FAQ
+ How long will my battery last?
Several factors that affect battery life including weather, temperature, recharge cycles, depth of
discharge (DOD), discharge current, charging current, charging method, vibration and duration of
static use can all have dramatic effects on battery life. A properly maintained battery should last
2000+ charge discharge cycles or 5times as long as lead-acid use in similar conditions.
+ Can I use lithium ion batteries with other types of batteries?
No. If different types of batteries are used together, or new batteries are used with old ones, the
difference in characteristics such as voltage, capacity, and/or internal resistance may cause
uneven discharge between the batteries leading to cell damage potentially resultant in fire.
+ Is it okay to use a universal lead acid charger with high enough charging current?
Using a lead acid battery charger is not recommended because they charge at a lower 2.30V to
2.45V per cell in addition to charging in multiple stages with a final float charge setting. This is
distinctly different from the Li-Ion 2-Stage charge profile. Mixing of chargers between chemistries
will result in insufficient charging and potential damage to the battery.
+ Can I connect two of the same Li-ion batteries together for more voltage/ capacity?
Linking our Li-ion batteries in series or parallel connection is normally NOT RECOMMENDED and
may exceed factory recommended usage parameters. It is recommended to purchase a single
battery with the requisite capacity and discharge characteristics. Our Battery Management
System (BMS) is designed for operations within a singular battery unit and we cannot guarantee
operability of multiple batteries connected together regardless of configuration. If, however,
multiple batteries are required, please ensure 1) the built-in BMS can support the operation in
parallel or series; 2) the batteries are of the same maker/model and from the same batch 3) peak
discharge is at <1.0C.
+ My battery will not be charged/discharged?
There are multiple reasons including but not limited to 1) charger failure, 2) external damage to
battery has compromised either the cell pack or BMS, 3) battery voltage has fallen to zero in one
or more cells, 4) there is a connection error within the pack, 5) a malfunction(s) has occurred
within the BMS component(s) or in extreme cases, and 6) extreme high/low temperatures may be
inhibiting charging efficiency of the cell pack itself.
+ Can I jump start a dead lithium-ion battery?
It is not recommended. Li-ion batteries enter an elevated sensitivity state when empty and the
introduction of unmodulated amperage in this state will damage the cell. We highly recommend
using our chargers to recharge a fully discharged Li-ion battery as our chargers have the sensing
circuitry required to modulate charge current to optimally recondition fully discharged batteries.
