Are Lithium Iron Phosphate batteries easily damaged?
GimmyTree replied to GimmyTree's topic in General RV Information
There is a bit more to it than I thought. Okay so I will make sure to charge it only to 14.2V, not it's full capacity. I'll take a look through that site to get a bit more of an education on lith batts. The last thing I need is to have my van catch fire because I did something wrong with the battery. -
Alright thanks. I'm not familiar with soldering but this is probably what I'm going to have to end up doing.

I have just ordered a very pricey LiFePO4 battery to go with my 160 watt solar panel. Now I want a MPPT controller and I was hoping someone here could confirm this is the correct controller for the battery and panel. I believe it is the correct controller but I would like a second opinion please. The charge controller: https://fazcorp.co.nz/collections/mppt-s...v-ml2430-1 With a MPPT Bluetooth Communication Module so I can monitor the solar system from my Amazon Kindle: https://fazcorp.co.nz/collections/mppt-s...ies-bt-1-1 Solar panel: Standard power: 160 Watts Maximum power voltage: 17.8 Maximum power current: 9.0A Open Circuit voltage: 21.1V Short Circuit current: 9.5A LiFePO4 battery: Nominal voltage: 12v Capacity: 100Ah Discharge cut-off voltage: 8.4v Operating voltage min 11.5 V - max 14.8 V At 80 % DOD Optimal discharge current < 50 A Charge voltage: 14.6v

The battery I purchased has a charge voltage of 14.6 I think I'll look into buying a charge controller that is definitely for a LiFePO4 battery, The PWM controller I currently own does have a lithium option but it doesn't specify LiFePO4. So I'd have to gamble on it being compatible with LiFePO4 batteries, and I'm not willing to gamble. -

Thanks for the information guys. Another thing is; even though my PWM controller is compatible with a Lithium battery, the battery in the OP link that I want to buy is only compatible with a LiFePO4 charge controller and my PWM controller doesn't specify what type of lithium battery it works with. Do you think I should by a LiFePO4 charge controller like this?: https://www.amazon.com/Genasun-GV-10L-Controller-Lithium-Batteries/dp/B01N6AXQZH/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=zk0c5-20&linkId=2a1ee7abd062307ea19a3cb9a8e644ce -

Thanks for the links, I'm going to have a good read up after work. -

It is actually more expensive. The battery I plan to buy costs $949NZD ($640USD). Shipping a lithium battery within NZ only costs $4USD and shipping lithium batteries internationally is not allowed anyway unless the battery is already installed in the equipment it operates. -
Which battery is better for a 160 watt solar panel?
GimmyTree replied to GimmyTree's topic in General RV Information
I don't own a RV, I own a 1999 high roof Toyota Hiace which I plan to live out of full time. It's still in the conversion stage and because I can only work on it one day per week, I've got a two more weeks before it's finished. I do plan on doing some traveling (I'm located in NZ) but generally I'll be staying in the same town because I have a full time job. The traveling will be done on weekends and holiday's. I'll be mostly boondocking near a beach where I previously lived for nine years, so I know the area well. I have a pure sine wave inverter and I'll be powering a laptop, 2 x kontiki batteries (by plugging the kontiki charger into the inverter), a mobile and a kindle. A kontiki is a fishing device, if you're not familiar with it. -

It's currently 5am and I have work in a couple of hours but I'll have a good read of those sites when I get home. Thanks for the links:) -
I was just about to buy the battery below for my 160 watt solar panel but there is a lot of different guidelines and warnings on the battery: https://www.trademe.co.nz/motors/caravan...ed0d07-003 My questions are; Are Lithium Iron Phosphate batteries easily damaged compared to lead acid batteries? Is a newbie like myself better off with a lead acid battery?
-
Ah good answers, that explains things. I'll have to watch a few YouTube video's on how to crimp MC4 connectors without a crimper.

This one: https://www.trademe.co.nz/business-farmi...b7393b-001 Or this one: https://www.trademe.co.nz/motors/caravan...1883d5-001 I know the lithium iron phosphate batteries are better than the lead acid batteries, so I assume all lithium iron phosphate batteries are deep cycle batteries?, is my assumption correct?

My solar panel is 160 watts and I currently have a PWM solar charge controller (30V) which apparently aren't very efficient and loss 30% of solar power. So a MPPT solar charge controller was recommended. My question is; will this controller be okay for a 160 watt solar panel, or should I buy one of the smaller ones? https://www.amazon.com/dp/B07429RK43/ref=as_li_ss_tl?psc=1&pd_rd_i=B07429RK43&pd_rd_wg=2Tk2y&pd_rd_r=92XADJVX85X17T90PT7F&pd_rd_w=R7yk9&linkCode=sl1&tag=vehicledwelling-20&linkId=8b93017dcab6009786a3f874e2280e87

Thanks for the information. Much appreciated:)

Here is the solar charge controller with the wires and connectors that came with the kit: https://ibb.co/xLM72kS This is the pure sine wave inverter with wires and connectors: https://ibb.co/VQJT3Sz And the solar panel wire connectors: https://ibb.co/Qbb1CrW I have one pair of mc4 solar panel connectors on order so I can connect the solar panel to the wires. I assume the white wire (which is quite long and has positive and negative wires in it) connects to the solar panel and the solar controller, correct? Do I need to buy positive and negative wires to run from the battery to the controller? The solar kit I got doesn't seem to have those wires. The kit was suppose to have come ready to set up, does it look like I have everything to setup the solar panel kit? (battery is still to come)
