Uncompromising Quality、Reliable BMS System、Low Temperature Protection Function、Auto-balancing Function、Stable and efficient structure that defies the elements and bumps.

The internal use of our battery is a square aluminum lithium-ion battery, the positive material used is lithium iron phosphate, compared to the market ternary lithium batteries, lithium iron phosphate higher safety, longer service life.

Can be used in series, the maximum number of series connection is 4, also support parallel connection, parallel connection before the battery needs to be fully charged and measure the voltage of each battery, it is recommended to control the voltage difference of the battery below 50MV to prevent the impact of battery life.

No, you can't. All the batteries you connect together should be the same capacity (Ah), the same voltage (V), and most importantly, the same battery type. And it would be better if they come from the same brand.

To avoid cycle life shortening, it is recommended not to discharge the battery below 50%. And when not in use, we recommend charging it 100% before storing it and recharging it after three months.

The discharge and charging temperature range is -4°F to 113°F (-20°C to 45°C). Use of this battery at temperatures below or above this range will shorten the life of the battery. We recommend checking the specific daily temperature of the place you are going before using MaxOne LiFePO4 batteries.

This Acoucou MaxOne LiFePO4 Battery enables more than 3000 charge/discharge cycles at 100% DOD (Depth of Discharge) in cyclic applications.Meanwhile, after testing,80% DOD 4000+ Cycles,50% DOD 6000+ Cycles.

If the selected charger doesnt matche the battery parameters, the battery will not be charged.LI batteries in parallel must have capacity (Ah), the same voltage (V), model and brand, otherwise LI batteries in parallel will not be charged fully.

In winter when the lithium-ion battery is too low, it should be charged in time, do not estimate the battery power in winter based on the normal battery life, and when the temperature is below zero degrees, take care not to charge outdoors.
