MaxAmps High Capacity and High Discharge 18650 Lithium-ion Cells.

MaxAmps has released a new line of 18650 lithium ion cells. The 3450Mah cell is a high capacity option for low draw applications and the 2150Mah cell is designed for those high amp draw applications.

MaxAmps releases new high capacity and high discharge 18650 lithium-ion cells.

From MaxAmps

MaxAmps is proud to announce the newest additions to our battery lineup. The MaxAmps 2150mah and 3450mah lithium-ion cells were developed and tested to take advantage of both the highest capacity and highest discharge options in the 18650 lithium-ion cell size.

For high discharge, we have found the MaxAmps 2150mah 18650 lithium-ion cell to hold the highest voltage under a load of all the cells tested. This is the perfect option for all of those amp hungry setups. Pulling 30amps has never been easier.

SPECS:

  • Nominal Capacity: 2150mAh
  • Maximum Discharge Current: 30A
  • Positive Terminal Style: Flat Top
  • UNPROTECTED(No PCB)
  • Nominal Voltage: 3.6V
  • Minimum Voltage: 2.5V
  • Maximum Voltage: 4.2V
  • Standard Charge Current: 1.075A(0.5C)
  • Maximum Charge Current: 2.15A(1C)

3450mah 18650 Lithium-ion

On the other side of the spectrum where runtime is key the 3450mah 18650 lithium-ion cell provided more runtime than any other cell at its size. Run longer and charge less with this high capacity option only available from MaxAmps.

SPECS:

  • Nominal Capacity: 3450mAh
  • Maximum Discharge Current: 5.175A
  • Positive Terminal Style: Flat Top
  • UNPROTECTED(No PCB)
  • Nominal Voltage: 3.6V
  • Minimum Voltage: 2.5V
  • Maximum Voltage: 4.2V
  • Standard Charge Current: 1.725A(0.5C)
  • Maximum Charge Current: 3.45A(1C)

Custom Packs

We can also build custom packs based on your requirements using these cells. Just send us an email or give us a call for a quote.

Well, 18650 is the way to go I believe , will wait and see how these fair after they've been put through the wringer a few times but hopefully they perform as stated .

If am assuming correctly, these are meant to be used for (or common use would be for) rx packs?

The high discharge cells for HV servos?

I recently bought an old school F3B glider because I've been missing flying a bigger glider, and it's all that I could afford right now. I am currently researching as to what rx pack to go with, replacing what came with it, a 5s 600mah NiCd pack, which I've got to assume is old as dirt and should be replaced. The pack is configured into a triangle at the rear (one cell on the bottom & two cells on top of it) and two cells inline in front of the triangle along the bottom.

I'm considering;

5s NiMh 2100mah range
2s 18650 Li-ion 3000mah range with BEC
others?

18650 is the size. They are the same size as the 1100 mah A123's. 18mm dia x 65mm long nominal.

They look .706" in diameter but not 25.590" long!

pull up -- PULL UP!!!
Typical high discharge 18650s measure about 18x65mm, weigh about 45g and cost about $6.

You are correct Mike. I will correct my post.

Why do I think they are not POSSIBLE in that size ? If really LIFEPO4 ?


Must have PAPER THIN metal strips to get that much cell area. To generate high currents. The insulators would also be paper thin also.

DO NOT EVER drop on an anything hard & reuse. I would fear a hot spot developing. Where does it say LIFEPO4 ? The voltages read like it is a LIFEPO4. Would check with the company before buying.... Would use them if the life is even only 10 years. Like A123 are.

Shelf life characteristics ?

Some of the specs are unknown , but , The use of 18650 in more consumer devices and Tesla's involvement and need for mid-high quality batteries has helped increase the performance of 18650's. The VAST majority will of course still be your typical low performance offerings but there will be manufacturers who see the use of a more attractive hard cased version of a LiPo as the way forwards.

Spec Voltages read like a LiCoO2 cell, not LiFePO4.....
What voltages were you referring to?
