The Soonwell B-98V V Mount Battery is a 98Wh capability battery with twin D-taps and a USB port.
Batteries might not be essentially the most thrilling items of equipment, however they’re important to simply about all the things we do.
Who is Soonwell?
You are in all probability like me and have by no means heard of Soonwell. Soonwell focuses on lighting and energy options for picture, TV, broadcast and the movie trade. They have been round since 2009.
- Capacity: 6600mAh / 98Wh
- Maximum Charge Voltage: 14.8V
- Max output present: 6.6A ,
- 5-level LED cost readout
- 2 D-tap energy interfaces
- 1 USB energy interface
- Size: 138mm x 91mm x54mm
- Weight: about 0.72kg / 25.3 ounces
There is nothing notably particular concerning the Soonwell B-98V V Mount Battery. It has a 98Wh capability, a most output present of 6.6A, 2x D-Tap outputs, in addition to a USB output.
There is nothing unsuitable with the batteries construct high quality, however for my part, so far as the surface casing is anxious, it’s not fairly as properly made as an Anton Bauer or CORE SWX for instance.
I like how Soonwell has put finger grips on the perimeters of the battery. This definitely makes it simpler to carry onto if you end up attaching or eradicating the battery.
The battery attaches properly to V-lock plates and there’s no wobble or gaps between the plate and the battery.
The battery has covers for the D-tap and USB ports which is a pleasant contact. Numerous batteries with D-tap and USB ports don’t have any covers.
If you’re solely utilizing a single D-tap port you may hold a canopy on the opposite one.
I additionally like that the D-tap ports are situated on prime of the battery and never on the perimeters.
In a pleasant contact, there may be additionally a written warning about which method to insert your D-tap connector.
He solely criticism concerning the construct high quality that I’ve is that I did discover it fairly tough to insert sure D-tap connectors into the battery. But, in saying that, this can be a downside that I discover exists on a whole lot of batteries, from a wide selection of producers.
The battery ought to cost on any V-lock battery charger. I attempted it on Anton Bauer, Sony, and IDX chargers and it labored.
Size & Weight
The B-98V is across the identical dimension and most typical 98Wh batteries (138mm x 91mm x 54mm), and it has a weight of (0.72kg / 25.3 ounces) which can be pretty frequent for a 98Wh battery.
The batteries are a pleasant top and width and this implies they are going to stay streamlined in your digicam or battery plate.
With so many mini V-lock batteries available on the market which are round 98Wh capability, the the explanation why you’d select a bigger sized battery such because the Soonwell could be for the twin D-Taps, and the worth.
Is a Chinese battery going to be dependable?
There isn’t any purpose why it received’t be any extra or any much less dependable than every other lithium-ion battery.
The batteries have been correctly licensed by the related governing our bodies who take care of batteries. What can be good is that the battery complies with IATA, ICAO, and UN rules for air transportation with out restrictions.
What cells are getting used?
I used to be curious to search out out simply what cells had been contained in the Soonwell battery. Soonwell instructed me that:
All digicam batteries are assembled from a number of 18650 batteries packs. The finest producers of batteries around the globe are Sony, Samsung and Sanyo. In reality, whether or not it’s Samsung or Sanyo’s batteries, all cells shall be divided into three ranges of A,B and C. The decrease the ranking, the cheaper the worth and naturally the more severe the efficiency. Soonwell solely purchases the Class A cells type these prime producers and is ready to present the producer’s MSDS report. Below is the Samsung MSDS report of Soonwell B-98V digicam battery:
I discovered it refreshing that an organization was prepared to supply me with documentation and inform me precisely what cells are getting used of their batteries. This is one thing most battery producers wouldn’t do.
Battery Pack: Cells Voltage Management
Battery cells have an unstable chemical composition when a cell is manufactured. This signifies that its inner voltage is totally different than different cells. A standard methodology to scale back battery life is to mix all of the cells which have huge voltage distinction into one battery pack.
What Soonwell does, is to gather every cells voltage knowledge, after which group these cells whose measured worth error lower than 0.001 V right into a battery pack.
