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
1000+ charge discharge cycles or three times 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 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 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 batteries are from the same batch 2) the batteries are of the same
make and model and 3) peak discharge is maintained at <0.5C peak.
+ My battery will not charge/discharge?
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 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.
