High-Performance Batteries for the EV enthusiast
75/100C Peak "Sleeper Cells".  Drag Racing packs with the
highest KW/KG available and lowest $/KW.   3.7V cell chemistry,
remember to account for cell voltage and C rating to determine
final cost of your racing pack. As seen in DC Plasma,
Assault&Battery, and Panic in Detroit check out the links page
and the pictures of packs down below.
These cells will stay the coolest at identical amperage to any
other cells around. Measured at 1millohm each. Sag is the
minimum when resistance is the lowest.


Our packs are most commonly built around a 1P6S "module".
$150 per 6S module of 4.5Ahr at 100C Drag racing duty.
Planning Size each module is 2"x2"x8" at 0.78kg
Standard Lonestar EV Boxes are $500 assembled
To calculate your pack check out the pack design plots, called
PVI diagrams, below.  Find your needed amperage on the left
and your needed power from your battery on the bottom. Find the
place where they cross and select a battery discharge curve that
is close. The battery discharge curve tells you what voltage the
pack will sag to under drag racing load.

Here is an example of a recent pack we built
8P30S 3600A 125V charged $5400 Complete.
8P90S
(1200BHP peak @375V charged max for a Zilla) $15,500
Each 8P30S pack is approx. 60-70lbs.

In addition to Orion BMS systems we can supply, we sell a
Battery Balancing System (BBS) that can be removed from
vehicle after charging while you go race. They are $500, balance
up to 36 cells from your pack at a time. See pictures below.

Custom Packs Available, packs can include BMS, shunts, contactors,
fuses, etc....  Pack construction by Lonestar EV Performance.

Ampahaulic DC-DC Converter 100Amps for high voltage
DC packs.
Open board Kit for those high voltage packs that just can't find
enough power from other sources.










  • Input range 200 VDC to 700 VDC.
  • Maximum input current 10 amps.
  • Bus load with control circuit off, 90 K-Ohms.
  • Input capacitance 80 uF maximum.

  • Control "ignition" input voltage range 10 to 28 VDC
  • Current drawn by control lead < 150 mA

  • Output voltage 13.8 volts DC +/- 5%
  • Output current 100 amps maximum
  • Output protection auto-reset electronic current limit
  • Guaranteed to survive output short circuit but fuse may blow if
    resulting input current draws down input voltage.
  • PCB dimensions 4" by 16" component height is approx. 4"
    depending on cooling option.
  • PCBA operating temperature range -40 to +70 C
  • Cooling water temperature range -20 to +80 C at outlet.
  • (Minimum inlet temperature depends on flow rate.)
  • Input protection non-resettable fuse. (Excess voltage or
    reverse polarity may damage unit.)
  • (and if anybody would want to they can be paralleled along
    common input and output bus bars for increments of 100 amps.
  • Comes standard air cooled requiring case fan but optionally can
    be fitted with water cooling as shown below.
Here is a shot from one customers build with an acrylic
box, water cooling option and remotely operated relay
panel built in.
