Cautions and Safety
General Cautions and Warnings
The Electric Juggernaut is an electric tricycle that you can ride like a bicycle with the added benefit of
more stability on soft ground.
Refer to the All Purpose Bicycle Manual available on the Rungu USB drive that ships with the Electric
Juggernaut to new customers or online at this link
2
.
WARNING: Being a tricycle, the Electric Juggernaut has a tie-rod that connects the two
front forks. DO NOT USE the tie-rod to lift the trike. The steering uses the tie rod as a hard stop so the
forks don’t rub against the front wheels. Grasping the tie rod when lifting WILL RESULT IN A PINCH TO
THE HAND AND FINGERS THAT MAY LEAD TO HAND OR FINGER INJURY. ONLY GRASP PARTS OF THE
FRAME OR SADDLE TO LIFT THE TRIKE.

Battery Safety (Brief Overview)
NOTE: If you ever suspect a battery problem, please contact Rungu Support immediately by email or
phone so we can go through the appropriate steps/procedures to make sure everything is okay with
the battery system.
At Standard Bearer Machines, safety is our number one concern. Standard Bearer Machines wants our
customers to enjoy an excellent product that will give those customers years of trouble-free operation.
As much effort as Standard Bearer Machines partner, Hi Power Cycles, makes to minimize the risk of
these state-of-the-art batteries, there are always safety concerns when it comes to Lithium batteries
that we want our customers to be aware of. All the new portable electronics, including cell phones and
laptops, contain lithium batteries which have the same chemical properties, although bike batteries are
on a much bigger scale. Hi Power Cycles makes every effort to have the highest quality battery cells and
best battery protection (called a BMS or Battery Management
System) to minimize any risk associated with these high-power
batteries.
Hi Power Cycles has gone through extensive research and testing
to get the best electric bike batteries in the world. The battery
chemistry is the same that large car manufacturers (such as
Nissan) use in their vehicles. This state-of-the-art battery
chemistry is called Lithium Nickel Manganese Cobalt
(LiNiMnCoO2) or NMC for short. Hi Power Cycles feels that this is
the best overall combination of power, safety, performance, and
life span compared to the other options available.
Due to the nature of lithium cells, which have a lot of energy stored in a small package, there is always a
possibility this energy can be suddenly released and can cause fire and/or serious injury if not taken care
of immediately. With a state-of-the-art Battery Management System that is found on all of our battery
packs, the cells and pack are protected from failure. The only time a pack will fail will be a result of a
BMS failure and attempting to charge, short circuit, over discharge, or somehow puncture the battery
pack.
The main cause of failure in lithium batteries occurs during the charging portion, when cells can be
overcharged. This is the number one failure and can lead to batteries which vent and eventually release
all their energy at once (or can even cause the battery pack to ignite on fire). Due to a BMS failure, cells
can get out of balance and certain cells may become overcharged as a result. Therefore Hi Power Cycles
always recommends monitoring the charging process in the extremely rare event something should
happen.
Caution: Charging on a concrete floor, such as in a garage, away from debris and material is always
recommended as a safety precaution.

Battery Safety Precautions
Hi Power Cycles recommends keeping the following immediately accessible where you charge your bike
•Class D Fire Extinguisher: can be used in the event of a lithium fire
•ABC Fire Extinguisher: If you cannot get a Class D, this will do the job by preventing other
materials around the ruptured battery from catching on fire.
If your charger typically takes 4 hours to charge your battery, but it seems to be taking longer, unplug
the battery and investigate. If you suspect a bad BMS, smell the top of the battery. If there is a burnt
smell, it is a failed BMS and stop charging immediately. If nothing is wrong, it is okay to continue
charging as the battery is simply balancing while it is charging and it may take longer than normal.
If, for whatever reason, your bike suddenly has a loss of power and you are not getting the same
performance, STOP IMMEDIATELY. Turn the bike off and inspect your battery system. Check for a burnt
smell and inspect there are no melted or shorted wires. This would be indicative of a shorted or failed
BMS which you will need to contact us directly to take care of.
If you notice that your battery system has a puffed, damaged, or leaking cell, contact Rungu Support
immediately and we will walk you through the appropriate steps to take in this instance.
Catastrophic Battery Failure
Although extremely rare, all lithium batteries are capable of catastrophic failure if mishandled or
treated. The following are guidelines for a battery pack failure. Great caution needs to be exercised
during a catastrophic battery failure.
Warning As soon as a problem is detected (battery is hissing, you smell a burning smell, it is billowing
smoke etc), take battery system or bike outside immediately, away from all structures and people,
preferably on concrete (like a driveway).
Observe the battery pack from a safe distance to see if it is a pertinent problem that needs to be
addressed immediately. Monitor the battery pack until the cells drop below critical temperature and
start to cool off. Contact local authorities if necessary!

Battery Safety (In Depth)
Main reasons a battery pack will fail:
•Short-circuit
•Charging
•Forced over-discharge
•Excessive heat or incineration
•Crush, puncture, or disassembly
While Hi Power Cycles have designed their cells and batteries to be tolerant of adverse conditions, these
very active chemical systems have limitations. Certain hazards are associated with exposure to heat and
its subsequent effects on sealed cells. These hazards include the potential for cell venting, explosion,
and/or fires. The initial source of heat can be external (welding, soldering, etc.) or internal such as
heating caused by short circuiting, excessive running currents for prolonged periods of time, forced
over-discharge, charging, or excessive mechanical abuse. Specifically, mechanical abuse in the form of
excessive shock or vibration can result in case deformation, crushing, and damage to the electrode
materials.
Warning: Not guarding against these conditions may result in a hot cell or a battery pack that could
vent or explode.
The intent of this section is to provide a general knowledge of how to handle cells and batteries that
have been subject to these adverse conditions. This document will focus on the following:
•Hot cells
•Leaking or venting cells
•Cells that have exploded
•Fires involving lithium batteries
•The guidelines in this document are minimum recommendations.
Only trained and equipped emergency responders shall be allowed to respond to a vented cell incident.
Consult federal, state, and local regulations for emergency response regulations.
Hot Cells
A hot cell is a condition that arises due to a short circuit of the cell or battery, either internal or external.
The cell/battery temperature rises as the event continues which can lead to the cell reaching critical
temperature and the potential to vent or explode.
Vented Cells
It is unlikely that any lithium battery would explode. These events are rare and are usually the result of
an abusive condition or misuse that raises the cell temperature above its critical point.

V2.2 RUNGU Electric Juggernaut User Manual –2017 model year

In the event of a lithium battery explosion, a room can quickly fill with a dense white smoke that can
cause severe irritation to the respiratory tract, eyes, and skin. Precaution must be taken to limit
exposure to these fumes.
Response Procedure
•Monitor the temperature from a safe distance using a non-contact thermometer or thermal
imager
•If temperature monitoring equipment is not available, keep the area evacuated and secure and
do not handle the cell/battery for at least 24-hours
•If the battery cools, continue to monitor until it reaches ambient temperature
•Remove the battery from the area once it is cool
•Dispose of the cell in accordance with waste or recycling protocols
•For more information on Lithium batteries, please visit Battery University as a source of
knowledge
