After purchasing a Battleborn LiFePo4 12V 100 AH Lithium Battery for our RV, we discovered that our original WFCO WF-9855 Converter/Charger that came with our RV would not charge the new lithium battery to it's full capacity and it also charged it VERY slowly. To resolve this issue, we purchased and installed a new Converter/Charger from WFCO made specifically for LiFePo4 Lithium Batteries. The model number is WF-9850L2. In this video, we show how we replaced the original Converter/Charger with this new one and we also show the results of just how big of a difference it has made in charging the Battleborn Lithium battery.
