Anyone out there with Zivan Modifying experience? I have a Zivan NG3 230 volt unit that I’m thrilled with but I’m thinking about updating it to a 144v pack or using it for Lipo applications. The vendor is very closed lip about modifications and only recommends that I send it to them for service, read $$$. Someone here once stated “ I adjusted the pots and adjustments in the Zivan to x and x for my applications. Now my unit has the factory seals but I bought it second hand so I probably don’t have any valid warranty claims anyway and I love the way the unit charges my 120v lead pack. So any thoughts? Thanks again. ……….. lou-ace.
