IMPORTANT SAFETY INSTRUCTION
-
Please keep the battery away from heat sources, sparks, flames, and hazardous chemicals.
-
Maintain Adequate Ventilation and Heat Dissipation
Place the battery in a well-ventilated area with sufficient heat dissipation to prevent overheating and damage. -
Size the Battery Cables and Connectors Appropriately
Use high-stranded copper connectors and heavy gauge cables to handle possible battery loads. Make sure to keep identical cable lengths. Avoid accidents caused by unsuitable connectors or cables that make the connection a heat source during battery operation. -
Please tighten all cable connections, as loose cable connections can cause terminal meltdown or fire.
-
DO NOT puncture, drop, crush, burn, penetrate, shake, or strike the battery.
The battery should be securely fastened during handling to prevent impact or dropping. It should be safely secured to a solid plane and the cables safely tied to a suitable location to avoid arcing and sparking due to friction. DO NOT press it by placing heavy stuff on top of it for long periods, which may damage it due to an internal short circuit. -
DO NOT immerse the battery in water whether the battery is in use or on standby.
-
DO NOT open, dismantle, or modify the battery.
-
DO NOT touch the exposed electrolyte or powder if the battery casing is damaged.
-
Uncovered electrolyte or powder that has contacted the skin or eyes MUST be flushed out with plenty of clean water immediately. Seek medical attention afterward.
-
Avoid Short Circuit
Please use circuit breakers, fuses, or disconnects that have been properly sized by certified electricians, licensed installers, or regional code author- ities to protect all the electrical equipment in your system. The battery has a built-in battery management system (BMS) that protects the battery cells from over-charge, over-discharge, and over-current, however this alone will not protect your system from severe electrical conditions.

CHARGING METHODS
SOLAR PANEL(S) & CONTROLLER
- Solar Panel
- Recommended Power: > 200W
- The battery can be fully charged in one day (with effective sunshine 4.5hrs/day) by 200W solar panels.
- It may take more than one day to fully charge the battery by ≥ 200W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.
Controller
- Recommended Charging Current:
lOA (0.2C)| The battery will be fully charged in around 5hrs to 100% capacity.
---|---
25A {O.SC)| The battery will be fully charged in around 2hrs to around 97% capacity. - Recommended Charging Mode: 12V (14.6V) LI (LiFeP04)
Controller Settings
Refer to the below parameters if you need to manually set up your controller.
As different types of batteries have different charging modes, it is
recommended to set only the following parameters for LiFePO4 batteries. The
settings for other types of batteries do not apply to LiFePO4 batteries except
for the following settings.

HOW TO CONNECT BATTERIES
Step1 Wear Insulating Gloves
Wear insulating gloves for protection before connecting. Please pay attention
to operation safety in the process of connection.
Step2 Voltage Balancing Before Connection
Below two steps are necessary to reduce the voltage difference between
batteries and let the battery system perform the best of it in series or/ and
in parallel.
- Fully charge the batteries separately. (voltage at rest: >13.33V)
- Connect all of the batteries in parallel, and leave them together for 12~24hrs.
- They’re now ready for the connection.
Step3 Battery-to-Battery Connection
-
Connect Batteries in Series
After a series connection, the voltage of the battery system will be doubled according to the number of batteries you connect. E.g. If two 12V 50Ah TM batteries are connected in series, the battery system will be 24V (25.6V) 50Ah.
-
Connect Batteries in Parallel
Refer to Page 11 for total input & output connection After parallel connection, the capacity of the battery system will be doubled accord- ing to the number of batteries you connect. E.g. If two 12V 50Ah TM batteries are connected in parallel, the battery system will be 12V (12.8V) 100Ah.
-
Connect Batteries Both in Series & Parallel
Connect in parallel first, then series. -
Connect the batteries in parallel.
-
Connect the paralleled battery systems in series.
Step4 Total Input & Output Connection
Use two copper bars (instead of battery terminals) to connect all the positive
and negative output/input cables, ensuring that the input & output currents of
each battery are balanced. (Not required when connecting batteries only in
series.) It is not recommended to use one terminal as the total positive or
negative o
utput/in- put of the
battery system as the connected terminals may heat up or even melt if the
total output/input current of the battery system is too high.
- As of 0 / 3 / 0 / 0 is connected in series with of @/A/Q/8, please do not connect of 0 / 3 / 5 / 0 with of load or of 2 / 4 /6 / 8 with
- of load, otherwise the battery system will fail to connect in series.
- Please do not connect in reverse order, which may affect the use of the batteries.
Step 5 Rebalancing Every 6 Months
It is recommended to rebalance the battery voltage every six months following
Step 2 on Page 9 if you’ re connecting multiple batteries as a battery system,
as there might be voltage differences after six months of the battery system
running.
FAQ
