DO NOT expose to liquids
• DO NOT use or place the battery a high temperatures (more than 80°C)
• DO NOT connect the battery directly with AC plug (outlet) or car plugs.

What shortens lithium battery life:

1. High temperatures.
2. Overcharging or high voltage.
3. Deep discharges or low voltage.
4. High discharges or charge current.

Do you have any videos, blogs, builds, etc. showing experiences with your batteries in action in RC UAVs?

 

[CMEC]

6S6P 60A battery pack was successfully beta tested on a geodrone. Continuous flying for more than 70 minutes, with a fully charged battery, so two times more than standard Li-po. See here the used vehicle. Go to: geodrone.fi

Just one suggestion regarding your chart, dimensions are very important to us hobbyists

 

[CMEC]

Are fully customizable, because exist many differences between vehicles. So I do assembling of this batteries on customer instructions about physical dimensions.

 

[GJH105775]

What about weight concerns and power density in comparison to pretty volatile the lipo sacks?

I could see this for camera quads, bu not so much for racers.

Pretty cool, someone else was trying to sell li-Ion packs and insisted that balancing/balance leads were unneeded. Nice attention to details on your packs. Nice to see you are using Sanyos.
