About our battery's BMS
The unique built-in battery management system (BMS) of our products lithium battery can protect it from overcharge, deep discharge, overload,overheating and short circuit, and low self-discharge rate. Our BMS has a high temperature disconnect function. When the internal temperature of the battery reaches 75℃ ( 167°F ) it will automatically disconnect to protect the battery. With overcharge and over discharge protection functions, when the overcharge voltage exceeds 15V or the over discharge voltage is lower than 8.8V, the battery will automatically disconnect. Our recommended charging voltage and discharging voltage are 14.6±0.2V and 10v±0.2V, respectively. If the charging voltage is lower than 13.8V, the battery power (with a deviation of 1-2°/o) cannot be fully charged.
About our battery's cell
Lithium-ion batteries have high energy density and high average output voltage, The self-discharge is small and there is no memory effect. The wide operating temperature range is -20℃-60℃. Excellent cycle performance, fast charging and discharging, charging efficiency up to 100%, and high output power. long lasting. It does not contain toxic and hazardous substances and is called a green battery."
About the parallel and series of this 24V 100Ah batteries
We suggest that:
1. The Max connection in series is: 2 pcs batteries to 48V
2. The Max connection in series/in parallels: Support 2 series and 4 parallel (in the case of simultaneous series and parallel connection)
3. The Max connection in parallels is (In the case of separate parallel connection, no series connection): it can connect multiple batteries, and no more than 10 pcs in parallel.
Products of different manufacturers and different capacity batteries cannot be connected in series or in parallel. When the batteries are used in parallel or series, the voltage must be the same. It can support fast charging and solar panel charging.

This battery does not have a low temperature heating function. Please do not charge the battery in a temperature lower than 32°F (0℃) to avoid damage to the battery.
1, Charging Temperature : 32°F（0℃ ) to 122°F (50 ℃).
2, Discharge Temperature : -4°F ( -20 ℃ ) to 140°F ( 60 ℃ )
How to charge the battery?
Scheme 1: You can use a lithium iron phosphate 28.4V-29.2V charger to charge the battery pack.
Scheme 2: You can use photo voltaic solar panerls to charge the battery through MPPT.
Scheme 3: You can use the inverter to charge the battery pack (note: the inverter needs a built-in AC to DC charging function)
