Описание товара
Sandupower 72V OEM Lithium Battery Protection Board SDA175 20S 50AC 50AD for Ebike Lithium Ion Battery Rechargeable Battery Packs
Item Name：Power battery protection board
Model No. ：SDA175-20050A203ALM1S
Item Spec. ：20S ternary Same port 50AC 50AD
Application：Lithium Ion Battery rechargeable battery packs and so on,commonly used in ebike batter
Product advantages:
1. Drop protection: protect the battery without output.
2.Integration program: Roma integration program.
3. Small body and big energy: the new MOS tube has low internal resistance.
4. Stable heat dissipation: open heat dissipation is more stable.
5.Over-voltage protection: to prevent excessive battery pressure.
6.Over-discharge protection: prevent the battery from over-discharging.
7. Three anti-silicone: dust-proof, moisture-proof and anti-static, safe to use.
8. Temperature control protection: electronic NTC over-temperature protection, safer to use.
