Can you mix different sizes of battery is one of the most common questions I see about parallel charging. The answer is, yes! I’ll tell you why.

If you’re interested in parallel charging, I made the best parallel charge board you can buy. WHY IS IT THE BEST PARALLEL CHARGE BOARD IN EXISTENCE?



How To Connect 6 Volt Batteries in SERIES and PARALLEL for SOLAR

Create a 450 Amp Hour 12 volt battery bank using four 6 volt deep cycle batteries for your off-grid solar-powered RV, camper, tiny house, van, or boat. Links to batteries and cables are listed below.

I upgraded my RV’s 12 volt battery bank to 450 amp hours using four 6 volt deep cycle AGM batteries ordered from I connected the four 225 Ah 6 volt batteries using a series parallel configuration. Each pair of batteries are connected in series, then the pairs are joined together in parallel. The result is a 12 volt battery bank with plenty of capacity to power an RV or small off-grid tiny home for a couple days depending on your needs.

Easy to Follow First AGM Battery Bank Parallel Configuration 2 qty 12V 35 AH VMAXTanks AGM Batteries

This video will show you how to connect two VMAXTANKS 12 volts 35 AH AGM Batteries using Parallel Configuration with charging cables. I also wired charging cables to the batteries. This video will also show you how to charge multiple batteries using one charger or maintainer. After wiring the batteries using the parallel configuration, the charger, as far as it can detect, it will treat your batteries as one unit. The catch… get the appropriate amperage for the charger you can afford for fast efficient charging. Pay attention to the manufacturers recommendation. VMaxTanks recommends a 3 amps to 7 amps chargers – DO NOT Exceed 7 amps.
I got the 5 amps Model 1205 VMTanks Smart Charger. This smart charger falls between better and best (based on AH). Smart Charger 1207 is marked “best” for 45ah to 75ah

Parallel Configuration keeps the batteries’ voltage at 12 volts but doubles amp hours (two identical battery configuration). These VMTanks AGM Batteries will be used as a power source for my new Newport Vessel 55 trolling motor.
My first AGM Battery Bank 2 qty 12V 35 ah VMAXTanks Deep Cycle AGM joined using parallel configuration
With 2 qty of 12v 35ah joined using parallel configuration, I ended up with 12 volts 70 ah

Application: These VMTanks Batteries will be used for my 55 lbs Trolling Motor and as a backup power source for my travel trailer.
While in the trailer, the charger will be charge using the smart chargers connected to AC power in my travel trailer.


ISDT D2 Two Channel Charger With ISDT Safe Parallel Charging Boards

Wade turned me on to ISDT and there is no looking back. Covers All My 2S And 3S Charging Needs Figure my “current” setup (thats a charging joke) will serve me well for many seasons. A great way to prolong battery life and get the most out of them is with a “smart” charger like this one. Parallel charging can be sketchy so a safer system is always a no brainer for me cause I gotz no brain. LOL. Be Safe. Use Quality Chargers and Batts.


“90mm Graf Perlchen” FPV HighEnd Racer ★Parallel Charging; LED-Strip & FC-Entkoppelung★
