Introducing and re-introducing the Sleeper Cell battery systems and components.
High and ultra high discharge for the most demanding electric operations.
We sell individual lithuim ion pouch cells, modules (2S-12S), fully loaded custom made packs and complete battery systems with fuses and battery management system gear.
Module Classes from left to right(1st image)
12S 44.4v 5000mAh 125C with 8mm PRC shrouded bullet connectors
6S 22.2v 5000mAh 125C (doubled power leads)
6s 22.2v 4400mAh 75C
3S 11.1v 5000mAh 125C
2S 7.4v 5000mAh 125C (unterminated)
All individually sold modules come standard with 8mm PRC shrouded bullet connectors.
All 6S-12s modules come with 6S Polyquest BMS taps. 12S modules are equipped with 2x 6S Polyquest BMS taps wired in series to make them easier for customers to connect 6S standard battery balancing tools.
We can produce battery pack cases with the following materials
G-10 (G-7)Garolite flame retardent FRP panels
Welded metal (steel, stainless and aluminum) with insulation inside
Typically made with 3/8" polycarbonate panels.
Anderson SB connectors for power leads
Orion BMS2, DB37 (discontinued) or Polyquest cables out
Cheapest option. Most popular.

2nd image Junior dragster Pack with DB37 cable
3rd image with 6x 6S Polyquest reader cables
Typically made with a mix of 3/8", 1/4", and 1/8" panels.
Same output options
G-10 has 280° F max temperature, has way more impact strength than polycarbonate and is more rigid.
Images show hybrid polycarbonate and G-10 panel construction with panel mounted output hardware (37-pin D-sub) and direct bullet connections through semi-open lid.

We offer two options for a BMS system
Orion BMS2 System
Lonestar Internal Balancing Boards
An Orion BMS2 is a premium BMS system with loads of cell monitoring, thermal monitoring, data logging and charger current control options.
Our Lonestar Internal Balancing Boards are a budget option for those that want a passive balancing device with some charger relay safety control.
Right now we internally wire battery packs standard with 8 gauge copper wire with either a mix of bullet connectors/crimp connectors or 100% bullet connections. To get maximum performance from batteries battery cell connections must be busbar connections which we don't have the equipment to manufacture at this time. We recommend referring to the conservative numbers on the spec sheet for wired battery packs.
