The blogger and YouTube channel Tinker andHeimwerker.de has extensively tested the 48V 100Ah battery on its website and rated it very good.
Quotes from a trained electrical engineer and YouTuber @tueftler: Tinker andHeimwerker.de:
, "In this article, I'll show you how to install a modern Daily Active Balancer with Bluetooth into a finished battery. As an example, I've used the inexpensive 4800 Wh LiTime battery (metal rack-mounted with UL certification). I'll explain in this article and video why it can be beneficial to upgrade existing batteries or storage systems, which usually already have a balancer, with an additional balancer featuring Bluetooth functionality. As always, I'll show you how such an installation can be carried out using circuit diagrams and pictures."
Why might it make sense to install an additional balancer in a finished battery/storage system?
Most readers are probably aware that a modern lithium iron phosphate battery requires a balancer to equalize the cell voltages, ensuring a long lifespan and high capacity. If you're building your own battery, installing a balancer is practically mandatory; I've explained this many times in my numerous LiFePO4 battery projects, see [link/reference]. z.B. 24V/5000Wh LiFePo4 DIY project or our 12V LiFePo4 tutorial project. A balancer is usually already included with a purchased battery. A battery management system (BMS) is installed. Unfortunately, very often the BMS only contains a passive balancer or a very weak balancer. These balancers often only equalize the cells with very small currents, often less than 25 mA, to equalize the voltages.
