2nd
Generation High Current Rechargeable Lithium BatteriesDue
to limited resources we cannot accept new customers for these cells, sorry.
(Except for 12V 55AH
packs, click here)

Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for
OEMs in a hurry!
These li-ion cells and batteries not only
have high capacity, but can deliver high power. One 12 AH cell can supply 130 watts, a 4 cell pack can supply over 500 watts at
12 volts. High-power lithium ion batteries are now a reality. They can be used as storage cells or power sources.
All of the following products are available. Chargers and battery management boards are available. We are now offering total
turn-key solutions for almost any capacity and voltage made of the following building blocks. Delivery is typically 8 weeks.
For faster deliveries see the
large format lithium polymer power cells.
12 Amp Hour Cells
60 Amp Hour Cells
Battery
rechargers
Chargers are available to recharge battery packs from 12 Amp Hours to 400 Amp Hours, 3.6 volts to 400 Volts.
They are constant current--constant voltage, terminate at 100 mA algorithm.
** Chargers for any number of cells are readily
available with 3-5 week lead time.
Battery
management boards
The battery management board is essential to maintain a safe, long lived battery pack. They have the
following functions.
1. Balance charging current among the cells in the pack to insure all cells are fully and evenly
charged.
2. Protect the cells in the pack from overcharge.
3. Protect cells from overcurrent.
4. Protect the pack
from short circuits.
5. Protect the cells in the pack from overdischarge.

Packs
Packs can be made to your specification, both in series, or series-parallel. For example a 4S2P (4 series 2
parallel) pack can make a 14.4 volt, 24 AH pack out of 8 3.6 volt, 12 AH cells.
Advantages:
 State of the art lithium-ion cell with laser welded stainless
steel cases, no polymer, rubber, or plastic seals.
Cells under development or available from 3AH to 60
AH.
High Discharge
rates
Priced competitive with other
battery chemistries. |
