LiGo 10X

Introduction

Grin's modular LiGo battery family was born in response to the transportation restrictions placed on large lithium ebike packs. Properly certified batteries under 100 watt-hours can ship with many fewer restrictions than large packs, and are even allowed aboard passenger aircraft with your carry-on luggage. The LiGo battery concept involves creating small stand-alone 99 watt-hour modules which can be easily stacked together in parallel to form a single large battery, but broken down for shipping.

Our original LiGo and LiGo+ modules (2016-2022) had all the cells in 10x1 row, and relied on two pairs of wires with Anderson Powerole connectors for the mating hookup. The replacement LiGo 10X devices have the cells in a more compact 3x4x3 layout with a clip-together mechanical and electrical interface.

10X Features

36V 2.75Ah pack, can stack as many in parallel as required
Rugged metal enclosure handles drops and impacts
FOUR Integrated XT60 connectors (2M + 2F) per module
Mechanical twist lock and clip latch hold connector packs secure
Includes overhanging lip for sliding into battery rail on bike
BLE wireless connectivity with cell phone and see individual cell data and settings
Integrated momentary push button for on/off and other functions
Ultra low quiescent current drain (<2uA in ship mode)
Five embedded RGB LED's for state of charge and other information
No spark when plugged into capacitive loads
Cell balancing at all voltages, not just full charge
IR compensated over-charge and over-discharge current protection (no premature cutoffs from high current)

Connectors

Each battery has two male and two female XT60 ports. All ports share the same common bus and have the same voltage and can be used either for charging or discharging. If used with the battery mounting rail, the two male XT60 pins will mate with the rail dock, leaving the female XT60s exposed for accessories. The dock itself may contain additional connectors (e.g. ST3 or DC 5.5 ports for charging, Anderson Powerpoles for discharging etc.)

Latching

When two LiGo 10X batteries are connected together, they are secured together by four mechanical latches and not just the mated XT60 plugs. On the top of the pack, two snap latches over the XT60 connectors click together automatically and must be depressed to be released. Meanwhile, on the bottom of the battery are two twist lock latches. These rest flush to the surface when disconnected but fully lock the bases together when rotated 90 degrees. Please see our short Instagram video to see how this works.

Rail

The LiGo 10X rail is machined from aluminum and can be secured to bike frames either through water bottle eyelets or with hose clamps. It is available in various lengths

(for max of 3, 4, 5, or 6 LiGos) and has internal spring latches that click and hold the LiGo battery from sliding off. Each rail can hold from 2 to the max number of LiGos and

has two docking options for the pack. Either a basic dock for external controllers, or a folded sheet metal dock that allows for an integrated Baserunner.

Certifications

The LiGo 10X complies with UN38.3, EN15194, EN62133-2, FCC/IC/CE EMC/EMI, and is compatible with the regulatory requirements governing ebike battery packs in most

corners of the world, except...

What about UL2271?

Unfortunately, although we designed the LiGo 10X BMS to comply with the American UL2271, during the testing phase the standard was updated in a way that prevents the

BMS from complying without an extensive redesign that could significantly reduce performance without increasing safety, and would require complete retesting against the

other standards. Since the LiGo 10X battery was built with safety protections beyond the standards it meets and exceeds those of other products on the market, we don't

think it makes sense to delay the release of the LiGo10X Battery further.

For individuals who require a UL-listed battery for various insurance or bylaw reasons, we are planning to complete a UL2271:2023 compliant LiGo 10X battery in 2026 that

we will offer concurrently with the Non-UL pack. It will be more expensive due to a doubling of the number of mosfets, but we will work hard to limit the performance

reductions stemming from that requirement.

User Manuals

Please read the official user manual to have a full understanding of the LiGo 10X battery and it's many capabilities. For OEM customers looking to more deeply integrate the

LiGo 10X into their system design, we've also published the complete wireless protocol. This will allow your system to connect with each LiGo module and interrogate the state

of charge, cell voltages, usage history, and other details.
