Battery Management System(BMS)

XK-154 7S 25AH (OR BELOW)

• Suitable for Lithium Manganate / Lithium Cobaltate / Lithium Ion / Lithium Polymer / Ternary battery packs.

• High-concentration conformal coating is fully covered, moisture-proof, leakage-proof, shock-proof, dust-proof, anti-corrosion, anti-aging, etc.

• Partial epoxy resin covering, enhancing waterproof, shockproof and other properties.

• The main control IC adopts a highly integrated special battery protection IC with reliable and stable protection function, low self-loss and anti-ESD. Each battery has an independent balance function
