EV_UTV

Hey, I have upgraded mine recently and used alot of the recommendations made here so thanks to all. I also went with the Big Battery Eagle 2's. Gen 1's, 51.2v 60Ah x 2 in parallel. About 6.0kWh total. I found the batteries through tech direct on their ebay store and they were well priced and warranty provided. Install was just as described above. They were same width as old batteries so fit nicely on inboard trays. My batteries came with short metal straps and I used these as hold downs for batteries with one end attached to threaded hole in battery and other to battery tray with self tapping screws. Ill monitor this and add something more if needed. I kept the DeltaQ charger and loaded it with profile 233 but I am currently only charging it with solar panels and going direct to batteries. I installed bus bars to facilitate easy connection of a solar charging circuit and use a Victron charge controller connected to three 540W panels. I'm at an off-grid place so I had these larger panels available. This solar method seems to be way more efficient than using the charger. In just over an hour on a sunny day I get close to 1.5kWh or 25% of capacity. A future plan is to mount a small panel on the E1 so it charges all of the time. I added a battery meter that I got from bigbattery.com and mounted it in the dash. The location just above the charging lights works well as nothing behind the dash here and easy access for wiring from hood compartment. So far the new batteries work great. No more error messages when I go up hills and speed has increased alot.
