ThunderSky Winston TSWB-LP12V50AH

ThunderSky Winston TSWB-LP12V50AH 

Battery, LiFePO4, 12V, 50Ah

State-of-the-art technology for electricity storage!

High-performance Lithium battery with yttrium content. LiFeYPO4/LiFePO4 (voltage 12 V, capacity 50 Ah). Original Winston WB-LP12V50AH battery (formerly ThunderSky TSWB-LP12V50AH).

Properties

• Lithium-Yttrium-Iron-Phosphate (LiFePO4 & LiFeYPO4) Technology
• It does not contain any toxic substances, poisons, corrosive substances or acids
• Completely safe: does not burn, does not explode, does not contain liquid electrolyte
• Low self-discharge
• Long service life
• Does not contain a balancing system – cells assembled according to the exact capacity, operating voltage must be monitored as a whole
• Fast-charging option

Optimal discharge current: 25 A
Maximum charging current: 50 A
Optimal charging current: 25 A
Recommended subsequent charge: 14.6 V
Minimum voltage: 11 V
Maximum Discharge Current: 3C continuously (continuously for a maximum of 30 minutes after full charge)
Thread size at terminal: M8

Note:
Monolithic 12V batteries have no PCM (no electronics) inside. They consist of finely balanced cells with identical power. The battery must be managed and operated as a single monolithic 12V block. Not recommended for use in series. For a system with a higher voltage of 24/36/48 V and more, we recommend using individual cells (LFP050AHA) 50 Ah + BMS123Smart.

These batteries are suitable for all traction applications, including electric vehicles (EVs). They are also ideal for stationary applications – for example, as energy storage.
They can also be used to start internal combustion engines. In principle, the use of LP 12V batteries for starting does not require any special electronics, but it is very important to observe the minimum and maximum voltage, so we recommend using a voltage indication unit that will inform you about the current voltage. This is especially important when starting frequently.

There is no self-discharge. It can be recharged in any state of discharge – there is no memory effect. LiFePO4 is a very safe technology, it does not spontaneously combust, it does not react with moisture or oxygen.

BASIC SPECIFICATIONS

All goods are delivered new directly from the manufacturer.
The original wooden box contains 6 batteries, has dimensions of 543 × 509 × 425 mm and weighs 58 kg.
The batteries are charged (conservation charge).
Before you can use them, they must first be charged with a low current.
The first charge should not exceed 0.5 C - e.g. for a 50 Ah battery it is 25 A.

Tip! For initial charging of multiple batteries, plug them in parallel and the charger outputs should be connected to both ends of the parallel battery rows.
