Designed for LiFePO4, Li-ion and LTO chemistries, it supports a wide range of configurations including 8S, 10S, 14S, 16S, 20S, 21S, 22S and 24S, making it suitable for energy storage systems, DIY power walls, backup power, electric mobility and other multi-cell applications.\u003c\/p\u003e\u003cp\u003eThe balancer uses active energy transfer technology rather than simple passive bleeding. It moves energy from higher-voltage cells to lower-voltage cells with a balancing current of up to 4A, allowing it to correct voltage differences more quickly than low-current balancers. The integrated smart algorithm continuously monitors cell voltage differences and prioritizes cells with the largest deviation, so the most unbalanced cells are corrected first for efficient equalization. The device operates automatically: it starts balancing when the cell voltage difference reaches approximately 10 mV and stops when the difference falls below about 5 mV, reducing unnecessary cycling and power loss. It can operate while the pack is charging, discharging or idle, supporting continuous maintenance of cell consistency.\u003c\/p\u003e\u003cp\u003eThe balancer is designed for use in demanding environments, with a structure intended to handle wide operating temperatures and sustained operation under load. A compatible Bluetooth module (where used) and dedicated app interface allow real-time monitoring of cell status and adjustment of key parameters from a mobile device, giving clear insight into pack health. Its compact footprint allows installation in tight battery enclosures, on custom battery packs or within larger energy storage cabinets without taking up excessive space.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy It's a Smart Choice\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMaintains tighter cell voltage consistency across 8S-24S packs, supporting better overall pack stability and usable capacity.\u003c\/li\u003e\n\u003cli\u003e4A active balancing current shortens equalization time compared with low-current or purely passive balancers.\u003c\/li\u003e\n\u003cli\u003eAutomatic start\/stop logic and smart prioritization reduce manual intervention and help extend battery service life.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eQ: Which battery types are supported?\u003cbr\u003eA: It is compatible with LiFePO4, Li-ion and LTO packs configured as 8S, 10S, 14S, 16S, 20S, 21S, 22S or 24S in series.\u003c\/p\u003e\u003cp\u003eQ: Can it balance while the battery is charging or discharging?\u003cbr\u003eA: Yes. The balancer can actively equalize cells whether the pack is charging, discharging or resting, as long as it is correctly wired and within its operating limits.\u003c\/p\u003e\u003cp\u003eQ: Do I need to turn it on and off manually?\u003cbr\u003eA: No. The unit starts balancing automatically when the cell voltage difference reaches about 10 mV and stops when the difference is reduced to about 5 mV.\u003c\/p\u003e\u003cp\u003eQ: Is a Bluetooth module required?\u003cbr\u003eA: The core balancing function does not require Bluetooth. The optional Bluetooth module and app provide additional convenience for monitoring and fine-tuning settings.\u003c\/p\u003e","brand":"HitMyNeed","offers":[{"title":"Default Title","offer_id":49775322398997,"sku":"100000116","price":108.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/6105\/5509\/files\/4a-smart-active-balancer-for-8s-24s-lifepo4-li-ion-lto-1-hitmyneed.jpg?v=1770964909","url":"https:\/\/hitmyneed.com\/products\/4a-smart-active-balancer-for-8s-24s-lifepo4-li-ion-lto","provider":"HitMyNeed","version":"1.0","type":"link"}