Battery Durability take a look at
After the battery pack is assembled, the pack is joined with the battery motherboard, after which positioned in a sturdiness cycle take a look at room for greater than 8 hours.
The Soonwel battery motherboard makes use of a safety-oriented design with three modules: over-discharge safety, over-charge safety, and short-circuit safety.
Max Charging Voltage Difference
Since battery packs are made up of a number of battery teams, when charging, all battery teams are charged in flip.
For instance, let’s assume a battery packs (MCVD) is 1V, that signifies that when one group of batteries has already absolutely charged, the opposite group may nonetheless be at 13.8v, and the motherboard stops charging. In whole, the battery pack is simply charging to round 93%.
Soonwell claims that with their batteries every group will be charged to 14.78v when any group is absolutely charged. This signifies that the entire battery will get charged to 99.8%.
Surely there isn’t going to be that a lot distinction between 93% and 99.8%? Well, sure and no. Wait till your battery had been charged 130 to 150 instances (that’s regular use for greater than half a yr). A well-built battery can keep its full cost, nevertheless, a poor high quality battery might have its capability decreased by as much as 30%-40%.
According to Soonwell, their batteries have a life cycle of as much as 500 costs.
Now, I’ve no manner of independently verifying any of those claims, however Soonwell does appear to have all the right documentation to again this up.
Soonwell makes numerous equipment for his or her batteries, together with a V Lock Mounting Plate Power Supply Splitter ($103 USD) which is helpful if you wish to energy a digicam, or a monitor, or each from a single V-lock battery.
The Mounting Plate Power Supply Splitter has a D-tap, 5V USB in addition to two DC outputs, one is 7.2V and the opposite is 12V. You can mount the plate onto 15mm rods.
Not solely do you get a bunch of adapter cables, however Sonnwell additionally gives an LP-E6 Dummy Battery Pack Adapter.
Other equipment embrace a BP to AN Battery Adapter ($60 USD) that allows you to use Anton Bauer Gold mount batteries, a D-Tap USB Adapter ($16 USD), and a 110cm D-Tap Plug to Barrel Jack Cable for BMPCC ($34 USD).
The Soonwell B-98V V Mount Battery retails for $160 USD. This definitely does make it probably the most cost-effective 98Wh batteries available on the market. In reality, I couldn’t discover every other 98Wh V-lock batteries available on the market that was cheaper than $199 USD.
Soonwell additionally makes the B-250V V Mount Battery, a excessive capability (250Wh) model that’s accessible for $390 USD.
There is a endless record of 98Wh v-lock batteries which are accessible. Here are just a few:
Core SWX Hypercore Slim V-Mount Battery $299 USD weight: 0.64 kg
Core SWX Nano V-Mount Battery $229 USD weight: 0.64 kg
IndiPRO Tools Micro-Series V-Mount $239 USD weight: 0.73 kg
SWIT PB-S98S 14.4V 98Wh Dual D-Tap $265 USD weight: 0.8 kg
Intellytech Socanland 14.8V 98Wh $199 USD weight: 0.7 kg
Hawk-Woods Mini V-Lok 14.4V 98Wh $345.60 USD weight: 0.5kg
Hedbox PB-D100V Pro $215 USD weight: 0.78 kg
CAMLAST 98Wh 14.8V $199 USD weight: 0.91 kg
Fxlion Cool Black Series BP-100S $236 USD weight: 0.77 kg
Bebob Factory GmbH V98 $320 USD weight: 0.6 kg
Numerous potential consumers of V-lock batteries are in all probability going to have a pre-conceived bias that can direct them in the direction of a model that they know. Buying a battery from a model you will have by no means heard of is definitely going to make it tougher for Soonwell to promote their batteries exterior of China.
A battery is only a battery proper? If the identical cells are being utilized in a dearer battery, are you merely simply paying for the identify on the casing? Maybe.
I couldn’t fault the Soonwell battery. It works as marketed, and most significantly, though it is vitally inexpensive, they’re nonetheless utilizing high-quality cells contained in the battery.
For $160 USD, it’s the most inexpensive 98Wh V-lock battery I’ve come throughout. Just how properly the battery stands up after a yr or so of use is one thing that shall be fascinating to see.
