Your math is spot on. The battery is 42 lbs so there's no chance it will fit in the 1500 sized case. I've never used the flashlight on the 500. Forgot it was even there. The Jackery and the assembled system both have different uses. The Jackery is portable and getting power is immediate. The...
Thanks for the link. Very informative. I was surprised to see I only need about 3.5kW to cover 97% of my energy needs. I have to conduct a cost/benefit analysis to see if I want to cover 100% or more. I'm assuming the estimate is for grid-tied and does not include the cost of batteries and...
The hammer lug tool didn't work. Picked up a hydraulic crimper. It worked, but I should have purchased the 6/8 awg Anderson lugs Joe Ham suggested. Oh well, live and learn.
I have an out-of-production Quickie P100 Powerchair from Sunrise Medical. It has a 24V power system but came with two battery boxes with 12V Deka 8AU1 AGM 32ah batteries. Each box has ring connectors, a 30amp fuse, and SB175 connectors for plugging into the power control module. I replaced the...
I bought the ABYC DC wire size chart. I mistakenly used 8ga wire because I didn't understand what "load" meant on the Renogy scc. Thanks to Bud Martin for setting me straight. The wire chart indicates I need 2/0. My batteries have an SB175 Anderson connector. The 3' parallel cable is 6ga. I will...
I bought two of them from their Ebay store. They weigh 42 pounds each. I haven't connected them to anything yet because the ring connectors and wires are too big to connect to my Renogy 40amp MPPT controller. Largest wire for the Renogy is #8. Battery Evo uses #6. Waiting on parts so I can...
You could connect a Kill-a-Watt to the extension cord from the inverter leading to your load. It will provide you with the run-time and load output. Kill-a-Watt is about 30 bucks on Amazon or at Harbor Freight.
Same here. Label said 115v at 3 amps. 345 watts but I had no idea what that meant. I plugged the fridge into a Kill-a-Watt for seven days with the electronic control panel on. Ice-maker and cold-water on. The average was 55w per hour. I still didn't know the start-up load. I plugged the fridge...
Battery Evo sells a 120aH/1.5 Kwh battery not available through BigBattery. I bought one off of Ebay recently for $500 plus sales tax. Externally everything looks the same as a BigBattery. I wonder what it looks like on the inside? Will Prowse, please do a teardown!!!
Bigbattery has a 10...
I just ordered the TEMCO Hammer Lug tool. Same as in Will's videos. I probably won't be using it much, but it's only $20 and I know it will do the job.
My name is Randy and I'm a middle school educational technology specialist. I'm familiar with educational based solar projects for kids but not for home or RV based applications. I've been watching videos from Prof. Hobo and Will to get a solid foundation. We have a strong STEM (Science...
I bought two 1.5 kWh Battery Evo units. A cable with SB175 to ring connector was included. It looks like the same cable from BigBattery for $12.95 The BigBattery series connector cable is $29.95 plus $10 shipping and sales tax.
I can see the difference now. I just saw the power button and LCD. I didn't notice that the Anderson plug was there as well.These are definitely different from the Bigbattery/BatteryEvo in Will's video. BatteryEvo has answered my email messages in a day or so. You can also call them. (818)...
I have a Renogy MPPT 40a charge controller. The largest cable size it can accommodate is 8 gauge. My Battery Evo has an SB175 connector with 6 gauge wires. I ordered an SB175 Anderson style connector for 4 gauge. I'm not sure if the 8 ga wire will hold the crimp in the 4 ga connector. I just...
You need to consider what MisterSandals posted and determine your usage. If you can get by with these numbers, you will be OK.
The description of what you want to build sounds similar to the smaller capacity "solar generators" from Bluetti, Jackery, Renogy, etc. It could be fun to DIY your own...
Will has a video where he tears-down the Bigbattery. The top of the cells and BMS are under the plate with the power button and LCD readout. The cells will be vertical if you place the battery with the back-side down. There is another YouTuber who did a tear-down of the BatteryEvo but I can't...
Thanks for the links. I spend my day in a manual wheelchair but have an old electric. The AGM 8AU1 32 amp hour batteries for my chair finally died. I happened to have two Ironworks LiFePO4 12V 44.6 amp hour batteries in my garage. The Ironworks fit in the battery box so I hooked them up. I...
I have an AIMS 1500 MSW inverter/charger with an automatic relay. There is a separate switch for the inverter and a separate switch for the charger. With both switches off, shore power passes through to whatever is plugged into the AC outlets. If shore power goes out and the inverter is off...
How did that work out?
I have a similar question regarding the use of a 24v lead-acid battery charger with LiFePO4 batteries. I recently replaced two 12v 32ah AGM batteries with two 44 ah LiFePO4 batteries on my wheelchair (Quickie P110). The charger doesn't have a readout. The controller on...
I've seen that configuration before but my battery has a SB175 connector, not posts. I was thinking of making a very short Y-connector with one branch of the Y coming from the solar charge controller and the other branch of the Y with an inline fuse going to the inverter.
Here is my setup. BougeRV 12v, 180 watt solar panel, Giandel 1200w/2400w PSW inverter, Renogy Rover 40 amp MPPT solar charge controller, Battery Evo 120Ah battery X 2 in parallel. Renogy SCC will take 8 awg or smaller. 8 awg from Renogy to Giandel inverter. Anderson SB175, 6 awg from battery to...
The connector didn't fit well into the hammer crimper. Energy from the impact of the hammer wasn't enough to crimp the connector. The 4AWG connector is quite thick.
Sorry. I posted and referred to the wrong pic. The Renogy SCC low voltage disconnect is 11V. The battery never dropped below 13V but the Giandel gave me a low battery error light. I'll give it another go in the morning and record some video.
I have all the components except for the solar panel and batteries laid out on a bench. Solar panel is in backyard. Batteries on the garage floor.I still need to mount everything on plywood then mount that to a wall. I'm having problems pulling anything over 400W from the inverter when the...
The EVO comes with an SB175 to a ring connector cable. I built an SB175 Y-connector splitting off to two SB50 connectors. One SB50 connects to the solar charge controller and the other to a fused line going to the inverter. I recycled some cables I already had. Works perfectly now.
Thanks for...
Yeah, the AGM's are dead. I was thinking about trying to bring them back just to have extra deep cycle batteries but I don't think it's worth the hassle. The Ironworks batteries are about 10 years-old so I don't expect much from them capacity-wise. I haven't capacity tested them. They were...
I'm only using the LiFePO4's because I had them already and I wanted to see whether or not they would even work with my wheelchair. I don't use the chair much, and the original AGM's for the chair are rather small and inexpensive. I think I'll buy a pair of AGM's for the chair and figure out...
They are studs not bolts. Sorry for the bad description. So the better setup is batteries on #1 and #3 with SCC and inverter on #2?
I'll be running a 200 amp ANL inline fuse from the bus bar to the inverter. My inverter is rated at 40 amps so I'll be running a 40 amp ANL inline fuse to the...
