Product selling point:
1. The open heat dissipation system adopts the anodic oxidation technology of the heat sink to dissipate the temperature stably and safely to the outside
2. Any string of battery packs, zero voltage of the battery cell and any broken wire can protect the battery from no output.
3. GPS port, balanced protection; can be connected to weak current switch, temperature control protection
4. Elaborately made with high-quality components, so as to achieve a series of functions such as long service life, strong battery life, low charging and discharging temperature, etc.
5. Multiple optimized protection management schemes, which stably reduce the internal resistance of the circuit, improve the service life, and ensure safety and reliability
