• Please ensure to fully charge each battery before connecting in series or parallel.
•If the battery top cover has alabel showing number 1-N, such as 1-1, 1-2, 1-3, 1-4, that means
the batteries are grouped in manufacturing factory, to ensure the high consistence in case batteries
would be connected in series or parallel. The first number is the group number, and the second
number is the sequence within the group. Please do not mix different groups of batteries.
• The battery can be connected in series up to 4batteries, or in parallel up to 2batteries. Take
12V100Ah for e.g., 4batteries connected in series can create a48V100Ah battery bank; and 2
batteries connected in parallel can create a12V200Ah battery bank. If you want to use them in
series and in parallel at the same time, please contact the dealer for a solution.
* "Equalization mode"
* "Desulfation mode"
* "Pulse function"
•DO NOT leave the lead-acid battery charger connected to maintain or store the battery, because
most will NOT maintain the proper voltage charge algorithm for lithium batteries and damage will
occur to the battery.
• If you want to charge abattery with lead-acid charging system, make sure the charging voltage is
less than 14.6V. If charging batteries in series, make sure the charging voltage is less than 14.6V
times the series number. For e.g., if you want to charge batteries in 4series, the charging voltage
should be less than 58.4V, and the charging current must follow the instruction in “Charging
Instruction”.
• Please do not exceed the maximum discharge current in this User Manual.
•Do not discharge the battery with maximum discharge current several times in succession, since it
may cause battery damage.
•The maximum continuous power for 12V100Ah, 12V150Ah, and 12V200Ah should not exceed
1280W. i.e., they can support 1000W inverter, but the maximum continuous load should not exceed
1100W (according to conversion efficiency 85%).
• Do not mix a new battery and a used battery in a same configuration.
