More Information


This BSLBATT 48v 20ah lithium battery Pack is shrink-wrapped with flame retarded fish paper inside to improve safety. We test each cell first before we build the battery pack to ensure the cells are properly balanced. We build every battery to order nothing sits on the shelf here as we want to only send the freshest battery and we educate all our customers not to leave the battery sitting for a long time without charging as well.

The High-Performance 48v 20ah lithium battery e-bike BSLBATT® offers high-level safety through the use of rhombus cells in Lithium Phosphate technology (LiFePO4 or LFP).

lithium battery factory

The BSLBATT® batteries for 48 volt electric golf cart range has been designed to replace lead-acid batteries advantageously, by offering a quadruple energy density for an equivalent weight and size.

Thanks to its technology, the High Performance 18650 battery pack 48v 20ah lithium ion battery BSLBATT® can be installed in any position (vertically, lying on the side, or head down).

The electrical parameters of the BSLBATT® 48v 20ah lithium battery are compatible in all respects with those of an AGM lead battery of 48V. In the vast majority of cases, the batteries for 48 volt golf cart charging system can be kept the same and no additional accessories are required to perform the replacement.

The products BSLBATT® 48v 20ah lithium ion battery are light, compact, efficient, and can be used for all types of uses and applications. BSLBATT® are designed to drop-in replacement of old generation batteries (Lead VRLA, AGM or OPZ batteries) in 12V, that is low performance and harmful to the environment (use of heavy metals and acid electrolytes).
