Its a pity these cells are Lithium Cobalt and not the more friendlier
chemistries.
The spec states a charge temp from -20C! I didn't think Lithium cells like to
charge below 0C.

It's probably wishful thinking, but
it would nice to have these available
through EV parts dealers:
Boston-Power Launches Ensemble™ Module System
Highly Scalable, Highly Reliable, “No-Weld” Integration
System for
Automotive and Industrial Battery Module Solutions
WESTBOROUGH, Mass. and BEIJING, CHINA, Sept 16th, 2014 -
Boston-Power Inc.,
an industry leading developer and manufacturer of
lithium-ion (Li-ion)
batteries and energy storage technologies, today announced
its launch of the
Ensemble Module System; a revolutionary “kit” of
standard components that
allows OEMs and pack assemblers a simple, cost-effective way
to assemble
large format battery pack solutions for electric vehicle
(EV) and energy
storage system (ESS) applications. Available in 155 Wh and
116 Wh
increments, module designs can be created to meet a wide
variety of voltage
and capacity requirements.
Companies in need of large format battery packs are faced
with spending
significant time and expense in designing, qualifying and
fabricating custom
solutions to meet their requirements. Boston-Power’s
Ensemble Module System
provides a semi-custom cell-to-module approach to quickly
and easily
integrate Boston-Power’s cells into high energy density
battery modules.
For OEMs and pack assemblers, the Ensemble Module System
accelerates time to
proof of concept, prototype and most importantly market
while reducing
upfront capital investment, program risk, BOM complexity,
labor cost,
production yield and operational complexity.
“The Ensemble Module System offers a game-changing
approach to building
large battery packs for our customers,” said Darren
Bischoff, Director of
Business Development and Marketing for Boston-Power.
“First, the flexibility
of the Ensemble system allows customers to design, build and
test a
prototype pack in a fraction of the time it would typically
take for a fully
custom solution. Next, the production quality components
used in the
initial prototypes greatly reduce the pack qualification
effort needed to
launch into mass production. Finally, the same
highly-reliable standard
components used in the prototype and development stages
support a
cost-effective launch of low, medium and high volume packs
without the need
for expensive tooling or a complex assembly line. Ensemble
provides clear
value from project inception through high volume pack
production.”
Key to the Ensemble solution is its innovative
pressure-connect approach to
module assembly which completely eliminates the need for
difficult, costly
and time consuming cell welding. Fully tested to
automotive quality
standards, the result is a mechanically robust module that
can be assembled
and disassembled in a fraction of the time of conventional
methods. By
utilizing Boston-Power’s Swing Cell products, customers
realize all of the
ease of assembly benefits of large format modules while
retaining all the
advantages of packing density, reliability and thermal
performance that come
with using Boston-Power’s small form-factor battery
cells.
The Ensemble Module System enables cost-effective battery
module packaging
and mounting solution with exceptional performance at any
volume. Sample,
prototype and production volumes are currently available.
The kits appear to be based on their 18650 lithium cobalt
cells made in
Shenzen:
