GWL/Modular Balancing Rail in action
Balancing rail is a setup of 8 balancing resistors connected to the metallic rail-holder.
Each resistor is a20W, 0.68Ohm ceramic model. With balancing voltage of3.65Vit will pass through the current of5.36Amp, releasing some19.6Wof heat.
The metallic rail al
Moving on with the GWL/Modular Smart Pack Guard project
GWL/Team is testing and verifying the functions of theSmart Pack Guard that works as theUltimate Battery Control System.
More details to come soon….. (sooner or later)
The innovative ELERIX cells 50AH and 110AH
The innovative ELERIX brand cells are coming. It is a long way for a product to make it through the product development, product review, testing, evaluating, reviewing, branding…
Until the product is ready on stock to be sold in mass quantities.

High quality battery packs with a modular set-up
This photo showsthe test installation for a high-performance quality pack using the ELERIX 50AH cells.The two cells are installed in parallel to reach the 100AH capacity. The massive copper terminal platesmake sure there will be a minimal loss of the energy during the peak discharge
The LFP 40AH cell hammered to death
The photos are showing the read-to-go steps ofthe abuse by the axe-hammer in the hands of the fire-fighter.
The cell had to be hit several times to produce any significant effect. As seen from the reading of the IR camera, the temperature ofthe hot area has reached some 108°C.&
The overcharge test of the TSWB 40AH cells
The summary of the data for the overcharge test of the TSWB 40AH cells.
- The over charge test wasperformed for 30 minutes.
- The voltage percell increased up to 8V.
- The temperature of the packreached up to 130°C.
There was no fire, no explosion, no strong gas leakage.
The field test demonstration of lithium cell abuse
In the spring of 2019, the GWL/Team has organizedthe lithium cells abuse demonstrationto verify the performance in real conditions. There were following goals of these tests:
- Make the real field test demonstrations of the over-charge, short-circuit and fire abuse of the various cells: li-
Can a lithium iron phosphate (LFP) battery burn?
The answer is simple: yes, but it is not easy.The LFP lithium battery is made of materials that are flammable and it will burn, if overheated.
The photos showthe process of fire on a prismatic lithium battery. The battery was fully charged and then set to fire by a flame-thrower. As you can
